Can anyone identify this plant?

I photoed this in a public park in Causeway Bay, HK.
Can anyone help me identify it?

I've seen it in Rockledge Gardens nursery in Florida, I think they call it an African iris.

Thanks, Mittsy, I'll check that out.

Jim, I had what I think you saw just bloom for us that was a gift from another DG gardener a few years back. It was the first time it ever bloomed. Pretty thing. . We keep it in the GH in the winter. It grows new plants like a spider plant does. Patti

Patti, that's it! If you ever have a spare plantlet, I'd love to swap it for something you want.
I have LOTS of heirloom tomato and pepper seeds.
Maybe I have other things that would interest you.
Best, Jim

Jim, I should have one to spare at some point, I will dmail you for an address. Love Rhinebeck and all the area around Hudson. Hope you post about your heirlooms in the northeast forum on the veggie thread. Patti

I have the yellow variety in my patio garden in Cocoa Beach.

Wow! There's a yellow one, too?
Can we do a deal some time, mittsy?
Patti: I just posted in the NE veggie thread!

Pretty....boo hoo tho, it looks like it's only hardy to zone 8......

Sure.
