Difference Between Calla Lily and Arum Lily - Comparison Summary

What are Calla Lillies

Calla lilies are beautiful plants with trumpet-shaped flowers that come in many colors. You can find them in classic white, yellow, orange, pink, rose, lavender, and dark maroon. Their leaves are smooth and shaped like swords, often with white spots.

These plants grow well in warm places with full sun or some shade. In cooler areas, they need full sun to grow their best. Calla lilies can survive winters in zones 8-10, but in colder places, you’ll need to dig up the bulbs in fall and store them indoors to replant in spring. It’s best to plant them after the frost is gone and when the soil is warm, at least 65°F.
