Valerie, Ive had fun with these new varieties for years now
they need to be treated differently to normal echinaceas. They mostly have a tendency to wilt as soon as flowers are forming and/ or fail to survive winter. I remove all flower stems ....just done this with Tiki Torch and Vintage Wine.....and encourage the root system to grow instead. if a young plant dont let flowers form until the following summer. If established let flowers form in late June then they will perform well.
there are exceptions...most of the doubles like Marmalade, Hot Papya, Double Decker, Milkshake seem to be more robust.
summer Sky is a durable robust variety. it has survived several winters here now and about to start flowering ....flower stems removed a few weeks ago.. Also the seed raised Cheyenne varieties have over wintered well and reputedly very robust. salsa too has built up good clumps and again ready to flower
the normal well know varieties are a different kettle of fish to the above varieties.
I find they need an occasional good watering and mulch. a seaweed spray or two in summer helps. good soil produces better plants
