Leaves: Smooth-edged, pale green, usually alternate, shaped like a grass blade, 4-10" (10-26 cm) long.

Flowers: Soft and hairy, with two lips, purple, lavendar, pink, or white, or some combination thereof, with yellow and purple markings in the throat. Margins are jagged and wavy. Flowers are fragrant, and up to 1½" (4 cm) around. Flowers appear from May to September.
