Description
Clarkia springvillensis is an annual herb growing erect to approach a maximum height near 1 metre (3.3 ft). The lance-shaped leaves are up to 9 centimeters long. The herbage is hairless and waxy in texture.
The inflorescence bears open flowers and hanging, closed flower buds. The deep red sepals remain fused together as the petals bloom from one side. Each petal is a diamond-shaped blade at the end of a long claw. It is pinkish-lavender with a purple spot at the base. There are 8 stamens, some with large, red anthers and some with smaller, paler anthers. The stigma protrudes from the center.
