Canna
brasiliensis
This is probably the
hardiest of the species cannas, growing to about 3' with narrow
plain green leaves it will self-seed around the garden. The
flowers are small red and yellow and are followed by the inflated
seedpods. It can stay in the ground all winter and will be ok down to -10c (provided the
ground does not freeze) when it will die down and flower from
July on. If it has some protection however, and in milder
gardens, it will remain evergreen (min 0c), and be in flower from
March to December. The main snag is the damage that can be caused
by slugs and snails.
