Vanda Orchids – Orchid Facts

Vanda Orchids

Some of the 40 existing Vanda species are epiphytic in their countries of origin. The strap-shaped, leathery leaves are set on in regular double rows or sometimes arranged like roof tiles on a long stem. The flowers appear in upright inflorescences that grow sideways out of the leaf axils. Vandas rarely grow taller than 120 cm (48 in) in a greenhouse, conservatory or flower window. The most beautiful species is the strictly protected Vanda coerulea. Its flowers are an incomparable shade of blue that otherwise never occurs in orchids or any other flower. Multicoloured Vanda tricolor spreads a strong scent.

As well as the large-flowering Vanda hybrids, other species are also for sale in specialist orchid nurseries. Crosses with Ascocentrum are recommended for use on windowsills as they remain small.
