'Savannah' is a female cultivar of the natural hybrid Ilex × attenuata. It is a member of the holly family (Aquifoliaceaee). It was discovered by W. H. Robertson, Commissioner of Parks in Savannah, Georgia in the 1960s.
The 'Savannah' Holly grows best in acidic, medium moisture, well-drained soils in full sun to part shade. Although the best fruit production occurs in full sun, these plants do well with some afternoon shade in hot summer climates. You should site the plant where it can be protected from cold winter winds and the soil is well drained. Mulch helps retain soil moisture and deter weed growth. Prune in winter to maintain a desired size, although keep in mind that the plant flowers on new growth. Hollies are dioecious (separate male and female plants) so, to set fruit, female plants will need a nearby male pollinizer. Plants can suffer from the cold in USDA Zone 5 and below.
It typically grows as a 20 to 30-foot tree, 15 feet wide, with a narrow, columnar to open pyramidal form. The 4-inch long leaves are sparsely spined, light green, elliptic to ovate, broad and paper thin. Abundant, pea-sized, red fruits appear in fall and persist over winter. The greenish-white spring flowers are inconspicuous. ‘Savannah’ is a very popular landscape plant and makes a great landscape choice.
Insects, Diseases, and Other Plant Problems: May be affected by leaf spot, leaf rot, tar spot, and powdery mildew. There can also be issues with leaf drop, leaf scorch, and chlorosis. Insects can include holly leaf miner, spider mites, scale, whitefly, and spittlebugs.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common diseases and insect pests.
