About

Dendrobium secundum, the toothbrush orchid, is a large, compact epiphytic orchid with dense, upright canes to 60 cm long. All flowers along the densely packed, arching to erect, one-sided raceme face the same direction � a striking structural feature. The small, 1 cm, pinkish-purple flowers with an orange lip are freely produced over the whole length of each raceme. A distinctive and ornamental orchid for a warm to hot greenhouse.

About the genus

They produce elongated, cane-like or club-shaped pseudobulbs bearing linear to ovate leaves, and racemes of showy flowers from nodes along the stems, mainly in spring and summer. Dendrobium span a huge range of sizes, habits and cultural requirements.
