They never made it much taller than six inches. Two survived and to my knowledge neither of them flowered. I'm pretty disappointed about it either way. I planted them behind some golden Spireas so I was looking forward to the contrast. The flowers are supposed to be pretty nice and I certainly wouldn't mind having some cotton.
(I have no idea if this is a bud or seed..or hat...or..)
Honestly, I have no idea how cold hardy these are supposed to be. No one has really posted too much information on them. I would love it if they happened to be perennial, but based on standard cotton varieties, I'm not going to hold my breath. I mulched the hell out of them just in case. Who knows, with all the green trees here in New York, I don't even know if we're really having winter anymore.
I think I'll try them again next year if I have somewhere to keep it in a pot. I imagine the differences in soil and just the general neglect of things at my fathers house might have been difficult for it. Maybe it will do better if someone paid more attention to it. It does seem to be an attractive plant once it gets going.
