Susan, the species glads aren't hybrids, wildflowers that occur mostly in Africa. The modern hybrid glads hardly even resemble the naturally occurring species any more. There is a graceful, airy quality about them that has been lost in the stiff, modern hybrids we're used to seeing.
Barb, how cold does it get in winter there? I wonder if some areas of the deep south would suite winter blooming species? I'm going to send these that I started from seed to 4paws, who is living in Florida now- I think she'll have a good chance of seeing them do their thing in the garden.
