Botanical Name: Ilex verticillata EYE-leks ver-tih-sih-LAY-tah Common Name: Black alder, Winterberry Genus: Ilex
This plant is a suckering shrub or small tree with toothed, pointy, bright green leaves. It bears white flowers in spring, which are followed by spherical dark red to scarlet berries that persist through the winter. Some fruit ripens to yellow or orange.
Care: Adaptable to wet soil conditions and likes full sun to partial shade. Use as specimen tree or in a woodland garden. Plant or transplant in spring. Grow in moderately fertile, humus-rich, moist but well-drained soil. Hollies are dioecius, so a few male plants are needed for a female plant to produce berries. Dwarf male cultivars are available for this purpose.
Propagation: Semi-ripe cuttings in summer or early autumn.
Problems: Young shoots are susceptible to aphids. Phytophtora root rot sometimes occurs.

Plants grow to about 5 feet tall and 8 feet wide.
