Dendrobium parishii is a deciduous orchid native to lower elevations in Southeast Asia. The thickened stems are usually prostrate or pendulous, to ½ inch (1.3 cm) thick by 12 inches (30 cm) long. They are easy to culture and a good orchid for beginners.
Blooming: In late spring to early summer, the 2 inch (5 cm) wide rose to lilac purple flowers appear on leafless stems.
Culture: Dendrobium parishii need full sun to partial shade with fast draining compost. In the greenhouse, we use a compost consisting of Osmunda fiber and long fibred sphagnum moss with small bark chips added to help with drainage. During the growing season, water freely and fertilize every other week with a high nitrogen fertilizer or an orchid special fertilizer. In the fall, temperatures should be dropped to around 55° F (13°C) for the winter rest period. Water should be restricted at this time and no fertilizer is needed. Plants should be given full sun during this period to help improve flower initiation.
Propagation: Dendrobium parishii are propagated by division after flowering.
