Plant Description

Paradise tree is an evergreen, small to medium-sized tree that grows up to 20 m high, with a trunk 50 to 80 cm in diameter with a narrow crown, well-developed root system, and straight, cylindrical bole. Bark is smooth and green when young, eventually turning light brown to gray, resembling the skin of a cantaloupe. The twigs of tree-of-heaven are alternate on the tree, stout, greenish to brown in color, and lack a terminal bud. They have large V- or heart-shaped leaf scars. The twigs easily break to expose the large, spongy, brown center, or pith.

Leaves

Tree-of-heaven leaves are pinnately compound, meaning they have a central stem in which leaflets are attached on each side. One leaf can range in length from 1 to 4 feet with anywhere from 10 to 40 leaflets. The leaflets are “lance” shaped with smooth or “entire” margins. The leaflets are up to 10 cm in length, dark green above, lighter below, with an entire margin and rounded leaf apex. At the base of each leaflet are one to two protruding bumps called glandular teeth. When crushed, the leaves and all plant parts give off a strong, offensive odor.

Flowers

Flowers are arranged in at branch-ends and in leaf-axils, in panicles. The calyx has 5 unfused, greenish sepals. The flower has 5 free yellowish-white overlapping petals. Male flowers have 10 stamens and no ovaries. Female flowers have 10 nonfunctional stamens and 5 unfused ovaries each with a single locule and seed. Occasionally there are perfect flowers produced on either the staminate or carpellate trees. Flowering normally takes place from

Fruits

Fruit is an oval purple/black drupe at maturity. The fruits can be eaten raw but are of inferior quality. Seeds on female trees are a 1-to-2-inch-long twisted samara, or wing. There is one seed per samara. The samaras are found in clusters, which often hang on the tree through winter. The seed produces edible oil used in the preparation of bakery products and for industrial purposes. Seed shells can be used in the manufacture of particle board, activated charcoal, or as fuel
