The listing, very rare...petunia exserta...cannot buy these has ended.
Up for bid are 20 small seeds from the petunia exserta plant pictured. It has sprung back to life since our hot Texas weather has ebbed but the humming birds have gone south already so I'm not certain I will get any pollination this late in the season. I received the seeds of this. Specimen from a collector in California and grew it out early. This is reported to be one of the only wild petunias loved by Hummers. More info on where this plant was discovered can be found at this link.
