|I am getting conflicting info about cannas. Is it OK to plant them in the garden for the winter or do I need to keep them inside and split them in the spring to create more plants?

|Your zip code places you in USDA gardening zone 7. In zones 7-10 cannas can be safely left in the ground during the winter. Zone 6 is a median climate for cannas. Cannas grown in zone 6 can be left in the ground during less severe winter seasons but always have the possibility of freezing during more severe winters. Cannas grown in zones 5 and colder must be dug and stored during the winter. Hope this clarifies things for you.
