Agapanthus africanus (Large Plant)

Agapanthus are spectacular border plants, which look exotic, but are fully hardy in the UK, and will last for many years in the right position. The strap-like leaves create a robust, space-filling clump in the border, and play host to 80cm (31") stems topped with deep blue, trumpet-shaped blooms in late summer.

Agapanthus is evergreen and will excel in Mediterranean-style plantings. Plants will appreciate a sheltered corner, and can be grown in the border or patio containers. The late summer flower displays of the African Lily are a sight to behold. Height: 1m (39"). Spread: 50cm (19").
