American Holly is the traditional decorative greenery you see every Christmas. It is actually a tree native to the US, and is even the State Tree of Delaware. Its range stretches from the northeastern US, where it grows as a tree, to the tip of Florida, where it is a more shrub like plant. In the Midwest, American Holly is usually found as an ornamental shrub or dwarf tree. Holly is a beautiful and slow growing plant, and over 1,000 different cultivars have been developed. It has a gray, warty bark. Bees will work holly, but it is not a major source of nectar due to it being a mostly ornamental planting. It may be found growing wild in low, moist areas.
