To All, I grow Gladiolus huttoni, formerly Homoglossum. It escaped and formed a small patch on my hillside 10 years ago. Regular frosty winters haven't phased them. This winter we had an "Arctic Express" and the temp. went to 15 F. for a number of nights. I attempted to protect all other plants, but forgot Gl. huttoni. Now they are displaying their gorgeous scarlet blossoms. Bob Werra in inland no. Calif.
