Description Calla lilly is an easy to grow perennial known for its beautiful, funnel like summer bloom.

  Morphology:
Calla lilies are in the arum family (best known for jack-in-the-pulpit). Calla lilies are not true lilies as such but rather originate from rhizomes, as with Dutch iris. Flowers consist of a yellow finger-like spadix surrounded by a bright white spathe borne atop a leafless stalk. Depending upon the cultivar planted bloom can be white, pink, red, pale yellow, or blue.

  Adaptation:
Best raised in moist soils with full sun to part shade. They can be successfully overwintered outdoors in colder regions (zones 6-8) if properly mulched. The Zantedeschia species are very poisonous, capable of killing livestock and children. Handling plant may cause skin irritation or allergic reaction.

  Pests:
None reported in the Northwest.
