Dendrobium sanderae
A medium to large-sized, epiphytic orchid with upright, cane-like stems up to 80cm long. Each stem (pseudobulb) is covered with alternate, thin, leaf-bearing sheaths. Leaves dark green, are oval shaped, 5cm long. Flowering stems emerge from the upper nodes and tips of mature pseudobulbs and carry two to four, white, long-lasting flowers. Each flower is 7-10cm large, with white petals and sepals. The lip is white with bright green throat and contrasting dark maroon stripes.

How to grow
Cultivation
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 22-25°C during day and 13-16°C at night time. Plant requires frequent watering and relatively high humidity during spring and summer months and a slightly drier conditions in winter - reduce watering and feeding in October, but do not leave plant dry for long period of time. See indoor orchid cultivation
Propagation
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.
Suggested planting locations and garden types
- Houseplants
- Conservatory and greenhouse
Pruning
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.
Pests
May be susceptible to scale insects, aphids, mealybugs and red spider mite.
Diseases
Generally disease-free.
