It depends on what Canna you have. Most of the popular hybrids have non-viable seed. Species canna starts easily from seed although scarification is needed. Al

I was unaware of that. Good to know. The canna in Q was a generic BBS plant. I will likely plant the seeds next spring since I have them, but without any expectations.

Thanks.

Cannas will often flower in their first season from seed if started early enough.

I have successfully grown plants raised from seed collected from named hybrids.
