With the start of the winter season, much of the landscape throughout Northwest Pennsylvania has lost most of its color. Despite this, glimpses of glossy green leaves and red berries are often seen scattering the bottomlands, a signature of the holiday season.
The American Holly (Ilex opaca) is easily identified in the winter months against the contrast of a snowy scene. Inhabiting the understory of forests in moist soils, the tree normally grows between 15 to 25 feet tall but can reach heights of 60 feet. Its stout, stiff branches equipped with spine-tipped leaves is considered the hardiest broadleaf evergreen by many. Female plants possess its notable red berries which are an invaluable food source for wildlife species (but are poisonous to humans).
The tree's beauty and hardiness makes it a desirable native ornamental. There are over 1,000 native and non-native varieties of the species - before planting, make sure to check with a nursery to ensure you are receiving a native American Holly.
