This tree casts light shade and has gray to gray-brown bark. It has fragrant flowers in the summer.  Trees do not flower until they reach an age of 3 to 4 years old.  

When grown from seed, they may not germinate for up to one year.  Spending its first winter in a greenhouse will benefit the survival of small trees.  Protection from winter frosts for its first several years outdoors can also help the plant survive.

Each pea-sized fruit contains 3 seeds, which are not likely to ripen in cultivation. They are also fragrant.  An extract from the seed, as well as young leaves is used as a honey substitute.

Typically grown as a tree, it may be grown as a shrub.
