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

Atragene Group consists of woody climbers with deciduous, 1 to 2-ternate leaves and nodding, bell-shaped, single or double flowers to 10cm across, on old wood in spring and early summer, occasionally also later, on current year's growth

'Francis Rivis' is a medium-sized deciduous climber with narrow, serrate leaflets. Flowers with four tapering, clear light violet-blue sepals 5cm in length, surrounding prominent cream staminodes and stamens in early to late spring with occasional flowers in late summer.
