It's a Celosia, spicata group, maybe 'Flamingo Feathers' Here is a link that might be useful:

Hi Liz! Yep, that's my hand! Nice to see you here too. Hope you're doing well. I harvested some heucheras a few years ago, and I have to warn you they were a bit of a pain. The seeds were tiny little specks of dust that had to be pried out of tiny seed pods that formed on the stalks where the little flowers had been. I haven't bothered harvesting them since then, and I often get little baby heucheras self-sown all over the bed where I have them. Rather than harvesting the seeds, I now basically harvest the self-sown babies. If they aren't growing somewhere I like, I just move them. They're all babies of Palace Purple, I think, but I don't mind. I tried sowing some seeds bought from Gardens North this past winter, but I didn't get anything that differed markedly from my own Palace Purple babies, so I don't think I'll bother gathering my own seed or sowing them again.

Thanks kaliaman. Must be migrating north, you know - global warming! I see it is ordinarily native to Florida. My neighbor here in Cary NC has had it growing "wild" for years and I hope mine will reseed next year. It's a great plant. Produces constant blooms.

I bought dendrobium from my local store in my country (cambodia). I've trying to grow those but turn out the flower like the one in picture. So what can i do?
