Zantedeschia

Zantedeschia, or calla lilies, are comprised of 6 species of rhizome-rooted plants from southern Africa, as well as numerous hybrids.

Callas are made up of a “flower” or bract (in a number of colors) which surrounds a central spike or spadex. The foliage is green and sometimes very glossy, arrow shaped or lanceolate and often spotted.

Calla lilies are beautiful in wedding bouquets and fresh floral arrangements. The perennial types make a lovely addition to the woodland or cottage garden, while annual varieties add a lot of color and structure to summer containers and warm season borders. Perennial varieties of calla lilies bloom throughout spring while the annual varieties bloom throughout the summer.

Flower colors for perennial callas commonly found at Portland Nursery include bright whites and dark purple/blacks. Annual varieties sold at the nursery have flower colors ranging from red, yellow, orange, pink and purple. Good companion plants for perennial calla lilies planted in the woodland garden include ferns, astilbes, hostas, ligularias and impatiens. In a container, annual calla lilies combine well with petunias, dusty miller, allysum, creeping jenny, heliotrope or dichondra.
