Rosie - the species is Plieone formosana.

I'll tell you an interesting thing I learned about them through a little narrative:

Someone sent me a corm to experiment with, so I potted it up in S/H culture. It bloomed nicely, then the foliage came up and it grew well. As Autumn approached and it started to die back, I realized I'd need to give it a winter rest (I just don't do that for my plants), so - being a converted deli container - I snapped a lid on the pot, so it wouldn't get fed and watered, and put it in a cool, shady place. AND FORGOT ABOUT IT UNTIL THE FOLLOWING MAY...

When I remembered it and opened it up, the space between the LECA and the lid was a mashed mass of foliage!

It continued growing nicely for several more years, but the submerged corms all grew on top of the medium, forming an irregular, ugly mass. It then went back into a "semi-terrestrial" mix and was later given away.

Oh, my, what lovely flowers and photos. Great growing, RosieC ! I would be more than pleased. I'd be doing the happy dance. LOL

Thanks Picotee and Ray,

I had thought the name was formosana then saw it as formosa somewhere and thought I had got it wrong. Hmm... I've checked the tag and that's formosana (written by the seller). No idea now where I got the formosa name from. I'll change the thread title, thanks for the correction :)

I take these out the medium each autum and repot each spring, otherwise they would get higher in the medium as the new ones always form higher on the surface, even with standard medium.

Very Nice,Rosie
they are so delicate looking
Photo is great too :)
