Nepal clematis · Clematis napaulensis
Best planted against a warm, sheltered, south-facing wall in moisture-retentive, well-drained soil with the crown 5-8cm (2-3in) deep to encourage new shoots to grow from below ground level. Choose site carefully as this clematis is summer dormant and will die down during the summer months. See clematis cultivation for more advice
