Blue Waterleaf, Ovate False Fiddleleaf, Hairy Hydrolea
Hydrophyllaceae (Waterleaf Family)
Synonym(s): Nama ovata
USDA Symbol: HYOV
The sprawling, sturdy blue waterleaf plant, which grows to 3 feet tall, is spiny and covered with rough hairs. Several stems grow from the base and are branched in the upper portion. Leaves are 1-2 1/2 inches long and 1 inch wide, alternate, undivided, and unlobed. There is a prominent spine on the stem just below the leaf. Many flowers and buds grow in clusters at the ends of the stems. Flowers are bright blue or purplish, 1 inch across, funnel-shaped, opening into 5 broad petal-like lobes. The conspicuous purple stamens extend beyond the petals. Blue waterleaf tends to form large colonies around the edge of lakes, ponds, and streams, and may stand in water for weeks without apparent damage (248).
