This easy to grow perennial is perfect for the hot, full sun garden, blooming in July and August with bright, cheerful rosy purple 2" round flowers atop a mound of neat, tidy, bright green strappy foliage that, when crushed, has the fragrance of onions. Deer hate the onion scent. Some designers are using this plant in gardens to keep the deer away from the rest of the plants in the garden. Loves hot dry conditions.
