Shasta rockcress, Shasta Rockcress

Family: Brassicaceae · Type: perennial · Native

Shasta rockcress is a California native perennial found in eastern Klamath Ranges, northern California Interior Ranges, California Roaring Fork, northern Sierra Nevada Foothills, and Sutter Buttes in rocky woodland areas at elevations of 300 to 1,200 meters. Flowering from March to June, this plant produces small white to pale lavender flowers on delicate stems. Growing 18 to 45 centimeters tall with slender, erect stems that are sparsely hairy or glabrous, it forms an upright, narrow habit characteristic of rockcress species. Its leaves are generally narrow and elongated, arranged alternately along the stem, with smooth or slightly toothed margins. The fruit develops on pedicels longer than 9 millimeters, creating distinctive elongated seed pods typical of mustard family plants.
