This is a group of about 50 species of sturdy single-stemmed orchids with representatives from Sri Lanka and India, across Southeast Asia to New Guinea and northeastern Australia. They are erect growing, with straplike semi-rigid leaves in 2 ranks. Larger plants may branch at the base, and have numerous, very thick, cordlike roots. The flowers appear from the stem at the base of the leaf. They have showy long-lasting blooms, which come in a range of colors, often with delicate markings. This is one of the most important genera of plants for cut-flower production in Thailand and Singapore. A large export industry has developed using a handful of species in an extensive hybridizing program, both within Vanda and in combination with related genera.
CULTIVATION
Vanda plants are easy to grow in wooden baskets, with most thriving in bright, humid, and warm to intermediate conditions. During the warmer months they require liberal watering; reduce this over winter. Plants are mostly frost tender.
Top Tip
Vanda plants need a coarse growing medium, so add charcoal or bark chips to the potting mix. Humidity is also important-regularly spray the leaves with a fine mist of water.
