Brent:
The common form of Gladiolus papilio is not the most attractive species
glad, but must be one of the most hardy. A corm from our clone
hitchhiked on a plant that I shared with a friend in Minnesota. The
glad has rapidly spread and survived below -20F with no problems and no
protection. This certainly should be a good breeding candidate.
