Short Description

A small succulent flowering perennial that grows rapidly to form an extensive lush-green "carpet" that floats on freshwater or may be submerged. Growth can extend from margins of sheltered waterbodies to completely cover the water surface with tangles of stems and shoots. Plants may range from 10-130cm in length. In deeper water, plants are more elongate and have narrower leaves. Flowers are <4mm and white to pale pink.
