Thrives in temperate conditions. Requires a cool winter dormancy period with reduced temperatures.

Requires minimal feeding. Use a very dilute balanced orchid fertilizer only during active growth if desired.
Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water sparingly during the dormant season. Increase watering moderately when actively growing, ensuring the soil remains consistently moist but not waterlogged. Avoid overhead watering to prevent fungal issues.
Reduce watering significantly once the flowering period ends and the foliage begins to yellow.
Pruning is generally not required. Remove dead or damaged leaves at the end of the growing season or after flowering.
Cut back spent flower stalks at their base to maintain a tidy appearance and prevent potential disease spread. Focus on removing any yellowing or dying foliage.
Propagation is best achieved through division of established clumps during the dormant season. Carefully separate the rhizomes, ensuring each division has at least one growing point.
Another method, though challenging and time-consuming, is through seed propagation under specific symbiotic conditions with mycorrhizal fungi.
Repotting is infrequent and typically only done when the plant outgrows its container or the potting medium has decomposed. This is best performed in early spring before new growth emerges.
Use a well-draining orchid mix with good aeration, such as a blend of bark, perlite, and charcoal.
