Dendrobium is one of the largest genera of orchids. Many of them are lithophytic and epiphytic, so they can be grown on rocks or on trees, including the Dendrobium speciosum, which is an Australian, sometimes called the King’s Orchid or the Rock Orchid. It was first named in 1804 from a specimen collected by the surgeon of the first fleet, John White. It forms large clusters, with thick “pseudobulbs” and leather leaves. The plant blooms in late winter and early spring, with spectacular tassels, grouped with small scented flowers in color from white to cream yellow or gold. To see them in the bushes in early spring, this is a wonderful sight.
