will canna grow if you leave them outdoors in the ground over winter

Question

I left my canna in the ground over the winter. I want to know if they will grow again and, if so, what month do they usually grow?

Answer 1

No, canna lilies are tropicals, and the cold of a Philadelphia winter would kill them. They're easy to overwinter, though. Read more in these two articles: https://www.gardeningknowhow.com/ornamental/bulbs/canna/canna-lily-care.htm
