is a low growing, branched, shrub-like species that can form large clumps. Plants are quite colorful; bright green leaves (paler underneath), reddish stems and light pink flowers. Stems contain milky sap. Leaves have distinct, lighter-colored veins, and rounded tips. They are angled outwards or downwards, rather than upwards. Leaf length is around twice the width.
Flowers grow from the tip of the stems and the upper leaf nodes; they have a bell-shaped corolla that opens to five small lobes. Stamens and stigma are short, generally hidden at the base of the corolla tube. Beneath the flower are five pinkish green sepals (fused at the base), often bent back away from the corolla. The calyx is much shorter than the corolla - unlike the similar apocynum cannabinum
. Each flower produces a pair of cylindrical fruits.
