Diospyros ebenum, commonly known as Ceylon Ebony or Indian Ebony, is a slow-growing tropical timber tree native to southern India, Sri Lanka, and Indonesia. The species produces the finest jet-black heartwood used for centuries in musical instruments, chess pieces, and luxury furniture. Ebony seeds are recalcitrant (short-lived) and must be sown fresh immediately after collection to achieve optimal germination rates of 85% within 17-65 days.
Before sowing
Remove fleshy pulp from fresh seeds immediately and sow fresh. Seeds have very short viability; sow as soon as possible after collection. Fresh seed sown one day after collection showed 85% germination rate within 17-65 days.

What to expect
Tips
Collect fully ripe fruits and extract seeds immediately. Remove all fleshy pulp thoroughly as it contains germination inhibitors. Soak seeds in cold water for 24 hours before sowing. Sow in a shaded nursery position using a 3:1 soil-to-fine sand mixture in well-draining medium. Maintain high humidity and consistent moisture—seeds are very sensitive to desiccation during germination. Keep soil temperature at 25-30°C for optimal germination. Seedlings grow very slowly and develop long taproots early; provide deep containers with excellent drainage. Maintain shaded conditions during early growth. Acclimate seedlings gradually to direct light before transplanting to permanent locations.
