Gardening with Tropical Fruit
The Indian Jujube
By Gene Joyner, Extension Agent
Palm Beach County Cooperative Extension Service
If you’re looking for a medium sized evergreen tree
that fruits heavily, you might consider planting the Indian
jujube (Zizythus mauritiana) which grows to about 35 to 40
feet at maturity. This tree is from the Asiatic tropics and
has leaves which are two inches in length which are dark
on top and lighter colored underneath.
Single or paired thorns are usually present at the leaf
bases so be careful with trimming trees or harvesting the
fruit. Numerous yellowish-white flowers are borne in clusters
at the leaf axils and the large numbers of fruit are orange
to brownish in color and may be rounded or oblong, about
one inch in diameter.
A layer of edible pulp surrounding the hard central seed
is highly prized and some have the flavor of a high quality
apple. Fruit can be eaten fresh or if allowed to get over
ripe often it is said that they somewhat resemble dates in
flavor.
Trees are easily propagated by seed, however, it takes at
least two years before they begin to produce fruit. Grafting
and air layering of desired clones is very easy and they
can also be rooted from cuttings under mist in some situations.
Trees are problem free and grow over a wide range of soil
types. If they are close to the ocean, salt spray may burn
leaf margins, but doesn’t keep the tree from fruiting.
Trees generally are quite hardy in most typical winters,
however, hard freezes can injure tender branches.
Growth rates of trees are about 3 to 5 feet a year when
young and in some areas they are kept as large shrubs rather
than allowed to grow into trees and they still produce adequate
quantities of fruit.
A closer related jujube, the Chinese jujube, needs a little
bit more cold weather than south Florida since it is a tree
from temperate climates. Those produce higher quality fruit
than the Indian jujube in most cases, but tend to root sucker
and can be a nuisance with a lot of unwanted new trees.
Indian jujube can also be fruited as a container plant in
a large container if you don’t want to put it outside
into the landscape.
