Why Calla Lily Flowers Turn Green: Understanding the Natural Life Cycle

The Green Spathe: A Normal Stage

If your Zantedeschia (calla lily) blooms have turned from white or purple to green, don't panic. This is a natural part of the plant's reproductive cycle.

What's Happening?

The showy "flower" is actually a modified leaf called a spathe. After pollination, the spathe turns green and encloses the developing berries (the compacted green structure you noticed). As the berries ripen, the spathe eventually rots away, revealing succulent yellow berries that attract birds for seed dispersal.

What to Do

• No intervention needed—this is normal.
• If you want to prevent self-seeding, remove the spent spathe before berries mature.
• Continue regular care: keep soil moist but well-drained, provide partial shade in hot climates.

Enjoy the unique transformation; it's a sign your plant is thriving and completing its life cycle.
