Noted for its showy coral bark and fall color, award-winning Acer palmatum 'Sango-kaku' (Coral-Bark Maple) is a large deciduous shrub or small tree that is highly desirable. In the fall, the delicate 5-lobed leaves which open pinkish-yellow, and mature to light green in summer, warm up to a soft yellow in fall before they shed to the ground. As they fall, they expose the bright, coral red bark on young twigs and branches, adding a much needed splash of color in the winter landscape. In spring, the small, reddish flowers are pretty, but not showy. They give way to samaras that ripen in late summer to fall. Slow-growing, this maple tree enjoys an upright, vase-shaped habit and makes an outstanding four-season tree that is enjoyed by all gardeners as it graces the landscape. A must for those who appreciate winter bark interest!
