Common Name Johan's Dendrobium [John Gould Veitch, 1st orchid breeder] - In Australia The Chocolate Tea Tree Orchid

Flower Size 1 1/2" [3.75 cm]

This small to large sized, hot to warm growing epiphytic species that comes from northeastern Australia and Papua and New Guinea in and around rainforests and swamps with scarce winter rain and high light has densely clustered, brown, unevenly swollen pseudobulbs carrying 3 to 8, on the apical one quarter, lanceolate, dark green, tough, thick leaves that are sharply pointed apically. The bloom season is mainly from spring through fall and winter occuring on a 6 to 20" [15 to 50 cm] long, axillary, several to many [2 to 20] flowered, racemose inflorescence with waxy, glossy, fragrant [not so nice], longlasting flowers that arise from the nodes at the apex of leafy and leafless canes.

If the plant is properly dried out through the winter months and given no fertilizer until spring when the new growth is visible blooming and a healthy plant will follow.
