American Bittersweet

Celastrus scandens

The Story

Plant Bio

Celastrus scandens, American bittersweet, is a woody twining vine native from central and eastern Canada through the northern, eastern and central United States, climbing twenty to twenty-five feet. Small greenish flowers in spring are easy to miss; the point is the autumn fruit, orange capsules that split to reveal scarlet seeds and persist through winter. It is dioecious, so fruit needs both sexes.

Its terminal flower and fruit clusters are the reliable way to tell it from the invasive Oriental bittersweet, which fruits along the stems at the leaf axils — a distinction worth learning, because the Asian species is displacing this one across its range. The twining stems can girdle and kill young trees, so give it a fence or arbour rather than a sapling.

Uses & Benefits:

Ornamental UsesOrange capsules splitting to scarlet seed in autumn, holding on through winter and prized for cut arrangements.
Practical UsesCovers a fence or arbour quickly and tolerates dry soil and salt.
Ecological BenefitsFruit is an important late-winter food for songbirds when little else remains.

  6. Prune in late winter to control size.

Pro Tip

Buy sexed plants and check the fruiting pattern — terminal clusters mean American, axillary clusters mean the invasive Oriental species.
