I'm looking for seeds or corms of canna stuttgard and musifolia
You should go to Humber Nurseries and pick up one of their Canna Stuttgarts. I did a few weeks back. They had a few really gorgeous specimens in 3 gal pots for $34.99. They were about 7' tall with about 6- 8 stalks. I've spent the last few years trying the packages of stuttgart rhizomes. I found many of them were not even stuttgart.

If you want, you can have mine once the season is over. At the moment it's growing in a mixed container so I don't want to rip it out until fall.
