Agapanthus 'Glenavon' (Large Plant)

African Blue Lily

A particularly pretty African Blue Lily that deserves a prominent spot in your garden. Agapanthus 'Glenavon' produces dense, rounded umbels of pale blue flowers with a violet stripe along each petal. The sturdy stems each rise to 1m (3') above clumps of linear, semi evergreen foliage that makes useful groundcover. This hardy perennial is tough and reliable, coping well in most soils and at its best in a sunny position. Plant it in large clumps toward the middle of borders for a superb impact from July to September. Height: 100cm (39"). Spread: 50cm (20").
