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. Overview Height 10 ft. to 15 ft. Spread 10 ft. to 15 ft.
