Kohala Longan

Dimocarpus longan 'Kohala'

fruit

Kohala is the longan that built backyard longan growing in Florida - the overwhelming majority of trees are this single dependable cultivar, introduced from Hawaii in the 1950s. A close relative of the lychee, longan hangs its tan, thin-shelled fruit in big drooping clusters; peel the shell and the translucent flesh is sweet and aromatic with a distinctive musky-honey flavor, around a single dark seed that gives the fruit its name (dragon eye). The tree is a large, vigorous, rounded evergreen that bears more reliably than most lychees, making it a productive and ornamental shade tree for warm, subtropical gardens.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Sweet Potato: A living mulch that shades the longans surface roots and crowds out weeds beneath the canopy
• Comfrey: Deep roots mine minerals; the leaves are chopped and dropped as a rich mulch at the drip line
• Lemongrass: A fragrant clumping border that shares the warm, well-drained site and helps deter some pests

• Anthracnose →

  A wet-weather fruit and leaf fungus - prune for airflow, avoid overhead watering, and clear mummified fruit

🌾 Harvest & storage

Air-layered or grafted longans begin bearing in about 2 to 4 years. Kohala blooms in late winter to spring and ripens from mid-July into early September, peaking in August. The fruit ripens only on the tree and does not sweeten after picking, so taste a few before harvesting whole clusters when the tan skin is full-colored and the flesh is sweet. Cut the bearing stem behind the cluster. Eat fresh, refrigerate for a week or two, or peel and freeze the flesh.
