Wilfred and Suzanne at Mount Spec Road have a beautiful spider orchid in full bloom at present (Dendrobium tetragonum var. giganteum). The orchid is growing on the bark of a large tree and it is a rather small and inconspicuous plant – that is, until it is in flower. It currently has multiple delicate blooms which are spider-like in shape.
Spider orchids have distinctive four-angled stems. They generally grow in mountain rainforests, on tree trunks and often near watercourses. The flowers can be up to 10 cm long with attractive markings. The flowers are greenish to yellow in colour with prominent red to purple blotches. Spider orchids flower intermittently from April to November.
