Primula suffrutescens is a species of primrose known by the common name Sierra primrose.
Primula suffrutescens is a subshrub growing from a sturdy anchoring rhizome. It has a matlike form with a thick, woody base covered in the dried remnants of previous seasons' herbage. The green leaves occur in several rosettes on the woody base. The hairless leaves are spoon-shaped with jagged, toothed tips and measure up to 3.5 centimeters long.
From the rosettes arise inflorescences on peduncles up to 12 centimeters tall. The showy inflorescence is an umbel of several flowers with tubular yellow throats and flat magenta corollas with five jagged or notch-tipped lobes. The fruit is a capsule.
