Oenothera filiformis is an herbaceous perennial plant with an erect, unbranched stem that may grow as high as five feet. The species can be dioecious or females can have erect spikes of motile spores. All parts of the plant are pubescent, meaning with fine hair covering them.Leaf: The basal leaf rosette can be the first year’s growth or beginning of the year’s growth. It may or may not be present when the plant blooms. The stem leaves are alternate with a short, winged petiole. Small leaves can grow at the base of the petiole. Each leaf is long flaring out to the middle then tapering to a point. The wavy edges are irregular but not lobed or toothed. There is a single midvein. Top and bottom of the leaf is green, slick-looking and covered with short hairs.
They are annual, biennial or perennial herbaceous plants; most are perennials with sturdy rhizomes, often forming dense thickets, crowding or shading out other plant species. They have a basal rosette of leaves, with erect or spreading flowering stems up to 2 m (rarely more) tall, leafy on the lower stem, branched and leafless on the upper stem. The flowers have four (rarely three) petals; they are zygomorphic, with all the petals directed somewhat upwards. The fruit is an indehiscent nut-like body containing reddish-brown seeds. It reproduces via seeds and also by rhizome growth.
