Clematis alpina
This early‑flowering species produces nodding, bell‑shaped flowers in spring. It is compact for a clematis and suits cooler summer regions. It performs well in sun to light shade with cool, moist, well‑drained soil. It needs only minimal pruning because it flowers on old wood. Provide light training on wires or a small trellis. Attractive seed heads extend interest after bloom.
