There is no way that a Jackmanii Clematis changed to Miss Bateman.
The shape of the blooms and the leaves are totally different.
Simply impossible.
The one on the right is not Jackmanii either.
There could have been blooming Jackmaniis in the pots but to have two with two planted in the pot with the same one dying off is a very slim chance....

The explanation for the echinacea is not hard to understand. The recent colored hybrids all have E. purpurea in their parentage, together with several other native species. And it's been pretty well-established that many of these are not necessarily stable hybrids and various cultivars have experienced all manner of uncommon or unnatural growth. The plant just reverted. Reversion from hybrid to one of the parent species is not an uncommon occurrence in horticulture.

Mine never flopped and it was very lovely. It was the only Stokes I've ever had, and from its habit I never would have thought they tended to flop - it was THAT upright! Unfortunately, I think I had it in a place of too much moisture in spring, and it only lasted 2 years. Very long blooming...as dry as it's been here I've been thinking about trying it again...

THANK YOU EVERYONE! Gazania... that is beautiful! The one I have in front never looked like your first picture of purple and green (though now I wish it would... it looks amazing!) but it did go through the green/yellow, to the darker reds, burnt oranges and browns, etc. Actually the picture I posted is probably from April or May. The one in my back yard looked like your second picture and then the yellow faded to all green. Thank you all so much! And love the method to remembering the name lol... I'll need it!

they will bloom eventually, and when yours do, they will be magnificent. It sometimes happens that they just don't make enough growth during their flowering year, putting all their energy into making a massive rosette of leaves - in which case, they will bloom the following year (when they will be enormous). Generally, I sow biennials during the early part of summer so they have a few months to get to a decent size before their first winter - they bloom the following summer.

I've had Sentimental Blue for many, many years and have many, many established clumps of them (makes a beautiful, tidy edger). A few additional another flower heads will pop up here and there post dead-heading, but they are not really considered re-bloomers (at least not reliably). Once the main flush is done, that's pretty much it for the most part, I view any additional flowering as a bonus :0)

When I first bought mine the nursery employee told me that they r picky after transplant and will bloom better the following year (which they did). I think you just have to have patience, in the following years just continue to dead head spent blooms. Mine get prettier every year and continue to bloom when deadheaded.

I believe it probably is Silene armeria unless of course there is another similar Silene species I'm not aware of.
This was something my grandmother grew. Because she allowed everything to self sow wherever they wanted to, she had these by the thousands. To say they are prolific is an understatement.
I had them in my garden for a few years and then decided I didn't like the hot pink flowers. I pulled up every seedling I found, but they kept appearing for years afterwards. The seed heads are like vases. When they are dry, just tip them over and seeds spill out like crazy.

Am I gonna lose all my P-Cones this year & have to star over? I suppose I can't even save seeds huh? Do I dig to destroy or can I cut to the ground & use round-up on the left cut stems?
As I mentioned in the other thread (w/ the same question) ~ we here are plagued w/ another year of Jap Beetles & although they don't particularly eat P-Cone tops I've found a few on them in transit to their favorite rose blooms.
Appreciate your experience & thoughts!!! TIA

I suppose you could use roundup.. but i would pull the whole plant to make sure you get everything.
The virus is transferred via leaf hoppers... so it's just luck in regards to how far it may have spread to your other coneflowers (rudbeckia or any other asteraceas). I would just keep any eye on the others.
I am seeing asters yellow at every single Lowes and HD in my area with their coneflowers. Even true garden nurseries have plants with it. It is everywhere.. and will only spread more with them selling these plants on.

I found the linked study informative. Their 'Sentimental Blue' got 12 inches tall. Mine are about 10 inches but they tend to lay down a bit, making them appear shorter. Their 'Mariesii' cultivar was disqualified because it was mislabeled. Seems to be a common theme with these.
Here is a link that might be useful: Platycodon Cultivar Comparison

I planted both Sentimental Blue (short) & (tall) Shell Pink 11 years ago ~ I have them every where now as they do seed (if not dead headed).
SB seem to behave differently in the different sites I eventually planted them from seeds. I have one that is enormous (2ft) both in hgt & clump & others stay as low as 8" others even showed up pink balloons along w/ the blues!
Shell Pink, I call Vanessa in honor of an Angel, stayed true to her tall, elegant lady that she is! Has also sprouted seedlings I have shared & planted in other beds.
I'm retired & have the time to dead head, nearly daily (whew) even thru this past wks of ~heat~wave~ they look better w/o the wilted spent blooms!
FWIW!

I would be very suspect about the hardiness of any hebe in zone 6 but more specifically, the two mentioned. These are speciosa hybrids and IME, speciosa is one of the least hardy of any hebe species. You could winter them over in a sunroom or greenhouse but as an evergreen shrub, they will need light regardless of temperature.
FWIW, Strawberries and Cream is assigned a zone 9 rating by at least one North American supplier. Based on my experience with these types of hybrids in my rather mild, maritime zone 8b climate, I'd say that was a very reasonable rating.



Again... i would just keep an eye on it for the standard signs just in case. Has it bloomed out any normal flowers yet?
Talking with a few nurseries here that have big aster yellows infected coneflowers, have noted that plugs coming from their growers must be infected when they receive them. It seems to be a horrible issue this year.




aha, the Chelsea Chop - yep, I do this with asters and helenium as well as phlox - works a treat.
I do not pinch back my phlox because the deer do a thorough job of it. This year one area his been eaten at least twice and are very short but they are still setting blooms.
