A reference to orchid genera that prefer cooler conditions and benefit from protection from frost.
Most Cattleyas are epiphytes from tropical America. Their pseudobulbs carry one or two leathery leaves, with large showy flowers.
Use a free-draining bark or coconut-husk mix. Give bright filtered light, good air movement and regular water while actively growing.
Cymbidiums are strong growers valued for their long flowering sprays.
Grow in a large, free-draining container. They appreciate cool nights, bright light and regular watering and feeding while growing.
Oncidiums include many epiphytic orchids with branching sprays of flowers.
Use an open mix, provide bright filtered light, good humidity and steady water while the plant is active.
Zygopetalums are clumping epiphytes or terrestrials from Brazil with prominent pseudobulbs and patterned flowers.
Grow in coarse bark or coconut-husk chips with high humidity and air movement. Shade in summer, provide brighter winter light and avoid wet leaves in winter.
