Vanda

Vanda is a genus of mostly epiphytic orchids, sometimes terrestrial.

They are found in tropical forests from the southern Himalayas, in India, to northern Australia where they grow up trees where the bare roots absorb rainwater and dew.

They are mainly grown for their flowers and sold as cut flower or plant in a glass vase, without substrate. While it’s beautiful, it is not the best way to grow them.
