Foliage is white centred with a green margin in spring, becoming all green by midsummer. Heavily rippled leaf margin 1/8" wide on leaves measuring 3" long x 1 1/2" wide; leaf blade also very narrowly elliptic. Bright purple flowers in August on 20" scapes. Makes a nice clump once it gets established. If you give it a bit more sun, the leaves become more elongated and rippled.
