Epilobium minutum is a species of willowherb known by the common names little willowherb, chaparral willowherb and desert willowherb.[1] It is also called "smallflower willowherb" in reference to its small size relatively. However that name, in particular the British English variant "small-flowered willowherb", typically refers to Epilobium parviflorum.
This annual wildflower is native to western North America from British Columbia and Alberta to California and Arizona. This is a plant of fields and meadows, including vernal pools, and it is one of the first flowers to spring up in areas recently cleared by wildfire.
Epilobium minutum is a small, spindly plant with thin, branching stems approaching a maximum of 40cm (20inches) in height. The sparse leaves are oval-shaped and 1cmor2cmcm (00inchesor01inchescm) long. The stems are topped with few tiny white to light purple flowers with notched petals each a few millimeters long. The fruit is a capsule 1cmor2cmcm (00inchesor01inchescm) in length. It is a much smaller plant than most members of the genus, referenced by both the specific name minutum as well as some of its common names.
