Dendrobium vexillarius orange outcross #4346 ('6521' x'3316') (approximately 25 seedlings per flask). This species needs specialized conditions and can be difficult to get out of flask. It is not recommended for beginners.

The Species: It grows at elevations ranging from 3650 to 13,200 ft in New Guinea, New Ireland Island and the Moluccas. It is most often found at elevations between 6550 to 11,150 ft. It grows as an epiphyte and occassionally a terrestrial in moss in bright light with cool temperatures. At the lower elevations of its range it grows at the tips of horizontal tree branches. At the higher elevations it will grow on the surface of the ground in a deep layer of peat, humus, and moss.

Culture: I grow this species with 50F nights, even moisture, regular fertilizer in moderately bright light. Like most plants from New Guinea, good water quality is essential. I use 1/4 strength fertilizer at almost every watering (lower in the winter) because I have RO water, but it may do better with a bit more dilute fertilizer if your water has minerals in it. I do best with this species mounted on wood or cork (with high humidity) or potted in sphagnum moss in a terra cotta pot, but many people also grow it successfully in a fine bark mix. If you can't keep the night temperatures down, it does not thrive.
