Why Calla Lily Flowers Turn Green

Why Calla Lily Flowers Turn Green

A reader’s two yellow potted Calla lilies (Zantedeschia) in a gazebo have turned from yellow to green.

Natural Dormancy Cycle

This is normal. Calla lilies bloom for 4–6 weeks, then the flowers green and brown as the plant enters dormancy. The tubers need a rest period to rejuvenate.

Care During Dormancy

• Stop watering; let the soil dry out completely.
• Store pots in a cool, dark place (or leave in ground in zones 7–10).
• After 2–3 months, resume watering and light to trigger new growth and blooms.
