ilex vomitoria 'Nana' Dwarf Yaupon Holly1

Edward F. Gilman2

Introduction

The symmetrical, dense, rounded form of dwarf yaupon holly requires only infrequent pruning to maintain its 4- to 6-foot height and spread (Fig. 1). Unpruned plants eventually grow 7 to 10 feet tall and slightly wider. Roots produce sprouts at the edge of the canopy, producing dense thickets with time. Ideally suited as a low-growing foundation plant, dwarf yaupon holly is also excellent as a tall ground cover for a large-scale commercial or industrial landscape. It can be sheared into a formal hedge or into any of a number of topiary shapes. Most people “meatball” the plant into a globe. The small, gray-green leaves of 'Nana' have no spines, and this cultivar of a female plant rarely produces berries. Leaves are slightly larger than on 'Shellings'.

Use and Management

Foliage of dwarf yaupon holly


[Click thumbnail to enlarge.]
Growing well in sun or light shade in soils from dry to wet, dwarf yaupon holly withstands drought when established and is highly salt-tolerant, making it ideally suited to seaside plantings. It is a selection of the native yaupon holly, which grows naturally without irrigation on the dunes along the Atlantic Ocean. Growth rate is slow to moderate. Space plants 4 to 5 feet apart in a mass planting. Be sure to set plants several feet back from a walk, driveway or lawn area, because plants grow wider than tall and often require pruning to control their lateral growth. If you need to prune in this manner, be sure to leave the bottom of the plant much wider than the top so that lower foliage is left on the plant. If you attempt to shear vertically, the lower branches will be shaded and will often lose foliage. This will give the shrub an unsightly, dark, leafless bottom.

Propagation is by cuttings.
