Care notes
- 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 a 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 deadheading, but allow dead flower stems 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
- May be susceptible to slugs and snails and agapanthus gall midge but generally pest-free
- Disease resistance
- May be susceptible to a virus
