About
A medium-sized, tropical, evergreen, epiphytic orchid hybrid producing a clump of elongated, upright, cane-like stems. Each cylindrical, sometimes spindle-shaped stem (pseudobulb) is up to 15cm long, carrying 1-3 firm, vivid green leaves. The leaves are lance-shaped, leathery and partially glossy, measuring up to 20cm long and 3cm wide. Two to seven large, star-shaped flowers are carried on flowering stems emerging from the tips of young, mature pseudobulbs. 'Hihimanu' is cultivar with very pale, almost white flowers, occasionally with a hint of pale pink on the tips of sepals. This is a complex orchid hybrid with 5 different genera and altogether 12 species in its ancestry.

Care notes
CultivationGrow in an open, coarse bark-based orchid mix with addition of perlite and coconut chips. Provide bright light conditions, but shade from hot, direct mid-day sun. Ideal temperatures are 15°C minimum in winter and up to maximum 28 °C during summer day. Water and feed plants regularly during the growing season. Ensure that all water drains away, preventing the plant sitting too wet. Provide enough humidity by regular misting. Reduce watering and feeding in winter months and keep in a bright, sunny position. As with many orchids, they grow best when well-established and slightly pot-bound. Re-potting should be only done if the plant overgrows its container or before the potting mix starts to deteriorate - approximately once in 2-3 years. The plant should only be re-potted when the new growth appears in spring. See also indoor orchid cultivation.
PruningNo pruning required.
PropagationMature plants may be divided when the plant overgrows its container. Each division should have at least 3 older growths with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting.
Pest resistanceMay be susceptible to glasshouse red spider mite, scale insects and mealybugs. Thrips may cause damage on flowers.
Disease resistanceGenerally disease-free. Poor air movement may cause bacterial or fungal rots. Good hygiene practice and sterilising cutting tools prevent the spread of virus diseases.
