Alternanthera (Calico Plant) Not Suited for Indoors

Alternanthera hybrids (calico plant, parrot-leaf) are outdoor tropical border plants. They need:

• Full direct sun (more than a sunny window provides)
• Warm temperatures
• Consistently moist soil
• Regular fertilizing

Indoors, they become leggy, lose color, and decline. Use them outdoors in zones 10+ or as annuals.
