Cultivar, sold under the trade name "Silk Stockings".
"Created by Aquascapes Unlimited, Inc. and chosen for its fine, green veins over bronzy-red foliage. The new leaves are particularly lovely, being dark reddish with light veination. For best color, avoid hot sunlight. Morning sun, followed by dappled sun or very bright shade is best, especially in warmer climates. Like all Sagittaria, Silk Stockings™ grows best in calm, shallow water, about 1/2 inch to 2 inches deep. The dormant tubers, which form in the fall, are edible and important wildlife food, giving rise to the name "Duck Potato". Some species were known to the Native Americans as "Wapato"."
