Clarkia unguiculata is a species of wildflower known by the common name elegant clarkia or mountain garland. This plant is endemic to California, where it is found in many woodland habitats. Specifically it is common on the forest floor of many oak woodlands, along with typical understory wildflowers that include Calochortus luteus, Cynoglossum grande and Delphinium variegatum. C. unguiculata presents a spindly, hairless, waxy stem not exceeding a meter in height and bears occasional narrow leaves. The showy flowers have hairy, fused sepals forming a cup beneath the corolla, and four petals each one to 2.5 centimeters long.

The stigma protrudes from the flower and can be quite large. Flowers of the genus Clarkia are primarily pollinated by specialist bees found in their native habitat "Clarkias independently developed self-pollination in 12 lineages."
