RE: digging canna bulbs

> Can any types of Cannas be left in the ground in zone 7?

Yes, and it might help if you mulch them well.

Reasoning:  I've left cannas in the ground for the last two winters.
They've survived, revived and bloomed again in that same brassy pink shade
that bothered me so much the first year I planted them.  I think they
appreciate well drained soil during the cooler season...to avoid root rot in
their outdoor storage location.

Now, if you happen to *like* your canna's colors, all Zone 7 survival bets
are off...
