Ilex opaca 'Clarendon'
American Holly (Ilex opaca 'Clarendon') is a broad-leafed evergreen tree with bright green foliage and a rich red-brown bark. It has sharp, spiny leaves that remain throughout the winter and masses of white berries in the fall. The small, but long-lasting, white flowers are fragrant and attract pollinators in the spring. It is native to the Eastern United States and Canada, and is best grown in acidic, moist and well-drained soils. It is often used as a specimen tree in smaller landscapes and can tolerate challenging weather conditions. Pruning and shaping may be needed to maintain its shape over time. American Holly is an excellent choice for adding a touch of winter color to any garden.
