#1 Pot - 18-24" Shrub
Mountain Holly is an uncommon shrub of wet places but should be planted above the water line when used for naturalizing. It is fairly easy to recognize when flowering or fruiting, with long-stalked bright red fruits or pale flowers with ribbon-like petals. When flowers and fruits are absent, the leaves may help distinguish it: 1 to 2 inches long, hairless, toothless or with a few teeth at the tip, often with a minute point at the apex, and the leaf stalk usually purplish. The related Winterberry (Ilex verticillata) has larger, toothed leaves with hairy leaf stalks and small clusters of short-stalked flowers and fruits. Male and female flowers are usually borne on separate plants. It is a host plant for the caterpillars of the Columbia silk moth, which has an impressive 3.5-inch wingspan.
