Guelder rose is native to Europe and Asia.
Identification: This shrub reaches 13-16' (4-5 m), with three-lobed, coarse-veined, somewhat maple-like leaves 1¾-4" (5-10 cm) in size. Leaves have course serrations, and occur in opposing pairs. Flowerheads (technically corymbs) are 1½-4" (4-11 cm) around. Each corymb has an outer ring of sterile, white- or cream-colored flowers ½-¾" (1.5-2 cm) around, with five petals. Within this ring is a large number of very small, fertile flowers, also white, about ⅛" (5 mm) around. The fruits are brilliant red when ripe, ⅛-¼" (3.2-6.3 mm) in diameter, round or somewhat oval.
