Description
Yellow Clematis is a perennial vine; producing several stems per plant that can grow up to 4 m in length. Young stems are pliable while the older stems can become very woody. Leaves are green and compound with 5-7 lance-shaped leaflets 5-6 cm long, which may be lobed. Leaf tips are pointed and leaf edges are coarsely toothed. Leaves may be slightly hairy on the underside and are deciduous. Flowers are lemon-yellow, nodding, with four petals. Flowers are bell-shaped at first and then split as the petals spread. Petals may be silky-hairy on the outside and occasionally tinged purplish-brown. Flowers are borne at the ends of stems or in leaf axils, usually solitary but sometimes 2 or 3 together, on a short (0.5-3 cm) flower stem. Seeds are oval to 4.5 mm long, with silky tails about 5 cm long.
