Plant description

dendrobium speciosum rock orchid

Dendrobium speciosum, or rock lily, is a popular and easy to grow Australain native orchid. It bears showy racemes of cream flowers with purple spotted throats in spring. It naturally grows as a lithophyte, growing on rocks, or sometimes as an epiphyte, growing on the trunk or branches of trees. It is not well adapted to growing well in normal soil, so should be grown in a position that is similar to the natural conditions. It can be grown in a pot with a good orchid mix. They can also be attached to logs or branches, or in rock crevices or shelves, with a good amount of leaf litter, bark chips or orchid mix placed around the roots. It likes a spot in dappled shade. It is not frost tolerant.

Propagation is by division of the clump. A spade or sharp instrument may be neeeded to separate the clump, as the plant is tough.

Dendrobium speciosum has been renamed Thelychiton speciosus.
