How to grow
Cultivation
Grow in moisture-retentive but well-drained soil in full sun, and in colder areas provide winter protection with a dry mulch; in containers, grow in loam-based compost such as John Innes No. 3, 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
Propagation
Propagate by division between spring and early summer, or in early autumn after plants have finished flowering
