About Epilobium torreyi (S.Watson) Hoch & P.H.Raven
Epilobium torreyi is a species of flowering plant that belongs to the evening primrose family. It is commonly known by two common names: Torrey's willowherb and brook spike-primrose. This species is native to western North America, ranging from British Columbia in the north to California in the south. It can grow in many different habitat types, and it is most often found growing in moist areas. Epilobium torreyi is a hairy annual herb. It produces a narrow, upright stem that often grows taller than half a meter, with narrow, lance-shaped leaves arranged along the stem. Its hairy, glandular inflorescence holds very small white or pink flowers. These flowers are typically cleistogamous, meaning they remain closed and reproduce via self-pollination. The fruit produced by this plant is a capsule that reaches up to roughly one centimeter in length.
