Dendrobium discolor

Antler orchid

A large, sun-loving 'antler' orchid of the coasts of tropical Queensland, New Guinea, the Moluccas and Sulawesi. It grows on trees, mangroves and exposed rocks, often close to the sea. Its canes can reach several metres, and it produces long sprays of twisted, wavy, golden-brown flowers. Grow it hot, bright and airy, with a drier rest after the canes mature.

Where it grows wild

Epiphytic or lithophytic in coastal scrub, on mangroves, in coastal rainforest and woodland, and on exposed rocks, often right by the sea. The cane-like pseudobulbs can reach up to 5 m, and each carries 10–35 leathery leaves.

Recorded at 1–760 m, with a median of 30 m, so it is essentially a coastal lowland plant. The measured sites are at 2–250 m.
