|My red cannas have formed pods and large brown seeds. I would like to try planting them next spring. As I live in zone 5, I'll be growing them in the basement under grow lights. When would be an appropriate time to start them? I'm assuming they will take quite a while to grow large enough to bloom. They seem very hard. Do you think it would work?|
|I would suggest you start them now to get plants ready for next spring planting.|
Chip the seed coat to break it so moisture can readily enter the seed. This may be done several ways. Many gardeners use a file, pruning snips or sandpaper to break the coat. Next soak seeds for 48 hours in warm water, changing the water after 24 hours. Then plant 1/4 inch deep in a peaty mix and keep warm and moist until they germinate (which may take a month or more).
Have fun with your canna project!
