Clematis flammula aka Fragrant Clematis

Clematis flammula is a deciduous climber in the buttercup family, Ranunculaceae. Its common names include sweet-scented virgin's bower and virgin's bower. Its native range stretches from the Mediterranean region to Pakistan. It grows in hedges, thickets, and waste ground. It is not native to Britain or Ireland. This species suits temperate gardens and loses its leaves in winter.

This vigorous vine reaches 8–13 feet [2.5–4 metres] in gardens. Its spread is about 3–5 feet [1–1.5 metres]. It takes about two to five years to reach full size. The leaves are glossy and deep green, with separate leaflets. Small white flowers form large panicles in late summer and autumn. Each flower is single, and the blooms have a sweet scent. The flowers appear in large numbers, followed by fluffy seed heads. These add interest after the main flower display ends.

Choose a sheltered spot in full sun for garden planting. The plant accepts chalk, clay, loam, and sandy soils. It also tolerates acid, neutral, and alkaline conditions. Soil should hold moisture but let excess water drain away. Keep the roots and stem base cool and shaded. Nearby plants or a layer of pebbles can provide shade. Set the crown 2–3 inches [5–8 centimetres] below the soil surface. This helps new shoots grow from below ground. The RHS rates it H5 for UK hardiness. Plants For A Future lists USDA zones 5–9.

This climber suits wall-side beds, courtyards, and informal gardens. The RHS also lists patios, containers, and flower borders as uses. It can scramble across the soil as ground cover. For this use, plant about 4 feet [1.2 metres] apart. Its scent adds another reason to grow it near garden spaces. The RHS places it in pruning group three. Grow new plants from ripe seed, cuttings, or layers. Softwood cuttings suit spring, while semi-ripe cuttings suit early summer. Layer stems in late winter or early spring.

Watch for aphids, snails, and caterpillars; earwigs may chew the petals. Clematis wilt and slime flux can also affect this species. Honey fungus is a less frequent risk. All parts are poisonous, and contact can irritate skin. Wear gloves and protective clothing when handling the plant. It is also harmful to rabbits if eaten. Plants For A Future records cooked young shoots as a food use. That source also warns of toxicity, so this is not a safe grazing plant.
