Its foliage is typically green. It has white flowers which appear in mid spring. Black fruit, which may be edible (but consult a reliable source before eating), is produced in great abundance from spring to summer.
It grows rapidly in thickets to a height of about 5 feet with roots at least 8 inches deep, and has a lifespan of 100 to 250 years. It will readily resprout even if cut down to the ground.

The USDA believes this plant to be unavailable for purchase. It is propagated by the following methods: bare root, container, cuttings, seed, sprigs. Seeds will be more successful if cold stratification is used. Typically, this plant will seed itself at a slow rate, and new seedlings will have a low chance of success compared to other plants of this type.
