Ilex Verticulata, most often called the black alder or winterberry, is a type of holly popular among bird watchers. It produces small berries in the winter that are irresistible to wildlife. A small tree-like shrub, the black alder performs well in overly-watered or poorly drained soil.
Preferring full sun, the Ilex Verticulata doesn’t grow well in shaded areas, though it can handle limited partial shade. It has a mature height of between six and 10 feet, making it a great ornamental shrub. Blooms in early June with berries that provide color throughout cool winter months.
