This corm forms a 6 by 9-inch mound with heart-shaped leaves marked with dark green and silver-white. It blooms in colors ranging from white to reddish-pink to purple in late winter/early spring. Cyclamen coum clumps go dormant in the summer and prefer to be very dry during this rest period. This can be accomplished by planting them under the canopy of trees. It prefers rich, well-drained soil in light shade.
