They are herbaceous annuals or perennials. Typically they have square stems, narrow stalkless leaves, and spikes of star-shaped flowers in shades of purple, pink and white. They are especially associated with boggy areas, river banks and ponds, though in cultivation they often tolerate drier conditions. The species L. salicaria (purple loosestrife) and L. virgatum are found in cultivation.[3]

Some species of Lythrum are heterostylous, such as the tristylous (occurring in three forms) L. salicaria.[8]
Lythrum species are used as food plants by the larvae of some Lepidoptera species, including the small emperor moth, the engrailed, the Hebrew character, and the V-pug.
The genus Lythrum is listed as a noxious weed in Michigan, North Carolina, and Wisconsin.[9]
So far the oldest evidence of Lythrum is fossil pollen from the early Campanian, 82-81 Ma of Wyoming.[10]
