Agapanthus africanus is a clump-forming, semi-evergreen perennial bulb with strappy, mid-green leaves and balls of deep blue, funnel-shaped flowers held singly on upright stalks that resemble azure fireworks exploding throughout late summer. Although not the hardiest African lily it is arguably one of the best in colour and form. Plant shallowly in full sun and keep undisturbed for best results, mulching with gravel if possible to keep the crown free of moisture and avoiding rot. Alternatively grow in a pot and bring under cover during winter
