Stanleya viridiflora is a species of flowering plant in the mustard family known as green princesplume and green-flowered princes plume. It is native to the western United States, where it occurs in sagebrush and plateau habitat, often on rocky calcareous, sandstone, clay, shale, or volcanic soils.

This is a perennial herb producing thick, erect stem which can exceed a meter in maximum height. It is hairless and sometimes waxy in texture. Its base is a caudex, which is usually covered with remnants of dead leaf bases. The leaves are lance-shaped or oblong blades that have smooth or toothed edges and can be divided into several blades. The blades can be 22 inches in length. Some of them are on long petioles, while others, especially those higher on the plant, clasp the stem at their bases. On top of the stem is a long inflorescence which is an open inflorescence of many flowers. Each flower Bud is enclosed in a long, thick sepals that open to reveal yellow or whitish petals up to 2 centimeters in length. The stamens protrude from the center of the flowers 1 or 2 centimeters long. The fruit is a curved, worm-like silique 4 to 7 centimeters long containing tiny seeds.
