The ovoid, silvery green leaves may be soft and velvety to the touch, but this lamb's ear is actually quite tough. Drought tolerant once established and capable of thriving in dry, rocky soils, 'Silver Carpet' can form a dense, low-growing mound, three to nine inches tall, and up to 18 inches wide. This variety rarely blooms, so pollinators aren't interested in it, nor are deer or rabbits (usually). One caveat - lamb's ears fare better in sunny locations where the leaves can dry out between watering. Humidity and too much moisture may cause the leaves to rot, and though evergreen here in the Pacific NW, 'Silver Carpet' may "brown out" in the winter.
