These are the corms from two seasons of growth from seeds. The seed parent was a relatively cold-hardy Gladiolus named 'Boone' that I think was recovered from an old homestead in North Carolina (?). It has grown here since 2009 unprotected but against a wall. The pollen parent of the seeds that grew these corms was the tender, winter-blooming, night-fragrant species, Gladiolus tristis. I had to freeze its pollen for several months to be able to use it on summer-flowering 'Boone'. I sure hope at least a few of these will bloom this coming summer.
