Clematis can be deciduous or evergreen shrubs or herbaceous perennials, mostly climbing by twining leaf-stalks, and often with showy flowers. Some have attractive fluffy seed-heads in autumn

Velvety, bell-shaped pale yellow flowers 2cm in length with reflexed tips and greenish-brown stamens are borne in 9cm long panicles, and are sweetly scented. Flowers midsummer to early autumn
