Common Name Hellwig's Dendrobium {German Botanist in New Guinea late 1800's]

Flower Size 3/4" to 1 1/3" [2.5 t o 3 cm]

Found commonly in Papua & New Guinea in mist forests at elevations of 1400 to 2700 meters and is a small sized, cool to cold growing epiphyte that likes cool, damp shady conditions. This orchid has a tufted, sometimes branching stem carrying 1to 5 apical, fleshy, nearly terete [chive-like] leaves bloomin on a very short, axillary, 1 to 3 flowered inflorescence that arises from the nodes at or near the apex of older leafless and leafed canes with the very long-lasting flowers held nestled in the leaves occuring most often in the fall but is possible at any time. Keep this plant dryer between waterings in the winter months and also reduce the fertilizer.
