Why it's a standout: At the height of its summer bloom, you'll smell this spicy-scented shrub before you spot it. Most varieties flower white, but for a splash of pink, try 'Ruby Spice' (shown). This native lures birds, bees, and butterflies, turns gold in fall, and grows, on average, 5 to 8 feet tall and 4 to 6 feet wide.
What it needs: Full sun to partial shade; prefers average to moist soil but tolerates clay and soggy conditions
Zones: 3 to 9
