pinecone-like raceme dendrobium

An epiphytic, medium-sized orchid with long, cane-like stems (pseudobulbs). Five to seven dark green, lance-shaped, leathery leaves are alternately arranged on the upper half or near the top of each pseudobulb. Each leaf is up to 15cm long and 3-4cm wide. Pendant flowering stems emerge from the axils of leaves on mature canes and bear up to 30, densely arranged flowers. Each flower is 3- 5cm large, white with dark yellow lip. The lip is round, with frilled edge. Petals and sepals are usually white, sometimes pale pink.

Grow in an epiphytic, medium grade, bark-based potting mix with added perlite, moss, or coir. As with many orchids, they grow best when the roots are slightly restricted. Therefore, avoid over-potting or frequent root disturbance. Provide bright light conditions throughout the year. The average temperatures are 25-30°C during day and 16-20°C at night time. Plant requires frequent watering and relatively high humidity during spring and summer months and a slightly drier and cooler conditions in winter - reduce watering and feeding in October, but do not leave plant dry for long period of time.

No pruning required. Remove spent flowers as necessary, but do not cut the whole cane unless completely shrivelled. Oldest canes may be removed as long as there are enough, younger, thick, leaf-bearing canes on the plant.

Propagation by seed is only possible in controlled laboratory environment. Mature plants may be divided when the plant overgrows the pot. Sideshoots (keiki) may develop on older canes - remove and pot them into sphagnum moss when the new roots are at least 2cm long.

May be susceptible to scale insects, aphids, mealybugs and red spider mite.

Generally disease-free.
