Consider Planting American Holly in Your Yard


American Holly or Ilex Opaca:

American holly is a deep-woods species and mid-story tree that is the state tree of Delaware. The tree was noticed by the Pilgrims who landed in North America the week before Christmas in 1620 on the coast Massachusetts. This evergreen with prickly leaves and red berries reminded them of English holly which was a symbol of Christmas England and Europe. Ilex opaca is the only native North American holly that attains tree size.

Habit and Range:

American holly is slow growing but well worth the wait. Actually some cultivars approach 6" of growth per year. American holly grows into a small to medium tree of about 40' to 50' tall and optimum growth can be encouraged on moist, highly organic, acid and well drained soil. This holly has a comfortable north-south range in North America that goes from Massachusetts to Florida. The tree needs to be protected from drying winter sun and winds.
