Agapanthus are strikingly exotic-looking border perennials, yet fully hardy in the UK and will last for many years in the right spot. The evergreen, linear leaves create a space-filling clump in the border and are topped with 80cm (31) stems and deep blue, umbel shaped flowers from late summer. Perfect in Mediterranean-style plantings, these perennials will enjoy a sheltered corner, growing in a border or patio pot where the blooms will create an eye-catching display. Height: 1m (39). Spread: 50cm (19).
