Description
Evening Primrose is a North American native biennial plant. The plants are very tall, often 4 to 5 feet or more in height. The stem is erect, stout, soft-hairy, reddish and branching forming a shrub. Leaves are alternate, rough-hairy, lanceolate, about 3 to 6 inches long and lemon-scented. The taproot is elongated, fibrous, yellow on the outside and whitish within. The flower spikes grow on auxiliary branches all along the stalk. They are about 2-1/2 inched in diameter, bright yellow and have four petals, a cross shaped stigma and a refluxed calyx (leaves under petals). The flowers open in the evening and close up during the day and are strongly scented with a delicious sweet perfume which attracts pollinating moths. The fruit is an oblong 1 in. capsule containing many tiny reddish seeds.
Habitat
Evening Primrose is found east of the Rockies to the Atlantic. Naturalized in Britain but found all over the world. It grows by roadsides, railway banks and waste places in dry open soils, gravelly places, meadows and old fields.
