Scientific name: Heteranthera limosa (Pickerelweed Family: Pontedericaceae)
Ducksalad is an annual to perennial aquatic plant. In California it is found mostly in the Sacramento Valley. Typically it grows in water. Seedlings are submerged and the mature plant emerges from the water's surface. Ducksalad may grow on mud banks where water has receded. It inhabits ditches, ponds, lake margins, and is an early season problem in rice, primarily in open water.
The seedling is hairless, submerged, and typically forms a rosette of narrow ribbonlike leaves.
Older juvenile plants may have floating leaves.
The mature plant is erect and grows to over 1-1/2 feet (about 0.5 m) with bright, waxy green, oval-shaped leaf blades that may be submerged, floating, or held above the water's surface. Sometimes plants develop a creeping horizontal stem.
Flowers bloom from April through July. The single, showy flower has a long stalk and opens above the water. It has six petals arranged in a narrow star shape that may be white or bluish purple.
Fruit consist of erect capsules that are about 4/5 of an inch (2 cm) long.
Seeds germinate only in saturated soil.
Reproduce primarily by seed.
