Cannas
   

 

     

With bold flowers and bolder foliage, cannas are the flamboyant clowns of the perennial world. Extremely popular in the Midwest, South and East, their use in California landscapes has been limited for a number of reasons.

Cannas like warm nights. Although our climate is warmer year round, Eastern nights in May or June are warmer and more humid. Our cold spring nights slow the emergence of cannas from their semi-dormant winter state. For best results, protect cannas from cool coastal breezes and plant them where pavement or masonry walls will re-radiate heat at night.

Cannas can go dormant or look straggly. The key to canna vigor and appearance in our climate is a simple grooming technique. After the first cluster of blooms on a cane has finished, cut that cane back to the ground. With secondary bloom bud showing, it is tempting to remove just the spent blooms. If this is done, over time the plant habit will become more and more sprawling, with spindly new canes.

Canna viruses. A complex of at least four viruses together cause slow spring growth, reduced vigor, streaky foliage and misshapen blooms. Our mild winters allow cannas to avoid full dormancy, which allows the viruses to over winter. The viruses are spread by cutting tools and insects, so most cannas in California are infected. Virus free plants are usually infected within a year. Some of the varieties that suffer worst from virus symptoms include: ‘Lucifer’, ‘Technicolor’ (Pink Sunburst), ‘Wisley Dwarf’, ‘Panache’ and ‘Ehemanni’. The key is to plant vigorous virus-resistant cultivars, site and prune them properly.

From over 300 varieties tested, we have found the following varieties to be best for year round performance in California. They may show some virus symptoms in spring, but will grow out of the symptoms, usually blooming through November. Cannas are available only in 5 gal. containers. Pick up at nursery only.
