Leaves: Mostly basal leaves from a rosette, 3/4 to 3 inches long, narrow, oblanceolate, pointed tip, fleshy. Inflorescence: Several small, erect blossoms in a raceme, each with 4 white to pale lavender petals. Bloom Period: May to August. Fruit: Capsules are smooth, very narrow, linear, 1-1/2 to 4 inches long and about 1/8-wide or less; erect, usually appressed to the center stalk of the inflorescence. Reference: "Guide to Colorado Wildflowers" by G.K. Guennel, "Flora of Colorado" by Jennifer Ackerfield and SEINet. Note: In early spring, some plants become infected with Puccinia monoica, a rust fungus that stops the rock cress from flowering and forces it to form the brilliant yellow pseudoflowers containing the reproductive structures of the rust fungus.
