General Culture:
Easily grown in average, medium, well-drained soils in full sun to part shade. Best yellow foliage color for 'Golden Gem' occurs in full sun. Tolerant of a wide range of growing conditions, including clay soils and urban pollution. Prefers light, moist, acidic soils with good drainage. Chlorosis (leaf yellowing) may occur in alkaline soils. Japanese hollies are dioecious (separate male and female plants). 'Golden Gem' is an all-male cultivar which will not produce fruit. May not be reliably winter hardy throughout USDA Zone 5 where it should be grown in a protected location with a winter mulch.
Noteworthy Characteristics:
'Golden Gem' is a dwarf, evergreen Japanese holly cultivar which, as the cultivar name suggests, is noted for its unusual golden foliage. It grows somewhat slowly in a flat-topped mound to only 2' tall. Features elliptic to obovate, golden yellow leaves (typically 1/2 to 1 1/4" long). Japanese holly foliage somewhat resembles boxwoods more than hollies. Non-showy, tiny, greenish-white flowers appear along the stems in the leaf axils in late spring.
Problems:
No serious insect or disease problems. Spider mites can be troublesome. Nematodes are a problem in the South.
Uses:
Rock garden. Small hedge. Incorporate into a foundation planting.
