Product Overview
SEED TREATMENT: scarification
ZONE HARDINESS: 7(possibly only 8)-12 especially if mulched during winter. If growing in colder zones, the tubers can simply be harvested in fall and stored somewhere protected from the cold, and then replanted in spring.
-I successfully overwintered them in an unheated hoophouse in zone 7a. -Who knows, perhaps some of the seedlings will prove to be exceptionally hardy.
-The main photo of one of the cultivars that seed is harvested from after one growing season in zone 7a.
-Canna edulis has a huge potential as a starch crop. It has large starch particles that can easily be extracted to make a flour.
