to MID

Common Name White Bottle-Brush Orchid [Australia] - Small-Headed Flower Dendrobium

Flower Size 1/2" [1.2 to 1.8 cm]

Found in Papua New Guinea and the Solomon Islands as a small sized, cool to hot growing epiphyte on trunks and branches of trees in lowland savannahs, plantations, coastal forests and rainforests but it is also a lithophyte and is found on rocky outcroppings in grasslands at elevations of sealevel to 1800 meters with spindle to cylindrical-shaped, several noded, constricted basally pseudobulbs carrying many, apical dark to gray green on the upper side and velvety purple on the underside, thin, leathery, narrowly lanceolate to elliptical, unequally bilobed apically leaves that blooms with a ball-like cluster of many flowers that arise from the nodes closer to the middle and base of mature leafy and leafless canes arising on dense ovoid clusters of suberect, 3/4" to 1 1/2" [2 to 4 cm] long inflorescence occuring in winter through mid spring.

This plant can be mounted or grown in a pot with a fast draining medium and can be grown with much more even conditions than many Dendrobium. A lessening of fertilizer can be benificial to better spring blooming but watering can basically remain the same.
