New Cannas!

I've been experimenting with growing some Cannas from seed. They are just poking their heads up above the potting mix now! Should be ready to plant outside on about June 1. I'll post some pictures as they grow!

Cannas don't come true to their parent when you grow them from seed, but it is interesting to see what you will get. New colors, leaf forms, and other surprises await when you go this route.

Canna seeds have a very hard outer shell on them. In fact, some think that in centurys past, people used to use them as shot for hunting. One species, Canna indica, even bears the common name Indian Shot because of this. In order to get them to grow, you must scarify them first. Basically, this means that you need to file or cut a notch in the outer coating. Use a triangular file and cut down until you see the white endosperm material. Soak the seeds for a couple of days in water (changing the water daily helps too). Then plant them in a soilless potting mix at a depth of about 1/2 inch. Keep them at a temperature of 70-75 degrees. It takes about a week or so for them to germinate. Fertilize with Miracle Gro as you water. Keep the potting mix moist. When they finally do pop their heads up above the growth medium, put them in a warm, sunny spot and enjoy!

After all danger of frost is gone, they should be planted outside - either in a container or in a well-prepared garden spot. They will blossom all summer long if you keep them watered and fed.
