- Zones 3-9, 11-32, H1, H2
- Full, Partial Moderate Poisonous berries
Many hundreds of species and hybrids exist. Smaller kinds are attractive as foundation plantings or low hedges; larger evergreen sorts make attractive and impenetrable tall hedges or screens. In size, they range from foot-high dwarfs to trees 40–50 ft. tall.
Nearly all holly plants are either male or female, and as a rule both sexes must be present in order for female plants to set fruit. Best bet is to plant a male of the same species as the fruiting females; if you use a different species, berries will form only if both plants flower at the same time.Ilex vomitoria
Most hollies prefer rich, slightly acid garden soil with good water drainage. (A few exceptions are noted.) All appreciate a mulch to deter weeds and keep soil cool and moist. Though plants will grow in sun or part shade, choose a sunny spot for best berry production and most compact growth. Scale can cause problems in all holly-growing areas. Holly bud moth and leaf miner need attention on English holly in the Northwest; for control, employ only products currently registered for use against those pests. Diseases are rarely a problem for home gardeners.
Most hollies tend to be dense and symmetrical. Prune mainly to remove poorly placed, broken, or dead branches. Winter holiday season is a good time to prune, because clipped branches can be used for indoor decoration. You can restore a holly that has become too open or ragged by severely shortening its branches and allowing new growth to fill in. Small-leafed hollies can be sheared into formal hedges or topiary figures.
Evergreen shrub or tree that is native to the southeastern U.S. Takes extremely alkaline soils better than other hollies. Grows to 15–20 ft. tall and 10–15 ft. wide, with narrow, inch-long, shallowly toothed dark green leaves. Often trained as a standard or sheared into columnar form; good topiary plant. Pea-size scarlet berries borne in profusion.
‘Nana’ (Dwarf Yaupon): Grows to 3–5 ft. tall and slightly wider. Refined, attractive; formal appearance when sheared. Fruit is often hidden among the leaves.
‘Pendula’: Weeping branches show to best effect when the plant is trained as a standard. Male and female forms available.
‘Stokes’ (‘Stokes Dwarf’, ‘Schillings’): Grows to 3–4 ft. tall and wide, with closely set dark green leaves. Male.close
