The orchid group includes several several hundred different genera and thousands of species, but most people are introduced to orchids through the Phalaenopsis genus, which are particularly good orchids for beginners. These are thick-leaved plants with elegant, arching sprays of bloom—the orchids featured in so many design magazines sitting on coffee tables across America.Phalaenopsis orchids are rewarding plants. They are not demanding, and in the right conditions, they will display showy blooms for months.How to Grow Phalaenopsis OrchidsPhalaenopsis orchids are hardy in zones 10 to 12, where they can be grown outdoors in warm, humid conditions that are damp but not soggy, in a location that is shady but bright (no direct sun). More often, these plants are grown as indoor potted plants, where successful growth means finding the right balance between humidity, temperature, light, and airflow. Their long-lasting flowers are held on arching branches and open successively. A single multi-branching flower spike can have more than 20 flowers, and individual flowers can last for weeks.
