Yes, it's Plumbago auriculata. Carrie, when you overwinter yours do you try to keep the tops growing and green or do you let the whole thing go dormant? Do you keep it in light or dark? The plant is kind of expensive to me, so I want to learn how to overwinter mine. Last spring I bought a big plant of it, divided it in three, and then took cuttings. The cuttings were slow to root but ended up making good sized plants.
Thanks,
Linda

I'm bumping this. found 4 of these plants at Lowes on clearance for $2 each. Bought w/o researching first as its fun! Anyways do you think I can grow these fine in Evans/Augusta GA? Hotter than hell now. But my plan was to rid myself of some KO roses that are thin and not doing much. I over bought and now I'm sick of them; so the Plumbago's will be going in a nice mound and I will space them out and hopefully keep them around 4'. But they are little now. I guess if they are going to die if we have a few cold snaps I dont wanna go through the hassle. Thanks.

Pretty Mary! I do like the darker colors better. Yes please let me know if you're able to collect seeds from it this summer. I would love that.
One of my seedlings from a packet of 'Gay Butterflies' that I wintersowed last year is about to bloom for the first time, but it looks like it's either going to be yellow or very light orange darnit. There are three others that are smaller. I'm hoping they'll all bloom so I can see what color they are.

Depends on the specific product but by and large, no :-) Most contain some sort of growth hormone, some have B1 and other nondisclosed and rather mysterious additives (that may or may not do anything) and some are just a root booster fertilizer with a higher concentration of phosphorus, often sold as a 'starter' fertilizer.Of any of these I would opt for the starter fert first

Wow, gorgeous! Thanks for sharing this! My lupines (only blue/purple ones) are really doing well this spring and I have been enjoying the new (for me) combination of them with my irises this year. These photos make my small bed look a bit pathetic, lol, but at least I know I had the right idea in mind!
How did you leave there only buying a few things? You must have some pretty strong willpower!
Thanks again for posting this. It was really enjoyable!

kill it now.. it is INVASIVE.. and if you let it seed.. it will take over..
i have lived here for 12 years.. and i am still trying to kill it..
those seeds must have a half life of a bazillion years ... because i try to never let it go to seed ...
its a nightmare..

i have a plethora of columbine in near full shade.. the deep purple ones that reseed freely.. not the foo foo kind ...
being biennial at best.. if this is the flower year... i dont know if its worthwhile ...
and mine are already losing the flowers .. in the drought and heat ...

I'm not sure which plant you mean by Rock Cress - could it be Aubretia? In which case I can't help you with the seed germination question except to say, if it is Aubretia the seedlings might not come up the same colour as the parent. it tends to revert to its native mauve.
As for dividing it I can't see why it would need dividing after just a few months. Aubretia looks good left to form big cushions two feet or so across, especially if spilling over a wall. It would rather defeat its best feature IMO to divide it into prissy little clumps. It retains its form best if clipped over with the shears after flowering.
All this is predicated on my having guessed correctly what you mean by Rock Cress.


I too saw one at a nursery. The blooms actually looked really nice.. but they had most of their plants under a pretty dense shade canopy. So I would assume that the bicolor...ness can fade out and have it end up being just plain purple looking like Ech..manic noted.
They also only had the single stem growth with bloom on the top (not branching at the base).. so they wouldn't make it through the winter here.


That is Agastache hybrida 'Acapulco Trio'. I got them at Lowes last year for a dollar on the clearance rack. There are 3 colors together...orange, red, and a light purple color. They are one of my favorites. They root from cuttings very easily.


For ONCE I had all the plants I wanted to pick up in the Bluestone sale ready in my wishlist so ordering was a breeze.
Got them yesterday and it's gonna be 90+ for a week.
They may just stay in their little pots in the shade until this hot spell passes on next week.

Definitely a shurub, I think. Unless this is a perennial-only garden. Clethra makes a nice native shrub choice for part shade. Otherwise, you need tall wildflowers. Aconitum napellus if you dare...it is very poisonous but looks great in late summer.

thalictrum. Esp if astilbe is real tall, like ostrich plume or ....can't remember the other one....
But it really depends on the astilbe....some are only a foot high and have bronze foliage....the gold hakone grasses are gorgeous with those; so is trollius gold queen; some have red foliage, some are 3 feet tall....no one size fits all.




alfalfa is a growth stimulant .. i cant remember the active ingredient ... it was all the rage in the hosta world.. a decade or so back ...
and frankly.. its the mouth end.. of what come out the back of the horse.. undigested ...
it is also rabbit food .. and the one time i spread it ON TOP.. i attracted rabbits.. who got really pissed off.. after it was gone ... and started eating the garden .... many would call that a rabbit LURE ...
plus the idiot golden retriever ate a bunch.. and had gas worse than a horse that night..
incorporate the granular.. if you wish.. but dont leave it on top ...
MANY peeps use to to brew a tea.. and use that to water.. you might try the search function and relate the words to hosta.. and see what you get ... try the link

Yes it attracts rabbits and it's high in nitrogen. Not a replacement for compost.
