at least so far anyway.. lol ..

boy i made a mistake .. ONCE ... of thinking violets were so cute ...

and as it grew.. i noticed it sprouted in spring to a seed pod.. then flowered.. then seeded again.. not to mention growing underground and clumping ...

then when i pulled them out.. and as i worked.. threw them in the grass.. lo and behold.. they were in the grass ..

crimminey.. i moved .. lol ...

and then the new house.. its all over the 5 acres.. and frankly.. one of the few things in the meadow [i dont really call it grass or a lawn out here] .. the only thing that stays green when everything else browns out 7/1 to 9/1 ... at 400 feet.. it looks like a nice green lawn .. lol

that is the long way of saying i went zen on violets in the lawn.. lol ...

what other things took you years to eradicate from your garden.. or are you still working on eradicating ...

oh.. 3 years to kill an underground poison ivy vine ...

RE: what plants are impossible to kill

When you say "impossible to kill" does that mean by ordinary means or can we include nuclear weapons - even small ones? It does make a difference in answering the question.

Just sayin...

Just talking about newbie mistakes, things that grow way faster than one's appreciation for them... evening primrose. Tansy. Unless you like the scent of gym socks on an enthusiastically spreading plant, yarrow.

Scourges I hope you never get, Aegopodium podagaria (bishop weed,) Convallaria (lily of the valley,) Hedera helix (English ivy,) Akebia quinata (chocolate vine - clever way to market a weed!)

Nandina. Ugh-a-rama!

RE: what plants are impossible to kill

i mean.. you cant just pull them out and be done with them.. that you have to resort to double digging and sifting the bed.. or turn to chemicals ...

in theory.. no plant is impossible to kill.. you know that..

let me rephrase it this way.. what took you the longest to get rid of .....

i can add grape hyacinths on some level.. i will always have them.. but dont ever try to get rid of them ...

and i gave up on buying the same $100 worth of annuals every year ... whats that all about.. may as well bang my head on a wall ... find something that reseeds itself in a mild manner ... [well, talk about distracted ... lol.. that is supposed to go in my other post.. left behind plants.. oh well.. i will paste it there.. lol ...] .. annuals are easy to kill.. ma nature takes care of those.. lol ...

RE: what plants are impossible to kill

A few years ago I decided to get serious about the violets. I think I'm about 90% free of them, but you can't let your guard down. Just one season of ignoring the stray seedlings or worse yet the flowers and you can be back to square one in a flash. I constantly look for them and yank them out immediately. If I see a flower, it gets pinched. Persistence, persistence.

A friend was trying to thank me for some plants I had given him. He dug up some things from his yard, among which was a violet. I didn't want to tell him...and it was not in me to kill it...not directly. I put it in the landscape waste recycling, figuring it would survive the trip to that giant suburban compost pile and flourish there.


 o
RE: what plants are impossible to kill

I have never experienced the plants mentioned above to be impossible to kill. The only one that makes resistance of some sort is Convalaria majalis. My wife treated it with Round up some years ago, and it has been looking ill for some years, but bounced back eventually. One that is really worth mentioning here is Cicerbita alpina(the worst of them all).

I like violets in the lawn. I think they're quite pretty. When the violets and the dandelions bloom together in the spring, what a site! It is a glorious sea of lilac and yellow. Stunning. Seriously. (I am NOT being sarcastic!). I personally think we suburbanites spend waaaaaay too much time, money, and resources trying to upkeep a "perfect" lawn. For what? Eh, the weeds are green from a distance, so who cares? I leave that for DH. I'd rather play in the flowers :0)

For me it's yucca. Have been working on them for 20 years. They love the high plains desert. Add to that bindweed and Canadian thistle.

RE: what plants are impossible to kill

Lemon balm. I planted an herb garden, but it proved to be too far from my kitchen to be useful. So I let it go. Today, in that spot, I have a nice clump of chives that flower every spring, and a million lemon balm plants of various sizes all over that hillside. At least they smell really good when I pull them out.


 o
RE: what plants are impossible to kill

My poor father was at a friends house who was growing a nice little yellow flowered plant in a large pot. He commented on it and then went home with a good sized division.

20 years later the lesser celandine has taken over his entire backyard (Which are all garden beds). He was not a computer user, so he had no way to find out what it was before it was too late. And getting rid of it is physically impossible.. short of removing the top soil. So now every year when it gets warm enough, the entire backyard looks like it was microwaved as all the celandine melts down to mush as the "real" garden continues to grow on.

The few plants I got as divisions carried plenty of the minute bulbs with them ... which then took a few years to eradicate in my garden.

Saponaria officinalis-bouncing bet, it was imported to my garden from divisions of lady fern I received from my mother's garden. I have been pulling it out for years. Another is Phytosegia virginiana-Obedient Plant. another gift from my mother. No matter how much I pull it out it always returns.

RE: what plants are impossible to kill

Lilly of the Valley, it goes everywhere. I dug up a whole bed to pull it out. Turned the soil over and over looking for the slightest thread. Replanted with mature perennials and mulched. By the end of the summer, there it was again.Now I just pull up the pips as I see them like a weed.

RE: what plants are impossible to kill

As new home owners in 1975, planting our first vegetable garden, we fell for the glowing description of 'garden huckleberries' in a seed catalogue. The black berries they produced in meagre quantity failed to make the promised jam or pie, but the plants continue to show up in hidden corners this many years later! There should be a law requiring a 'caution - invasive' label on seed packages!

Same year, a gardening friend 'gifted' us with donations from his garden - goutweed, purple violets, lily-of-the-valley, ozark sundrops, black-eyed-susans, english ivy, vinca. Laughing yet?? Perhaps some time we'll do like Ken and move. Meanwhile we still have remnants of all of the above. Oh - we also planted Boston Ivy - a single plant that has engulfed all four sides of our house. (Free air conditioning!) NO PURPLE LOOSTRIFE though lol.

RE: what plants are impossible to kill

I have to agree on the Lily of the Valley, I practically sifted the soil after digging that bed, still digging up stray pips 3 years later. I've been working on the yucca for 20 years, I think I'm making progress but I dare not turn my back on it. Chinese Lantern. The Aegopodium was easy, the back hoe got it all when the county widened the road.

RE: what plants are impossible to kill

I see someone has already mentioned Bishop's Weed - Aegopodium podagraria 'Variegatum' and Obedient Plant-Physostegia virginiana. I was given some white Obedient plant and during the second year in my mixed bed, it started to come up everywhere, including between rhizomes of my TB irises. That was a lot of fun to dig up without removing the irises. I understand that there is a less invasive Physostegia called Miss Manners that is clump forming and not a runner, and is easier to control.

I had a friend who planted some white Goose Neck Plant -Lysimachia clethroide- because her husband liked it. A few years later she was digging up an entire area of her perennial bed and literally sifting the dirt for pieces of roots in order to rid the area of this thug. It wasn't so cute after while.

I planted some light pink Bouncing Bet a couple of years ago. While I do enjoy the fragrance of the flowers and even the plant habit, I've now spent quite a lot of time digging out the main plant and all the new baby plants that come up from the runners. It's even tried to grow into the lawn, near the area I planted the main piece given to me in a trade. I may try to plant some in a pot and bury the pot in the ground if I decide I can't live without it. There's nothing like the fragrance it gives off during a warm summer evening but keeping it from spreading around is a pain.

Linda


 o
RE: what plants are impossible to kill

Ah, I forgot about the Lysimachia. I helped a friend try to remove it. We dug and sifted, and dug some, resorted to Round-Up at least three times and I suspect we'll be back at it during the coming growing season.


 o
RE: what plants are impossible to kill

Scilla bulbs! -Dug them "all" out many the size of pin heads. The next year, you couldn't tell I removed any at all. -Last year I removed shovels full of soil and got rid of it. -I'll know in two more months......

Lily of the valley for sure. I didnt know about Star of Bethlehem. I just put it in a few years ago, will yank it out as soon as it starts to come up. Thank-you for the tip!!!!!!!!! Tricia


 o
RE: what plants are impossible to kill

I waged a six year battle with goutweed, finally got rid of it. I tried to contain the Lily of the Valley, but it doesn't want to behave, so I'm going to have to dig the whole patch up. Some (volunteer) creeping bellflower showed up in my garden years ago and I'm still dealing with that awful plant.

Be very careful about well-intentioned people who are generous with their plants, these are often the worst invasives.


 o
RE: what plants are impossible to kill

The darn wisteria vine that came with the house! I chopped it down, attempted to dig it up, hacked away at the roots and even resorted to chemicals. The darn thing grew right back in the same summer. Oh well, maybe it will bloom this year.


 o

ivy, morning glory, blackberries


 o
RE: what plants are impossible to kill

I see star of bethlehem has been mentioned *shudder*

Pachysandra. My neighbours & I have waged a decade long war against "kudzu of the north". You have to dig at least a foot down & sift or it will be back. Neither poison nor fire nor tarping will slow it down.

Manitoba maple & Chinese elm. They can be killed, but you need to make sure your neighbours aren't going to call the cops when you KILL IT WITH FIRE!

I patrol regularly for lemon balm & mugwort seedlings (& I do cut the flowering tops), but they are merely a pain, not impossible.


 o
RE: what plants are impossible to kill

Funny thread!

Yes to Lysimachia. I put in just a few of those years ago to brighten up areas next to newly planted spreading jumpers and Karl Forsters. Mistake! I wouldn't say that it's impossible to get rid of, just don't turn your back on it.

Creeping Charlie finds its way into my yard so easily. I guess you can get rid of it with chemical warfare, but I hand pull it.

Oenothera 'Siskiyou', the pink evening primrose, spreads like crazy. It will cover everything in its path.

I guess nothing is IMPOSSIBLE to kill, but it took me a good decade to completely eliminate Ostrich Fern. So why do you ask am I considering getting some of the 7 foot tall Ostrich Fern I mentioned in another thread? Yes, I don't make sense sometimes.

Ivy which is not only in my garden but I am surrounded by it in neighbors gardens. Catbrier, not impossible but it takes it toll in blood. Lesser celandine. God I hate this stuff


 o
RE: what plants are impossible to kill

Calystegia, Tradescantia fluminensis, Hydrocotyle (yes. I planted it...) Ranunculus repens. Geranium robertianum. Any Oxalis with bulbs. Up there with Ornithogalum for pest value - even if the flowers are pleasant.

Strangely enough I don't have a problem with Convallaria. It's been biding its time for years, now, and rarely flowers. Held in check by the Camellia hedge and the Dicksonia antarctica, I suspect.

Yarrow is another struggler, for me. It doesn't like heavy applications of compost or mulch. Tends to rot out after a while.


 o
RE: what plants are impossible to kill

I bought a house about 18months ago. It was late fall when we moved in. Spring came and we found we have multiple large beds full of mixed Lilly of the Valley, English Ivy, Latium, and vinca minor. I started methodically digging, but I may have to retire before I'll have enough time to get ahead. Fortunately, they are at least attractive, so I don't hate the yard. Actually, the LOV smells heavenly in the spring. We probably have about 1/4 acre of solid LOV, so when a little breeze drifts by the fragrance is amazing. Happy weeding!


 o
RE: what plants are impossible to kill

Ken-
For some reason I thought this thread might go along a different stray path ... the path of zen violets.

On the violet front I had my epiphany in November.
I had carefully dug violets out of cracks, crevices, crannies, and crab shells. Okay, there weren't any crab shells in my garden. I just went a little overboard with the alliteration.
The violets that had me assuming the ancient garden weeder position -- head down, tail up -- were enjoying a gravel path along the side of my house.
One of these days I might hit the jack pot and re-do this path "properly". (um, doubt it.) In the meantime it's a national weed preserve. Then the light bulb went off. The violets ... oh, yes, the Garden Club sells them every year and so does the Native Plant society chapter. I mean, come on, these are plants people buy and I'm pulling them up when they are doing a job I had just started contemplating buying something else to do, i.e. ground cover. They do a reasonably good job of smothering out weeds that are way uglier.

And, since violets aren't among the so-called steppables, as soon as I re-do this path with violets filling in here and there, they will probably keel over and die. Guaranteed eradication technique. Breathe in, breathe out, visualize the path with violets handling a tricky situation in a special spot. The violets will immediately begin to look peeky, leaves limp, yellow, croak.

Either way, dead or alive, I'll be happy.


 o
RE: what plants are impossible to kill

Wellspring, I've used violets in a path before too. In general, they don't transplant well, but once established, don't mind being stepped on - moderately. I'll never stop thinking it's ridiculous that people "go along" when they're told it's a failure if these weeds native flowers are growing in one's lawn.

RE: what plants are impossible to kill

Just came in from digging up a huge wandering patch of physostegia virginiana "Vivid". The seed packet said it was a less invasive variety- HA! It's a nightmare. Ditto anemone tomentosa "Robustissima" (grapeleaf anemone). I was a new gardener and thought "It's robust! That's what I need, I can't kill that!" Sadly I was right. It's awfully pretty in the spring though.


 o
RE: what plants are impossible to kill

Oops, meant to say the grapeleaf anemone was pretty in the fall, not spring. Digging out obedient plant has addled my brain!


 o
RE: what plants are impossible to kill

Creeping bellflower-is-IMPOSSIBLE. Glyphosate only slows it momentarily. digging it out it will regrow from root bits, andit sets tons of seeds. plus it invades your shrubs.
.....because your neighbors dont know what it is -even if you sift all your dirt and work 6 years to keep it gone, when you turn your back it creeps right back. Takes over lawns, beds everything.


 o
RE: what plants are impossible to kill

I agree with violets. My neighbor has some in her garden and I have it everywhere. So far, it's staying out of the gardens for the most part, so I'm just going to leave it.

I've also been fighting with milkweed. I don't know if the people who lived in our house before us planted it or if it just took off from neglect, but I had stalks almost three feet tall in the back of my house. I'm *very* allergic. Last summer, we screened the dirt down a bit more than a shovelfull deep and it still came back. Hopefully our cold winter killed it (ha, ha).


 o
RE: what plants are impossible to kill

We actually managed to get rid of my parents yucca/century plant (I was never sure, but it may be the latter). I coated the roots/tubers with straight Round Up. It still grew back a little, but dad's friend dug it out with a pick axe. It hasn't come back. Yay! Unfortunately, it did kill a tree that dad really likes. :(

I cannot seem to grow lily of the valley well...at least, it is not poking up yet this year. (Crosses fingers)

RE: what plants are impossible to kill

I made the mistake of planting northern sea oats under a shade tree. It was beautiful and not a problem until the tree died and the area became sunny. The sea oats started sprouting up everywhere. It would come up all around and intertwine the roots of shrubs. It was impossible to pull and hard to get with Roundup. I had to cut the seed heads as soon as they appeared and no longer got to enjoy the plant. Sure glad I moved from that property!


 o
RE: what plants are impossible to kill

Lily of the valley. It's been here a LONG time and I imagine despite my best efforts, will continue to be. The wisteria won't go away, even though we cut it down last spring (and mow over it every week in spring/summer/fall), it's still sending up volunteeers. Quince. I'd trade more creeping charlie to have that thing behave.

Field mice tend to take care of obedient plant-I have yet to see it make it to flowering. They mow it every year. I've decided to leave some, so they eat that and leave my other things alone!

 o
RE: what plants are impossible to kill

For me it has been dill. I planted it by my back door with other herbs. I failed to keep it from going to seed. Well its everywhere this spring. It just keeps popping up. At least its easy to pull. No one could use all of the dill I have growing!

Lola-lemon you mention creeping bellflower. I received one from a plant swap this year. It sure looks innocent enough. Should I rethink this? They never mentioned that it was a bully in the garden.


 o
RE: what plants are impossible to kill

Well, I have the violets but they are so pretty I don't mind. For me, nicotiana and larkspur, yes, they are both lovely but I have not planted them in a few years and yet I always find many, many seedlings. Rudbeckia goldsturm, I tried to remake the bed these were in, every year keep pulling out bits that I missed and they still come up. Again, I do like them but getting rid of them is not easy. And most of all, yes, scilla is bane of my garden! I planted some 20 years ago, every year I pull out more and more it just never stops coming. I do like my lily of the valley, they do spread but not too much for me.

Ditto the violets--even heavy cardboard topped with several inches of bark mulch doesn't begin to slow them down. I've spent the past seven years trying to eradicate them--even painted the individual plants with vinegar and they still come back the next year. Vinegar generally kills everything but it hasn't killed the violets.

Lily of the valley is another thug--I actually asked my neighbor to come with his backhoe and dig them out so they're mostly gone now. Do I think they won't show up again? I'm I a gardener... I KNOW they will...it's only a matter of time.


 o
RE: what plants are impossible to kill

I'm curious about the violets everyone is talking about. I have Canada violet that I let be. It has filled in in spaces where I don't mind it growing, like under the deck and under the rose bush. Right now it is blooming and looks very peaceful to me. It is a wildflower or weed depending on your point of view. I have had it for many years and it has spread, but not to the point where I'd consider getting rid of it. If is seeds into the patio stone spaces I give it a squirt of round-up if I'm so inclined.
But don't get me started on creeping charlie and ox-eye daisy!


 o
RE: what plants are impossible to kill

dspen,

Creeping bellflower is a horrible plant; you can never get rid of it. I didn't even buy this plant, it just appeared one day and grew into my daylilies. When digging it out, you need to sift through the soil and get rid of any traces of roots because those pieces will become a new plant.

Clustered bellflower is not much better. I do have the peach-leaved, which self seeds like crazy but seems easier to pull out. There are some really nice, well-behaved, bellflowers but you really need to do your research.

RE: what plants are impossible to kill

I agree with you, mxk3, violets and dandelions are lovely beneficial plants. I cannot understand why anyone would want to be ridded of them. Both make our lawn and meadow look like a magical paradise, and dandelions are nutritious. Our horses grazed the meadow all their lives and benefited from the vitamins, eating foliage and yellow blooms alike. I pick dandelions and add them to salads and stir fries, sometimes cook them like spinach. Get rid of these flowers? I think not!

Bindweed is a challenge to eradicate as are burdocks and wild (poison) parsnips. All one can do is keep them at bay by cutting and pulling.

I have a love/hate relationship with blackberry brambles. I let some grow to harvest the fruit, but keeping them from overtaking the whole property is a constant struggle.


 o
RE: what plants are impossible to kill

Here's the thing about violets. IF you just had a lawn, they would be one thing. But, violets in particular, will invade beds in the deepest shade or full sun, around here at least. And both are probably allelopathic, so they are slowly killing your other plants or at least keeping them from growing well. I had an asarum that was surrounded by violets and was barely growing at all until I rooted them out with a fork. (you can't just pull, they snap)
Judicious use of pesticides can control any serious weed, and I think people's reports of "oh, it's impossible, the thing is resistant to XXX" are often because they aren't formulating or applying them correctly. One of my worst weeds is Smilax, but I've figured out that you can kill it w/glyphosate if you use double the surfactant, add a tablespoon of ammonia, and increase the roundup. (actually, the concentration recommended for brush anyhow, 5 oz per gallon of the standard commercial 40% product)
The closest to being truly resistant is thistle, not because it has actual resistance per se (though I have no doubt that out in the midwest some clones do) but just because it is tough and taprooted. Still, 3 rounds of anything well applied will get it.
For vines and trees is far more efficent to cut them at the base and apply a cotton swab, covered in foil, that is dipped in 50% glyphosate/water/few drops of detergent. (so, 20% actual concentration) Never seen anything survive that, though a tree over 1" caliper might need a couple cotton balls and you should use a twisting motion with the loppers to loosen the bark. For the same ounces of roundup that would make 2 gallons of spray, you can kill many, many trees seedlings or vines with no overspray, less ugliness of dying foliage, and less waste of chemicals that you otherwise would.

BTW although selectives appear to kill violet and creeping charlie faster, if you don't have to use a selective, the high strength version of roundup actually kill them more thoroughly. It just takes 2-3 weeks until they finally appear dead, versus 1-2 days with the selectives. Just be sure to add enough surfactant, the leaves of violet have a waxy coating.


 o
RE: what plants are impossible to kill

BTW I planted the variegated lily of the valley specifically with hopes that the weakness caused by variegation will slow it down a bit. We will see.


 o
RE: what plants are impossible to kill

I have violets taking over. I thought they were pretty several years ago. Still do, but they are everywhere now and growing huge! I did read that they are the host plant for many Fritillary butterflies, so I plan to leave the ones that aren't in the way of other things.

From the North America Butterfly Association:
Importance as a caterpillar food source: Fritillary caterpillars are often divided into two groups; Greater and Lesser. The Greater Fritillary butterflies are larger and the caterpillars feed exclusively on violets. The Lesser Fritillary butterflies tend to be smaller in size and while they use violets as a caterpillar food plant, they also will select other host plants such as passionflower.

So, that just makes me feel better about having let them all go! I plan to go pull out the Lilies of the Valley that I planted years ago and which are just now looking as if they are starting to spread! Thanks!


 o
RE: what plants are impossible to kill

The ones that cause my blood pressure to skyrocket, especially when I see them for SALE at the garden centre are vinca, red-veined sorrel, mint, wild violets and gooseneck loosestrife.

My battle with mint has calmed down over 4 years. Now there is just enough that pops up for me to actually use in salads etc. The gooseneck is another story and I wish I'd listened to people here. I got completely seduced by their beauty.

My compost/dumping ground is quite pretty right now with random growths of chives, huskers red penstemons, magenta cranesbill and ... vinca.


 o
RE: what plants are impossible to kill

Agreeing with several already mentioned, Yucca, Yarrow, violets. Also bindweed, which is all over our yard, and the orange ditch daylilies, which are very aggressive spreaders.


 o
RE: what plants are impossible to kill

You wouldn't want Vinca anywhere near a perennial bed, but for a shady shrub border, I can think of much worse things to deal with. The competition: ivy, poison ivy, boston ivy, grape vine, Smilax, Lonicera...will all twine up into shrubs. Vinca does not, at least for me.


 o
RE: what plants are impossible to kill

dspen don't do it! It's horrible stuff.
It is virtually unkillable. I am not kidding. Chemicals just slow it down and because it creeps underground (easily crosses under full sized county sidewalks) and loves to pop up inside mature shrubs (hides its dang roots in good plants root crowns) there is basically no way to remove it without killing everything else (and it'll probably still come back). I dug it out of most of my beds, but there were enough root bits left in the shrubs, that I still have to weed it out twice a week. it makes black medic, bindweed, gout weed all seem like tender annuals.....

it takes over golf courses- which are heavily sprayed and mowed! My neighbor nuked his whole lawn and had it resodded-- but still the stuff came back.

If you let it go for a few years, I doubt you will ever get rid of it. Ever. I mean that with total sincerity. And if you don't weed it religiously, it will out compete everything else.

Ditch Lillies!!! I hate em!! Everybody in the friggin development has em. Must have been a part of the developers grand landscaping plan. Previous owner even sowed them in the backyard. I had to bring in the pros to get that under control. And still a couple of years later, I have to walk judiciously with my round up paint brush. A whole side of my house is planted with them. And the mailbox. I'm waiting until Fall to take those areas on. I like lilies. Asiatic lilies, really pretty day lilies. But the dreaded ditch lily has got to go......Grrrrrrrrrrrrrrr

Algerian Ivy and Acanthus Molis. Each took a number of
years to vanquish. I finally rid my garden of both but as far as killing them? Digging out is all that worked.
I am in my second year in my campaign against bindweed. I am happy with my progress but I expect it will be a few more years before I declare victory.
I gathered seeds travelling through Nevada and planted them when I returned to California. It was the invasive Saponaria you speak of. Luckily a veteran gardener I know told me it was a bully and I got rid of them in time

Just reading mzdee's post about ditch lilies makes me laugh. There used to be a landscaper in the suite next to the office where I work and last summer he had a full truck load of ditch lilies, ready to take off to a job. I just thought "really?". Someone obviously didn't realize you can pull on up off the side of the road, throw it in the yard and you'll have an endless supply in no time. I have a ton in my back yard (came with the house). There's on particular patch that gets abused to no end... the dogs trample them, role in them, dig at them... And I have two pits and a husky so when the dig, run and role they REALLY go for it lol. These things barely even notice lol

False lamium... I have it creeping under the privacy fence from the little woodsy area behind the house. It looks pretty in the pure-shade corner with the lemon balm. I just sigh when I look at it all in all its thug-glory

Hops vine and bindweed are my big banes. You never, ever want to plant a hops vine near a garden. Trust me on this! The wild scentless violets are getting a bit thuggish too. I've also spent a lot of time recently cleaning wild blackberry vines out of my day lilies, though I must admit that I left the ones that actually had berries on them.
