Pineapple mint is a variegated cultivar of apple mint (Mentha suaveolens). It features attractive, variegated leaves, usually with white margins, on plants that grow up to a foot (31 cm.) tall. The leaves are bumpy and hairy and the white edging can make them look as though they are sporting a ruffle. White or light pink flowers bloom on small spikes at the top of the plant in summer. The flowers attract a wide variety of pollinating insects, including bees and butterflies. Deer dislike strong fragrances and hairy leaves, so they have two reasons to dislike pineapple mint.
