American bittersweet is a shrub that can climb like a vine.

American bittersweet is a fast growing shrub that climbs and is native to North America, found east of the Rocky Mountains. It’s important to keep an eye on it so that it doesn’t take over other plants.

It climbs by twisting around its support and can grow as high as its host. The woody stems can strangle trees it grows on. Its deep green, shiny leaves are oval and pointed, turning yellow before dropping in the fall. The blooms are small and appear on separate male and female plants. If pollinated, the female flowers produce striking orange berries in the fall that last through much of the winter.

This plant can grow in nearly any soil that is not constantly wet. It needs full sun or partial shade to start growing. Plant at least one male for every three females to ensure pollination. Prune heavily in early spring to stimulate flowering and remove unwanted growth.

American bittersweet is often used to cover ugly fences or rock piles. It can be trained to climb arbors, trellises, and mature trees, but avoid letting it grow on young trees or shrubs because the twisting stems can cut off their sap. The seeds are poisonous to humans but do not harm birds that eat them in winter. The fruit-bearing branches are often used for winter decorations.

The Loesener bittersweet (Celastrus Loeseneri or C. Rosthornianus) is similar but not as hardy or attractive. Asian bittersweet (C. Orbiculatus) is an invasive weed and should not be planted.
