Rockspray, cotoneaster Horizontalis, is a prostrate, slow-growing, horizontally-spreading,
deciduous shrub, which typically matures to 12-18" tall and spreads to 5-8' wide
with tiers of flattened, horizontal branches arranged in a fishbone pattern.
It features five-petaled, small pink flowers in early summer,
bright scarlet berries in late summer to autumn
and tiny, rounded, lustrous, dark green leaves (to 3/8" long) that turn reddish-purple in autumn.
