Clematis viticella is the accepted purple or Italian clematis species in Ranunculaceae, native to southern Europe and western Asia. It is a vigorous, rapid, deciduous perennial climber with mid-green leaves composed of two or three lobed leaflets. Current-season stems carry single open bell-shaped flowers in summer and early autumn, each directly documented by RHS at 4 cm across, with four broad purple or violet-blue tepals and creamy-yellow anthers. Structured dimensions follow the direct RHS range of 250-400 cm high and 100-150 cm wide. North Carolina Extension lists USDA subzones 4a through 8b, normalized without widening to zones 4-8. Grow in fertile, moisture-retentive but well-drained neutral to alkaline soil in full sun or partial shade, keeping the roots cool and shaded. Plant the root ball 5-8 cm below the soil surface and provide a graspable support. Use on arbors, fences, walls, patios, containers, cottage borders, naturalized areas or woodland edges. Propagate by softwood or semi-ripe cuttings or layering. Prune hard as Group 3 in late winter or early spring. Slugs, snails, voles and aphids may attack; honey fungus, clematis wilt, slime flux and powdery mildew can occur. All parts are toxic if eaten and sap can irritate skin. Small dry achenes have silky feathery tails, but no direct exact scalar fruit dimensions were found, so all fruit measurements remain blank.
