Agapanthus Blue Giant

(inc. 20.0% VAT)


Out of stock


Agapanthus ‘Blue Giant’ is a handsome, towering Agapanthus, with stems of spectacular blooms up to 1m in height. 

Exotic umbels of azure-blue, trumpet-shaped flowers are borne in large clusters, forming globes of bold colour – ideal for adding architecture, shape and interest to borders and containers.

Strong purple stems rise up from a bed of dark green, strap-like foliage in late summer, before bursting into bloom during August and September.

Native to South Africa, Agapanthus suit modern and traditional planting schemes, they thrive in coastal regions and look fabulous in oversized terracotta pots.

Care Guide

Elegant Agapanthus are best grown in large terracotta pots or containers, in a sunny spot. Fill containers with loam-based soil, enriched with organic matter. Plant rhizomes 20cm deep and 15cm apart, ensuring they rest 5cm below the surface. Maintain soil moisture with regular watering, never allowing soil to become waterlogged. Sturdy stems of spectacular white or blue umbels will reach heights of 60-90cm in late summer. Only re-pot if the plants are pot bound. Half-hardy Agapanthus require crown protection during winter with a thick layer of straw or mulch. In colder regions, containers should be brought undercover for the winter months.
