Seaside Primrosewillow     Ludwigia maritima

The Seaside Primrosewillow (Ludwigia maritima) is a member of the Evening Primrose family (Onagraceae).  Other common names for this plant are Seaside Ludwigia and Harper’s Seedbox.  The habitat for this native perennial herb includes moist areas like ditches, low pinelands, marshes and swamps.  It is found in the southeastern coastal states from Louisiana to North Carolina.  In Florida, it is found throughout the state.  It is interesting to note that 82 species of Ludwigia have been identified throughout the world and 30 of those species have been found in Florida.

The slender branching stems of these plants can grow to a height of 2 to 3 feet and are usually reddish to golden in color.  The linear or lanceolate shaped leaves are attached alternately along the stem.  They average 1 to 3 inches in length and can be up to 1/2-inch wide.

This plant produces showy yellow flowers that appear axillary along the stem, that is at the junctions of the stem and a leaf.  The flowers have four petals and four sepals and are about 1-inch in diameter.  In the center of the flower is a large stigma surrounded by four stamens.  In Florida, the flowers bloom from May to November.
