If anyone wants yellow crocosmia's , just ask. I've got hundreds of them and am more than willing to share !
I don't know which cultivar they are since I got them from an abandoned property years ago.
This particular variety is pretty tenacious and multiplies like crazy. I don't know how they'd perform in colder zones, but here, mine literally sit in standing water for months at a time in winter and they still bloom. They're in full bloom right now and get about 36-40" tall.
