Gardeners' Notes:

Grows perfectly well in full sun on acid soil in the Arnold Arboretum, Boston Z6a.

It's said that the "fruit" (actually the swollen part of the stem just below the flower/seed) ripens close to frost or just after.

I planted a foot- tall tree last year in native soil of pH 5.5. It is now 3 ft. tall and reasonably healthy. The leaves are a little pale, but should darken after better nutrition, and after the roots grow deeper.

Positive Treeguy On Nov 13, 2005, Treeguy from Charleston, SC wrote:

I grew this plant in Florida and I am now growing as part of the inventory of my new Nursery in Columbia, SC. This lovely little tree has drawn rave reviews to people that see it. It has lovely bright green leaves that remind me of those of a Basswood(Linden) which sometimes in fall may turn a muted yellowish color. The bark is smooth on young trees and become very distinctive on older trees with alternanting ridges of light gray and dark gray. Grows fairly fast as a young plant. Should be a very good honey plant!

A small tree form Japan. I have not grown this species but might try sometime. According to Simon and Schuster's Guide to Trees the swollen twisted stalks that bear the tiny fruit are edible and said to taste vaguely like raisans.

Neutral MotherNature4 On Apr 19, 2004, MotherNature4 from Bartow, FL (Zone 9a) wrote:

The raisin tree is an attractive deciduous tree when it is in leaf and flower, however, it is very trashy when the fruit falls to the ground. Seedlings sprout easily under the large tree.

If anyone knows how to use the fruit, it would be nice to be able to do something with the crop.

Glossy, oval leaves; creamy, slightly showy, fragrant flowers in 3" clusters. Average dimensions at
maturity are 25' tall and 20' wide. "In leaf, form, and texture, the plant resembles the American
basswood...and, like the basswood, possesses a beauty that is rather striking" .
The tops of unestablished raisin trees may die back in the colder winters. They grow back during the
summer. The raisin tree is usually propagated by seed, or softwood or root cuttings.
