❓ Frequently Asked Questions — Comparing These Plants

Calliandra

What are the light requirements for Calliandra?

Calliandra plants need bright, indirect sunlight to thrive. Direct sunlight can scorch their leaves, while insufficient light can lead to leggy growth and reduced flowering. Ideally, place your Calliandra near an east- or west-facing window where it can receive several hours of bright, indirect light each day. If you’re growing Calliandra indoors, consider supplementing natural light with a grow light, especially during winter months or in dimly lit spaces.
