Canyonlands biscuitroot is a threatened, tiny perennial desert herb of the carrot family, found only on the Utah-Colorado border in sandstone crevices. It is not a commonly grown garden plant, and the key to any cultivation is to mimic its harsh, well-drained native sandstone habitat and leave wild populations undisturbed.
