These broadleaves are native to humid climates where winters generally are cloudy and plants grow in the sheltered understory of deciduous forests. In addition to climate, Dr. James Klett, Colorado State University Cooperative Extension specialist for landscape plants, says alkaline clay soil is the other strike against growing healthy hollies. It's essential to choose a protected area as a safeguard against high winds and to amend soils with organic matter before planting. Even so, many gardeners may be disappointed by the amount of winter die-back found on their Meserveae hollies. This species produces small, glossy, bluish-green leaves and red berries.
Hollies have separate male and female plants.
Only one male plant is required for a cluster of five female plants. Only one male plant is required for a cluster of five female plants to provide the pollen that will produce berries. The royal pair is reported to bear more abundant fruit. Although not a true holly, grape hollies are more suited to the needs of most Colorado gardeners. This plant bears shiny green, spiny leaves that turn a rich burgundy in the fall.
