This beautiful wildflower can be found at the edges of ponds, creeks and swamps, and are found in the wild from South America to the United States. Flowers are a delightful 1 inch (10-20 mm.) sunflower yellow. These plants are easy to grow, just put them into a pond. Do not expect a large bush, Water Primrose is a very vigorous growing plant that carpets the edges of ponds with creeping or floating, branching stems, which grow up to a foot high, covered with glossy, oval leaves, which grow up to an inch in length. The leaves are light green on top and creamy green beneath. The foliage that grows above the water may be darker green tinted with red. It produces cup-shaped, yellow flowers that persist all summer long . They begin blooming in June and finish up in September, making it a very long bloomer. and can be quite aggressive in some areas.

This plant is extremely invasive and is best suited for larger ponds unless one has the time to keep it trimmed back. It has a tendency to take over the pond as the stems creep into the water.

General Culture: Grow these plants in 1- to 5-gallon containers, depending on their eventual height, filled with rich loam or clay-based soil. Primrose Creepers need shallow water, they tolerate full sun and no drainage.

Propagation: These plants may be divided or rooted stem cuttings may be planted.
