Silene noctiflora

The night-flowering catchfly is an annual herb producing a hairy, glandular stem up to about 75 or 80 centimeters in maximum height. It is sticky in texture. The hairy, widely lance-shaped leaves grow in opposite pairs and are up to 14 centimeters long and 5 wide, the largest ones located low on the stem. The flowers are nocturnal, and occur in an open cyme of up to fifteen blooms, each borne on an erect pedicel. The flower is encapsulated in a hairy calyx of fused sepals lined with a netlike pattern of veining. The five petals are white to pink and each has two lobes at the tip. They measure up to 2.5 centimeters wide when fully open. The fruit is a yellowish-brown capsule with six chambers which splits open to release the seeds.
