Pineapple Mint (Mentha suaveolens 'Variegata') is a perennial with light-green, cream-edged, textured leaves that have a very pleasant pineapple flavor. (It's said to go well in punches and fruit drinks.) It likes partial shade and average soil and grows to 18 inches tall and 12-15 inches wide. It also bears very fragrant white flowers and attracts bees, butterflies, and birds. Like all mints, it can be invasive in the garden.
