Perennials
Agapanthus campanulatus 'Bressingham Blue'
Bressingham Blue Lily of the Nile
Agapanthus campanulatus 'Bressingham Blue' is a perennial known for its clusters of trumpet-shaped, deep blue flowers that bloom from mid to late summer. The blossoms, arranged in large umbels, create a stunning contrast against the plant's dark green, strap-like foliage. The long-lasting flowers are highly attractive to pollinators, such as bees and butterflies, adding both color and movement to the garden.
Originating from South Africa, Agapanthus campanulatus is well-suited to warmer climates and thrives in areas with plenty of sunlight.

Design tip
Late flowers extend the season, so set it behind or beside plants that finish in midsummer. Because it is easy about light, use it to carry a planting from a sunny end of the bed into the shadier side.
Where to see it
