Anise-scented and easy-growing, red hyssop adds texture and a splash of silver to your garden. For extra variety, look for selections with red, apricot, salmon, or magenta blooms. You're not the only one who will love this summer-blooming perennial; it's sure to attract hummingbirds and butterflies, too. (But happily, not deer or rabbits! They avoid it because of its aromatic foliage.)
