Native to China, lychee trees have been cultivated there for thousands of years. They have since spread to southeastern Asia, Hawaii, Florida and California. The lychee tree is very attractive, symmetrical, and densely foliated. They have dark green, compound leaves with 4-8 oblong leaflets, which resemble small mango leaves. Lychees do not like wet feet, so be sure to plant your tree in well-drained soil. Trees can also be planted on a mound to ensure proper drainage.
