In the garden

Clematis douglasii belongs to the Ranunculaceae and is a compact climbing vine native to western North America. In cultivation it typically grows to around 0.6 m and carries its flowers through the summer months, May to September. Plant where it receives full sun and in soil that remains moist but well drained; it will tolerate sandy, loamy or clay soils. The species is rated H7 for the UK (fully hardy) and corresponds to USDA zones 5–9, so it survives normal outdoor winters without need for winter protection. Given its modest height, provide a low support or allow it to scramble among low-growing shrubs. Clematis douglasii suits wildlife gardens, naturalised areas and slopes where a lower-growing climber is required. Its summer flowering period makes it useful where extended bloom is wanted through the warmer months. Flowering runs May to September and its compact 0.6 m growth makes it particularly apt for low trellis, bank planting and wildlife margins.
