The Onagraceae are a family of flowering plants known as the willowherb family or evening primrose family. They include about 650 species of herbs, shrubs, and trees[3] in 17 genera.[4] The family is widespread, occurring on every continent from boreal to tropical regions.

The family includes a number of popular garden plants, including evening primroses (Oenothera) and fuchsias (Fuchsia). Some, particularly the willowherbs (Epilobium), are common weeds in gardens and rapidly colonize disturbed habitats in the wild. One such species is fireweed (Chamaenerion angustifolium).

The family is characterised by flowers with usually four sepals and petals; in some genera, such as Fuchsia, the sepals are as brightly coloured as the petals.

The seeds are generally very small. In some genera, such as Epilobium, they have tufts of hairs[5] and are dispersed on the wind. In others, such as Fuchsia, the seeds develop in juicy berries dispersed by animals. The leaves are commonly opposite or whorled, but are spirally arranged in some species; in most, they are simple and lanceolate in shape. The pollen grains in many genera are loosely held together by viscin threads. Most bees cannot collect it, and only bees with specialized morphologies can effectively pollinate the flowers; nearly all bee taxa that visit the flowers are oligoleges specialized on the family Onagraceae.

The family was named after the genus Onagra (now known as Oenothera) in 1836 by John Lindley in the second edition of A Natural System of Botany.
