Round-leaf Japanese holly is a handsome evergreen in the holly family (Aquifoliaceae).
Plant in the full sun to partial shade in acidic well-drained soil though it tolerates a wide range of soil types, from moist to dry. It tolerates drought, shade, air pollution, poor soils, sandy and clay soils and is easy to transplant. It has a slow growth rate, is alkaline intolerant and may not thrive in areas with high heat and humidity (USDA zones 8 and 9). This cultivar is male, although female plants may be sold erroneously under this name.
Round-leaf Japanese holly, as with most Ilex crenata cultivars, tolerates heavy pruning and can be grown as a shrub or as a small tree left to grow to its maximum height of 20 feet. Whether as a shrub or tree, its form is dense, upright, and rounded and can be used for topiary.
This cultivar is appropriate for a winter, Asian, English, or drought-tolerant garden.
Diseases, Insect Pests, and Other Plant Problems: Susceptible to pests. Spider mites and nematodes are occasional pests. Alkaline soils will cause the leaves to turn yellow.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common diseases and insect pests.
