Miss Cortney American Holly Foliage

American holly, English holly (Ilex aquifolium),  and winterberry (I. verticillata) are all species having male and female flowers borne on separate plants (dioecious). Pollen transfer from a male to a female plant is known as cross-pollination, usually accomplished by insects including bees, wasps, ants, yellowjackets, and night-flying moths. If a holly plant fails to produce berries, it is either a male, or an unfertilized female plant. To insure good berry production, it is suggested at least one male plant for every three females be planted within 200 feet.

Miss Courtney American Holly

Since the settling of North America, American holly has become one of the most valuable and popular trees in the Eastern United States, known  for its evergreen foliage and bright-red berries. American holly is the hardiest known broadleaf evergreen tree, with cultivars naturalized in Ohio down to -20 degrees F, and native populations in the mountains of West Virginia where the average low temperature is -10 degrees. Holly grows in almost any soil, from sandy Atlantic beaches to thin mountain soils, to dry gravelly soils inland. However, the largest holly trees are found in the rich bottom lands and swamps of the coastal plain in New Jersey [1].
