Care notes
- Cultivation
- In milder areas, grow outside in full sun, in a sheltered position such as a south-facing or west-facing wall, in moisture-retentive but well-drained soil, and provide winter protection with a loose mulch; 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; for more advice, see Agapanthus cultivation
- Pruning
- No pruning required except cutting back dead flower stems, but allow them to remain until spring, because the seedheads look attractive over winter
- Propagation
- Propagate by division between spring and early summer, or in early autumn after plants have finished flowering
- Pest resistance
