- Description
-
‘Compacta’ is a cultivar of Japanese holly (Ilex crenata) and member of the holly family (Aquifoliaceae). It is a low, compact, globose version of Japanese holly known for its small black fruit, rich dark green foliage, and spreading habit. There are several plants marketed under this cultivar name. The best-known was introduced by Tingle Nursery and is male.
‘Compacta’ holly likes full sun to partial shade. It is tolerant of poor, sandy soil but prefers clay. It is intolerant of alkaline soil and drought. It is easy to transplant, is urban tolerant, but has pest problems. It may not thrive in areas with high heat and humidity (USDA zones 8 and 9).
‘Compacta’ is an evergreen shrub that grows to 6 feet high and wide, making it a good choice for a tall ground cover that works well as a foundation plant, hedge, or in small groups in a shrub border. Compact Japanese holly is also good in formal gardens and, because it tolerates pruning, for topiary. It is ideal for an English, Asian, or winter garden.
Diseases, Insect Pests, and Other Plant Problems: Can be susceptible to pest problems. Spider mites and nematodes are occasional pests. Alkaline soils will cause the leaves to yellow.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common diseases and insect pests.
