How to grow

Cultivation

In colder areas, grow in containers in peat-free, loam-based compost, water freely when in growth but sparingly in winter, and apply a balanced liquid fertilizer monthly from spring until flowering; in milder areas, grow outside in moisture-retentive but well-drained soil in full sun, in a sheltered position such as a south-facing or wet-facing wall, and provide winter protection with a dry mulch; for more advice, see Agapanthus cultivation

Propagation

Propagate by division in spring

Pruning

No pruning required except cutting back dead flower stems, but allow them to remain until spring, because the seedheads look attractive over winter
