About
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.
Permaculture Functions
- Edible: Translucent aril dessert fruit when winter lows cooperate—otherwise sapindaceous experiments mean gambling with nursery receipts.
- Shade Provider: Evergreen canopy for frost-safe tropical rows.
- Wildlife Attractor: Clustered fruit draws birds and frugivores—plan netting or sharing.
Practitioner Notes
- Overfertilized fast growth dilutes flavor and invites sap feeders—lean soil often tastes more like itself.
- Watch the plant’s own signals first—catalog zone numbers do not replace your site’s microclimate truth.
- Notebook one weird year—weather anomalies repeat; memory lies, scribbles do not.
- Sharp tools and clean cuts beat torn stems; disease spores love frayed tissue more than rhetoric.
Companion Planting
- Lychee
- Banana
- Papaya
- Planting as your only fruit tree on frost-prone lots
- Waterlogging — Phytophthora does not send warnings
