Longan
Lychee's easier-going cousin. Reliable clusters of sweet, musky fruit on a tough tree.
Dimocarpus longan
The lychee's easygoing cousin, with clusters of sweet, translucent fruit and better reliability than lychee in our climate.
Why it works here
Longan is a great fit for the Treasure Coast and, in many ways, an easier bet than its famous cousin the lychee. It is a big, handsome evergreen with dark foliage that produces hanging clusters of brown-shelled fruit with sweet, juicy, translucent flesh around a single seed. It tends to fruit more regularly and prolifically than lychee, and mature trees are cold hardy enough to shrug off our normal winters. The one honest quirk is that even longan can be erratic, some years it bears heavily and others it takes off, so think of a bumper crop as a gift, not a promise.
Care
Plant it in full sun in well drained sandy soil, and water regularly through the spring and summer bloom and fruiting period, easing back the rest of the year. It does not want soggy roots. Mulch well, keep it off the trunk, and feed with balanced organic fertilizer during the growing season. It gets large, so site it away from the house and power lines, or commit to pruning it down to a manageable, easy-to-harvest size. Protect young trees from cold for the first few winters.
Common problems
Erratic or alternate bearing: some years are heavy, some are light. This is normal for longan. Steady care and not stressing the tree helps, but expect year-to-year swings.
Branch breakage: heavy fruit clusters can snap limbs. Prune for strong structure and thin or prop heavy loads.
Gets big: it can outgrow a small yard. Keep it in bounds with regular pruning, which also makes harvest far easier.
Common questions
How is longan different from lychee?
Same family and similar sweet translucent flesh, but longan has a brown, smoother shell and a slightly muskier, honeyed flavor. Around here longan tends to fruit more reliably than lychee, which is why a lot of growers prefer it.
Why did my tree fruit heavily one year and barely the next?
That is longan being longan. It is known for uneven, on-and-off bearing. It is not something you did wrong. Consistent care evens it out somewhat, but expect good years and light years.
Will it handle our winters?
An established tree, yes. It is hardy enough for our normal cold, taking brief dips into the mid 20s once mature. Young trees are more tender, so protect them the first few years.
