Justafewdahlias could the curling in be heat or other stress or are all the flowers on that plant doing it?
SO funny you post this because I posted on my FB and IG the other day wondering if the frilly white cosmos flowers here are a new form. I have been saving and growing my own seed for a few years now but always also buy apricotta cosmos. The frilly white ones look like the shape of apricotta but I don't recall seeing that in a white cosmos and wondered if I should try selecting for it. Does anyone here know?
