There are several prostrate, mat-forming or erect summer annual species of Ludwigia (Onagraceae) that are common in areas that remain wet for extended periods of time. Stems are succulent, often red in color. Leaves are also often reddish in color. Flowers are inconspicuous on the prostrate species but bright, showy yellow on several upright species. Prostrate species are more common in gravel areas but may spread to pots. Water purslane encroaches on containers from nearby infestations. Improved drainage can reduce the habitat available for establishment of this species, thereby reducing the ability of this weed to spread to container nursery crops. No herbicide efficacy data are available. [TOP]
