How to grow
Cultivation
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 mild areas, grow outside in moisture-retentive but well-drained soil in full sun, and provide winter protection with a dry mulch; for more advice, see Agapanthus cultivation
Propagation
Propagate by division between spring and early summer, or in early autumn after plants have finished flowering
