Ornithidium densum

Conservatory Greenhouse Houseplants

An epiphytic, evergreen orchid producing a clump of small, oval-shaped, flattened pseudobulbs, growing from a long, horizontal or pendulous rhizome, covered with thin, dry bracts. Each pseudobulbs carries one, up to 30cm long and 3-4cm wide, leathery, narrowly-oval leaf. In winter and spring, clusters of short flowering stems emerge from the axils of dry sheats, carrying small, scented, pinkish-white flowers, 1-2cm in diameter

How to Grow

Cultivation

Grow in an open, free-draining, medium-grade, bark-based orchid mix with addition of perlite, sphagnum moss or coir. Requires day temperatures around 18-20°C and 14-16°C at night. Provide good light levels, but avoid direct sunlight. Water plants thoroughly when compost is almost dry, allow to drain and use orchid fertiliser regularly during growing season. See also indoor orchid cultivation

Propagation

Propagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided in early or mid spring, when the plant overgrows its container. Each division should have at least 3-4 healthy, older pseudobulbs with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting
