A pendulous, fragrant dendrobium

This is Dendrobium anosmum, a large epiphytic orchid grown for its long, cane-like hanging stems and its spring flush of pale pink blooms. Despite the species name, which suggests no scent, it is in fact a fragrant orchid within the vast Dendrobium genus.

Native to South and Southeast Asia

Its natural range stretches from Sri Lanka and Bangladesh across to New Guinea, taking in Myanmar, Thailand, Vietnam, Laos, Malaya, the Philippines, and much of the Indonesian archipelago. In the wild it lives as a pseudobulbous epiphyte or lithophyte, rooted on trees or rocks within the wet tropical belt.

Warmth, light and a dry winter rest

Give this orchid bright, filtered light year-round and warm days of roughly 25-30°C with cooler nights of 16-20°C, since that day-to-night swing helps drive flowering. Water and feed generously through the growing season, but from October cut both back and let the plant rest through winter until warmth returns and triggers new growth. It prefers a bark-based, well-drained epiphytic mix and, like most orchids, resents having its roots disturbed or overpotted.

Division or keiki cuttings

Mature plants can be divided once they have outgrown their pot. Sideshoots, known as keikis, sometimes form on older canes; once these have roots at least 2cm long they can be removed and potted into sphagnum moss. Raising this orchid from seed is only realistic in a controlled laboratory setting, not at home.

Cane stems, one flower per node

Stems reach around 120cm, jointed and pendulous, each new one wrapped in leaf-sheaths bearing a single glossy, deciduous leaf. Short flower stalks emerge from the nodes of mature, leafless canes in spring, each carrying one large bloom around 7cm across, usually pale pink but ranging from whitish to dark pink. The lip is densely hairy, which is the most telling feature of the species.

Watch for common orchid pests

This species can attract scale insects, aphids, mealybugs, and red spider mite, so it is worth checking new growth and leaf undersides regularly. Otherwise it is generally free of disease.

Light-touch pruning

No routine pruning is needed. Spent flowers can be removed as they fade, but leave the cane itself alone unless it has fully shrivelled after some years of growth. Older canes may eventually be cut away, provided enough younger ones remain to support the plant.
