Thank you to everybody for your messages and for your help.
I them you that around here in my residential have more plumbagos planted but are with white flowers and not very attractives for me, I prefer the sky blue flowers.
But her I will place photos of the all plumbagos for that you can look.

Hi
Is a very common landscape plant in s. florida (U S) Comes in red white and at least 3 shades of blue .
Can't imag ine how it would grow in Colombia !!lol Very rampant I have 3 patches over 10 feet in both directions with constant pruning. IT does stay in flower year around
no pests and I love blue flowers!! lol
Have never tried to propagate it as it's very common in nurseries here .. Pick an area where the is enough area to expand against a fence is good. gary

After the late season freeze (Feb) and record breaking March rainfall the PNW experienced. I am not surprised that many plants have taken a big hit. In my role as a garden consultant, I have seen all manner of even very hardy plants bite the dust this season. The combination of a pretty mild winter and the early end of dormancy for a lot of plants followed by a 1-2 weird weather punch was just more than they could handle. Couple that with hollyhocks' typical short lifespan and I'd think it was time to replant with fresh plants :-))

Yes, I was surprised to see that they had a thin tuber..Shaped kind of like a dahlia. I believe, but would not swear, that I bought the double mixture from Costco. I am going to be patient, and maybe dig up around in there and see if there is any sign of life. They got to be 8' or so tall, and very impressive. I used Bayer Advanced disease care when they got RUST. They were gorgeous. Will keep you updated.


laceyvail, I wouldn't dig them up just yet, just cut back if you can't stand looking at it. 10 yrs is very established. The cluster of tubers underground are probably OK, some of mine got quite a bit of winter scald so the leaves aren't what they usually are but they are just now putting out new blooms -- no new leaves of yet here a bit further south, they do that later.
If they got too wet however, they might have rotted. You can sometimes tell by your nose with a bit of probing if thats the case.

In my gardens, Arabis foliage has always looked a bit tattered in summer, while Iberis (both Autumn Beauty and a couple other kinds I have forgotten) look better. I don't know if it's where I have it in only about 4 hours of sun, but Autumn Beauty has a less nice plant form, floppier than the other Iberis I have grown. If I were to do it again, I would get a shorter, spring-only blooming Iberis rather than Autumn Beauty which has spring and fall blooms.
I don't know what Arabis doesn't like about my growing conditions, since this is the second garden I've had where it's languished in full sun and well drained soil.
I have quite acid, fine sandy loam in this garden, and where I have previously grown Iberis was in acid loam, former farmland. Where I previously grew Arabis was at the top of a rock wall in well-drained rocky loam.

I was just cleaning up a bed today that is edged with Autumn Beauty, and I am considering removing it. It is leggy and floppy, no matter how much I cut it back, and the bloom is rather sparse. It also didn't do too well over this past winter, but I am not holding that against it - lots of things didn't do well this winter! Perhaps it's not in the right spot, but I am not overly thrilled with it. The foliage is pretty and in bloom it is lovely, but the form leaves something to be desired, IMO, and the bloom is not nearly heavy enough to make up for it... even though those few sporadic blooms in fall are precious... I may look into a different variety, because it is a pretty plant in general.
I have some rockcress in the very first garden I planted years ago, which is now very neglected, I'm ashamed to say, and the rockcress has spread quite a bit. I guess I wasn't aware it was a groundcover. I don't dislike it; it is a nice little groundcover with pleasant white blooms. But since this bed is neglected, I can't give a really accurate account of it since I haven't paid much attention! Obviously it is hardy, spreads well if that is what you want, and thrives on neglect, lol. I plan (ha, ha,) on renovating this bed this year so I may take out a lot or at least move it off the walkway, which it completely covers at the moment.

Well I cut them all back to about 6-8" so now just so watch and wait. We just had a ton of rain over the earlier part of this week so my beds are pretty wet, but no standing water in them at least.
TexasRanger thanks for the sand suggestion, but I think I'll wait and see how it all goes. I've heard conflicting stuff about sand and clay soil so for now I'm just making sure we till some composted manure in any new beds although it probably wouldn't hurt to use it as a yearly addition to the top of the beds too. Hopefully they'll be as big as yours someday.
Thanks again for all of your advice, everyone!


It really shouldn't matter if these are purchased bare root or potted. I also think it would be difficult to find these mail order as bare root plants. I've never seen them this way.
I suspect there's another reason your potted ones didn't survive. Possibly the time of the year you purchased and planted them, were they dried out in their pots for any length of time, were they watered adequately when you planted them, etc. etc.

Do NOT wait until Fall. It's tricky to store bulbs that long without killing them, particularly lily.
The Daffodils may have a papery covering. The lilies will be scaly. The two of them can probably cohabit fine. (The daffodil blooms early and goes to sleep). The monkey grass is the thing you have to be careful to get rid of if you want the lilies to survive.

though it is only marginally perennial in my area (zone 6), I have been using Verbena canadensis as an annual here. They are typically sold at a nominal price....they are perfect for the cascading wall effect.. they bloom heavily but aren't a single blanket of blooms... a single plant can spread nicely within a single year.. blooming continually until the fall... and they don't need to be tended at all.
They will root down where the stems touch the soil, but are very easily to pull up after the fall or in the spring. And they come in a few color varieties.

lacyvail,
A bit late! Last year I planted a couple of Rozannes, which I believe are Geranium Sanguineum. I thought they spread by rhizomes and the seeds were sterile? I didn't expect them to shoot seeds all over. Guess I will have to keep my eyes open for that.
My other geraniums are Biokovo, and I love the fragrance of the leaves!

An unusually cold winter + Ruellia could well mean no plants this year in zone 6.
If whatever species/hybrid it is is marginal in z. 6, it still might be worth trying again.
I never found Ruellia hybrids to be especially thuggy in the Gulf Coast region, but maybe that was because I was battling other thugs (like Passiflora "Incense", which was capable of submarining under sidewalks to pop up in new places).

I love this plant, but am about to give up on it because it has to be confined to a container due to a lack of garden space and its running tendencies. If it didn't get so huge, I'd just let it run. Container growing is fine for year one, then it gets so pot bound that it requires watering every day, even though the base sits in a saucer of water. The real difficulty is that splitting and repotting mean all of the old soil and roots need to be disposed of in the trash. :( I hate the waste. But I can understand your wanting to have this plant growing in your garden, njdevil. There is something special about those flowers.

No. Spring fever hasn't hit me yet, although I did buy seeds; my annual, vegetable, and herb seedlings are coming along quite nicely. I've also been busy fixing up the inside of the house - definitely in the buying mood for the house :0) Plus, I'm so overwhelmed with cr@p to do in the yard (since I left a big mess in the fall), I have all that to deal with - part of me is looking forward to getting to work out there while another part of me is dreading it. I plan on starting to tackle the clean-up this weekend.
I'm sure when the weather finally warms up and it's time to hit the nurseries for the yearly annual-buying binge, I'll be all gung-ho :0p

Over the winter, I didn't get to look over catalogs or update my journal or think a lot about what I needed to do this year. And so I've been playing catch up for the past month.
Last Fall, I decided to redo a few areas and put in an order for roses. The nursery sells out quickly so I had to put the order in early. I'm still trying to find disease resistant roses and keep trying a few. And that was the extent of my ordering until March when I had to order vegetable seeds.
When you order roses you have to choose a shipping date and you're supposed to get the barefoot roses in as early as possible, so I chose the last week in March for a shipping date. They came the day we had a week of freezing temperatures and I still had snow on the ground. [g] So I had to keep them in the refrigerator for 10 days before I could plant them. But they are doing great and I'm amazed. I thought for sure they were not going to make it. So that's exciting.
I did go shopping last weekend in that dreary cold rain we had, and had the nurseries all to ourselves. Brought home a few shrubs and native plants. One of the fruiting Sambucus which I am also excited about and have been trying to find one for a couple of years. And tomato plants that I didn't get started in time, that are now sitting under lights until the weather warms up. What about July maybe? :-)
Seriously, this weather has to change soon, right? Every week, I say to myself, this is the last week and the week after that it's finally going to warm up. As soon as we get a sunny week with temperatures in the 70s, we'll all be a lot more excited and motivated!


Anemone Robustissima has spread all throughout my perennial bed and gravel paths. The first year it looked so grand, clear pink flowers swaying in the breeze. Now I am constantly trying to pull it out, but it conveniently breaks off at the root and re-grows. I have a few of the others people have mentioned but they have not gone crazy yet. YET. I am trying to get crocosmia to put on a show, but the place it is in gets dry and hot, and I don't baby it. The other one I have is Major Wheeler Honeysuckle and some other red/orange honeysuckle that was popular last year - the name escapes me now. Both were vigorous growers but I just kept pruning them to the space I have allotted for them. They are playing nicely (for now) with a purple clematis and a deep pink John Cabot rose, all trained on the fence that is a backdrop to a driveway bed/hellstrip. The things I do for those cute hummingbirds!!

I haven't grown it here in OK, but I DID grow it when I lived in CO. Yes, it will appreciate good drainage, and due to the humidity in MN, I would opt for a very sunny site as well. As far as temperature, they are hardy to quite low temps and the foothills of the Rockies are not necessarily snowy but can be extremely windy and drying. However, they may not survive ice well, which the base of the Rockies does not usually get. Once it is well established though, it should be quite hardy in your area. You might want to make sure to cover it in the worst winter weather the first year or two.

Hi KSimS,
Very attractive.
Love the colours.
That business about blue/purple and the camera:
I don't know much about photography, but got a new camera a while back. Started using it this spring and had a fit when the purple crocuses appeared blue in the pictures.
A friend pointed me to the "white balance" function on the camera. Turning it from White Balance Automatical to Daylight, for garden pictures, is currently solving the problem.
Thanks SunnyBorders! That is very helpful concerning the camera and purple blue issue. I will definitely have to check the settings.
