Cotoneaster horizontalis Decne. var. perpusillus Cotoneaster perpusillus Rockspray cotoneaster
Rock cotoneaster is native to western China, but has escaped and is now found in some areas of North America. Identification: These plants are prostrate, spreading horizontally over rock surfaces. They are 12-30" (30-76 cm) in height—the ones I have seen so far are plastered nearly flat against the rock. They may spread up to 8' (2.4 m). Stems may have a fishbone pattern. Leaves are alternate, unlobed, dark green on top, light green and finely hairy below, ⅛-¼" (6-8 mm) in length. Plants are semi-evergreen, retaining at least some leaves in winter; leaves become tinged with purple. Flowers are pale pink, appear from May to June. Berries are bright red, oval-shaped, ~³/₁₆" (5-6 mm) × ¹/₁₆-⅛" (3-4 mm), distributed evenly among the foliage. Online References:
