Dimocarpus longan is lychee's slightly less famous cousin: translucent aril around a jet-black seed that literally looks like a dragon's eye if you squint poetically. Evergreen tropical tree with glossy compound leaves and panicles of tiny flowers that become clustered fruit. Marginal except in warm microclimates; young flushes hate cold snaps. ☀️💧 Sun and Water Requirements: Full sun for commercial-level fruiting; afternoon shade acceptable in brutal heat. Deep, fertile, well-drained soil with steady moisture in fruiting season. Mulch and wind protection for establishment. ✂️ Propagation: Air-layering and grafting for true-to-type cultivars. Seeds grow but produce variable, long-juvenile offspring. 🌾 Harvest / Best Use Timing: When skin turns tan/leathery and fruit separates cleanly — overripe loses snap.
