Cotoneaster horizontalis - Rockspray Cotoneaster

The Rockspray Cotoneaster can almost be considered a groundcover, and I often use it in designs to produce the effect of ground-covering undulations, as the plant's center grows up from the ground until the branches get too heavy and droop to the ground, where they will spread up to a few feet, meeting the next plant. This produces a wonderful visual effect like you might see in some Japanese gardens using junipers for the same purpose. The plant blooms in mid to late May, with dark pink buds that open to very light pink flowers. Foliage is a very glossy dark green with a fine hair or fuzz on it. New woody growth is green, turning to brown as it matures. This is a very densely foliated plant that can serve well in a rock garden as a contrast to the simple look of larger stones.
