Floating Primrose

(Ludwigia peploides)


Floating primrose leaves emerge from the water’s surface and the plant blooms with five-petal yellow flowers.


Floating primrose leaves are green, one-half to three and a half inches long, and one-fourth to one and a half inches wide. The leaf stalk can be as long as the leaf is wide. Yellow flowers have five round petals around a yellow center. Stems branch and can grow to two feet tall.

There are many types of primrose; some grow in dry conditions and some grow in wetter areas. Floating primrose is not native but there are other types of primrose that are native. Primrose is a perennial plant with yellow flowers that blooms spring to fall; some varieties have hairy stems. The leaves are often sword- or elliptical-shaped; floating primrose floats as mats on the surface of the water.


Floating primrose grows in the lower two-thirds of the United States.
