I remember Mose in this forum mentioned Dee-lish blooms became crispy in hot summer. So I planted mine in a place with afternoon shade. It's still young, so I will see how it does in thethis summer.

Mine do crisp, as KJ stated above, but not the worst crisper. My Poseidon is a crumpledcrumpledcrumpledcrumpled & faded taupe colored glob the first day it is open, needing dead heading, ASAP. it's my worstworst.

I have intense, fulfull sun here in the 'Burgh...not typical of gardens around these parts. The microclimate phenomenon hits my garden hard. I have summer growing conditions much likelike one would have in the desert.

Thanks @Moses, Pittsburgh, W. PA., zone 5/6, USA ! I will try to find a spot that gets afternoon shade for my Deelish.
