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

C. x aromatica is a non-clinging, woody-based herbaceous perennial to 2m tall, with divided leaves and large sprays of scented, small, single, deep violet flowers 4cm across with contrasting white stamens, the petals with edges rolled under as the flower matures, from early summer to mid autumn
