About Agapanthus
Agapanthus praecox is a fast-growing perennial in the Amaryllidaceae family. It reaches around 80 cm tall at maturity, with evergreen foliage. Blue and white flowers appear in summer.
Where to grow Agapanthus
Agapanthus suits warm-temperate, Mediterranean and subtropical climates and grows best in full sun and part shade or morning sun. It is frost hardy and shrugs off cold winters. It also tolerates salt-laden coastal winds and is a genuinely water-wise choice.
Soil & planting
Most soils suit Agapanthus provided drainage is reasonable. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Agapanthus is very drought tolerant once established, so once its roots are down it needs little supplementary water. A feed in spring with a balanced fertiliser keeps growth strong. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Prune Agapanthus after flowering to keep it compact and encourage the next flush of blooms. Overall it is low maintenance.
Using Agapanthus in the garden
Agapanthus earns its place for a feature or specimen planting, pots and courtyard containers and holding soil on banks and slopes. It is equally at home in the ground or a large pot on a balcony or courtyard.
Companion planting & design
For a cohesive, low-care bed, pair Agapanthus with other plants that enjoy the same very drought tolerant and warm-temperate climate. Group three or five together for impact rather than dotting single plants through the garden.
Good to know
Be aware it can self-seed or spread into bushland in some regions — check it is not a declared weed in your area before planting.
