The story
Jamun has been grown across India for thousands of years and is sacred in Hindu and Buddhist tradition; the Buddha sat beneath one as a child, and India itself is called Jambudvipa, the island of the jamun tree. The purple fruit stains every mouth in June.
Planting
Full sun, any drained soil, heat; it tolerates drought and flooding once established. Plant a grafted variety; a large, long-lived tree.
Growing
Water young trees, then little. Prune to keep it pickable; it will reach 60 feet otherwise.
Harvest and use
Fruit ripens purple-black just before the monsoon; shake the branches over a sheet. Eat fresh with salt, juice it, and the dried seeds are part of traditional Indian medicine (talk to a doctor before trying any remedy).
What to watch for
Fruit fly, birds and bats, and frost on young trees.
