About

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.
