Description This subtropical shrub graces hillsides in Southern Arizona with its abundance of yellow, bell-shaped flowers. Yellow bells thrives at the transition zone between grasslands and desert scrub. Generally found above drainages near large rocks where reflected heat keeps the plants from freezing too hard in the wintertime. Local plants are considered to be variety angustata which has narrow leaflets and more tolerance to cold than more tropical varieties.
