The Muckle Plum is an ornamental flowering tree that features clusters of fragrant rose-pink flowers in early spring. Its narrow, pointy green leaves turn a vibrant orange-yellow in the fall. The smooth black bark adds visual interest and dimension to any landscape. A hybrid of the Canadian Plum and Russian Almond, the Muckle Plum is very cold-hardy and fruitless. It thrives in average to moist conditions and is highly tolerant of urban pollution. This tree makes an excellent small accent for any landscape.
