Durand's clematis · Clematis × durandii
Plant in a moisture-retentive, well-drained soil. Keep the base of the plant and roots cool and shaded by other plants. Plant with the crown of the clematis at soil level. Mulch in late winter with garden compost or well-rotted manure, avoiding the immediate crown. Ideal for a border where it can scramble, be supported by other plants or by staking.
