Leaves are typically elongated and sword or oval shaped. Flower clusters grow on the same branches as leaves. Flower buds go from green to yellow as they mature, and flowers have four bright yellow petals. Yellowcress fruit is dry, curves upward, and contains many seeds. Seeds are usually angled and plump.
