Like the name suggests, hummingbirds love Hummingbird Mint (Agastache foeniculum)! The purple flowers are a nice change from the red blooms typically used to attract hummingbirds and can add a lot of visual interest to any garden. Bonus? The plant's leaves give off a mild licorice scent when jostled. Hummingbird Mint is drought-tolerant, so it can handle hot, dry summers, and is hardy in Zones 4 – 8.
