...I just posted on another thread, that Persicaria 'J.S. Caliente' is not hot for me... and it should be, that's what I was expecting and I'm so disappointed.... I've been looking forward to these all winter...
...Rudbeckia 'Deamii' is another that I'm not sure I like too much... lots of yellow daisy flowers but this and 'Goldsturm' I think are maybe not to my taste... whereas 'Henry Eilers' I'm liking very much..... bit different that one...
...Hot... Helenium 'Rubinzwerg'... and Aster 'Monch'... but they're well known in any case..
...Pennisetum 'Karley Rose' was slow to get going but it's taken off and I'm liking this one too...
..I also have Aster 'Wunder von Stafa' a sister seedling to 'Monch' and got this specifically because it flops and that's just what I wanted for its position.... I've had this before and I love the colour and graceful nature...
...Sedum 'Matrona' is just gorgeous too, but that gets the Chelsea Chop in May... a must for this plant I find...
..Stipa gigantea is always a show stopper.. I can't be without it, also Festuca 'Elijah Blue'... and Miscanthus 'Kleine Fontaine' which is just coming into flower right now... a most elegant weeping form...
...Petrorhagia illyrica 'Pink Starlets'.. I think that's the variety name.. is fast becoming one of my favourite ground coverers, underplantings.... it's just finishing now, been in flower since June... rather Gypsophila like.. dainty sprays of little pink/white flowers on a spreading plant...
..and finally, my hottest of the lot... Geum 'Blazing Sunset'.. still in bloom, since May, and I just love this blazing Geum with my roses, grasses and everything else to be quite honest....
...sorry cat, got carried away...


Such a nice thread, I like Helianthus as well.
@campanula: only reason I could think of is too much rain?
My Lemon Q I got from neighbours at the alottment, plonked them in the ground, hardly any TLC, and even in the next dry year they thrived.
now we had a terribly dry hot summer, some of the few things not bothered at all are the increasing clumps of LQ, growing through dry spells of 4weeks without rain.
my soil is heavy, "well wormed" and with a good organic part due to mulching every plant bit instead of composting it.
and I need to look for those other cultivars,
have a nice weekend, bye, Lin




Mine has looked like this since mid July here in central Oklahoma. Not much Pow Wow for the buck in our hot summers. Like I said, its thirsty and doesn't seem to like the heat down here. It punks out early, did the same thing last year but yes, it survives winter. I'm sticking with the unimproved types, no molly coddling here even though I have taken pity on it and watered it every week since I have a salvia close by I'm trying to get established. Otherwise, even the foliage would be toast.
Since we are asking how'd they do.....I give it a low rating. To be fair, I have just about come to the conclusion that your summer further north is like our spring. These don't do summer here, down here I consider it a spring bloomer.


It wouldn’t be invasive around here, lol. It’s taken 6 years in the ground to get the 3 feet spread I have now. I have never seen an ivy bloom, not even the hoary old ones I take into the house for the winter, so no seeding here either.
Though considering the slowness of growth, I might be better off finding some of the dark green variety commonly sold as ground cover here. By the time I was more or less ready to plant this area, however, I couldn’t find any in the stores.

I justr looked up the name....Hedera helix Canariensis is Algerian ivy, with a much bigger leaf. I have that in some other pots. It is much pickier and harder to grow and root (here). I can't get it to branch readily by pinching the way I can the others. I like it, I wish it was easier. The white edged one has leaves no larger than one inch, most smaller.

I know asteromoea mongolica was reclassified as kalimeris a while back, but I'm still confused on whether or not it is also the same plant as tanacetum parthenium? I gave a like to a gorgeous photo of tanacetum parthenium posted by Pitimpinai and put it in my wish list ideabook to remind me to get some, thinking it is the same plant that I planted a year ago labeled as 'asteromoea mongolica' which didn't survive. Am I confusing two entirely different plants?

rouge21 -- I've had this plant for a decade or so and I love it. I'm in MA so it blooms in Aug-Sept for me also. Nice delicate look, airy and dainty. Mine is somewhat of a spreader, tho not aggressive IMO and easy enough to yank out when it gets the urge to go where I don't want it. On the other hand, yours looks more like a single "bush" than mine, which are basically many single stems growing next to each other. Maybe I don't have what you have after all, but the bloom is the same and the leaves. Now I am very confused. Which is not unusual, LOL.


Are mine the only ones that do not clump and form a mass such as rouge21 shows in her photo? I definitely have Triloba but individual plants are quite delicate albeit tall as I am usually (5 feet). As they are scattered here and there throughout the gardens, they are not obstructive of the views of the rest of the plants at all...

Sympathies, Raestr.
I'm not a lover of spiderwort, in part, for the reason Nevermore says. Still I too have, in the past, planted several spiderwort cultivars which did not seed around at all. It's a native plant, but I'm assuming some of the cultivars have been selected as sterile or non seed-producing.
As said, we had a problem with a neighbour and his buckthorn tree (prolific seed production and distribution (latter by birds)). Of course, he was unaware of any problem at all. Still he was quite happy to allow us to pay to have his buckthorn tree removed.


Thank you all for the comments. I actually do not know how deep the soil is although I'd be surprised if its too deep. I've only transplanted small annuals before so I'm not really sure. I could always add more soil. I added black eyed Susan at a different location and something is eating them to death! Maybe it isn't deer but even the deer spray doesn't seem to work too well. Bottom line is I am frustrated and not overly pleased with the perennial choices I have around me. Maybe this fall when the nurseries have a big sale I can see what they have then. Like I said this year the vinca did really well but that's a lot of flats every year for all that I have to plant.

If this is a summer house then you want tough plants, because presumably you may not be there to water them. I like echinacea for easy summer blooms. Baptista Australis likes rocky soil, although it is a spring bloomer. Also liked the liatris suggestions,





I'm not sure what differences you are seeing between the two.
Agree - tansy. I like the foliage.
