is found only in high elevation regions of California's Sierra Nevada, above 10,000 feet, on talus slopes, at the base of cliffs and along lakesides. The finely-divided leaves are very small, reduced in size to conserve water, and grow along spike-like stems around 6 inches long. Flower stalks are a little taller, topped by spherical clusters of several dozen lavender flowers. Flower heads consist of a five-lobed corolla with a narrow, tubular center, colored deeper purple. Blooms emit a pungent odor to maximise the chance of pollination during the short summer growing season. Flowers are fully open only for a few days.
