Barneby's pepperwort is a critically rare Utah endemic that requires very specific semi-shaded, moist conditions to thrive. It is not suited to general home gardens and is best left to specialist native plant enthusiasts or conservationists. Avoid disturbing the root zone and replicate its natural riparian habitat as closely as possible.
