Dendrobium Mesangnil Blue x Rania Ayu

Dendrobium Mesangnil Blue × Rania Ayu is an unregistered, modern Thai-style antelope hybrid combining two well-known curly‑petalled “blue” dendrobiums. While neither parent is formally documented in public hybrid registries, both are widely sold in Southeast Asia and Indonesia as curly, twisted-petal antelope types with blue–purple tones. The cross is therefore predictable in its phenotype: curly antelope form, strong blue–violet colour, and vigorous warm-growing habit.
Typically, white to pale lavender with a deep purple/blue centre.
Often used in breeding for clean form and colour stability.
Images show a broad, rounded flower with a purple lip and white margins.
