Dendrobium speciosum, or rock lily, is a popular and easy to grow Australain native orchid. It bears showy racemes of cream flowers sometimes 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 and can also be attached to logs.
