Phalaenopsis
Phalaenopsis spp. and hybrids
📖 About this plant
The most popular and widely grown orchid in the world, commonly known as the ‘moth orchid’ for its broad, flat, rounded flowers that resemble moths in flight. Arching sprays of long-lasting blooms (often 2-4 months) come in white, pink, purple, yellow, orange, and patterned varieties. Compact, easy to grow, and adaptable to typical indoor conditions, they are the ideal first orchid. With proper care, they can re-bloom on the same or new spikes for decades.
🧑🌾 Care requirements
Bright indirect (4-6 hrs)

High (50-70%)

Medium-grade orchid bark or specialized Phalaenopsis mix (bark, sphagnum moss, perlite); some growers use sphagnum moss alone; avoid standard potting soil — roots need air circulation
Weak balanced orchid fertilizer (quarter to half strength) every 2 weeks during active growth; 'weakly, weekly' approach; reduce or stop in winter; high-phosphorus bloom booster when flower spikes initiate
