Ilex 'Savannah'

'Savannah' holly is a female evergreen small tree in the Aquifoliaceae  (holly) family.  It grows up to 30 feet tall and 8 feet wide as it matures with a rapid growth rate. It is loosely pyramidal, upright, and dense when sited in a sunny location, but more open when sited in partial shade. This plant is a heavy fruiter, producing red berries that persist through winter and contrast well with the pale green leaves.

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.  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.

Plants are dioecious (separate male and female plants) and, in order to set fruit, this female plant will need a nearby male pollinator. Plants can suffer from the cold in USDA Zone 5 and below.  This tree is mildly resistant to damage by deer.

Use in a pollinator or winter interest garden, planted along a slope, lawn area, or walkway.  Its mature height works well for the back of a border as a hedge, barrier or screen.

Insects, Diseases, and Other Plant Problems:  Insects can include holly leaf miner, spider mites, scale, whitefly, and spittlebugs. 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.
