Agapanthus Brilliant Blue – Evergreen African Lily
Agapanthus Brilliant Blue is a striking evergreen African Lily renowned for its exceptionally rich deep blue flowers and compact, free-flowering habit. Large rounded flower heads are packed with vibrant trumpet-shaped blooms, each enhanced by a darker central stripe that adds depth and intensity to the display. The flowers are carried on sturdy upright stems above neat clumps of evergreen strap-like foliage, creating a spectacular show throughout the summer months.
Growing to approximately 60–75cm in height, Agapanthus Brilliant Blue is an excellent choice for borders, patio containers and smaller gardens. Its compact habit allows it to fit easily into a wide range of planting schemes while still producing an abundance of flowers. Furthermore, the nectar-rich blooms attract bees and other pollinating insects, helping to support garden wildlife throughout the flowering season. The evergreen foliage also provides valuable structure and interest throughout the year.

Growing Agapanthus Brilliant Blue
Agapanthus Brilliant Blue thrives in a sunny, sheltered position with fertile, well-drained soil. Full sun encourages abundant flowering and helps develop the richest flower colour. Additionally, plants perform exceptionally well in containers where slight root restriction often encourages even more prolific flowering. Once established, this variety is relatively drought tolerant and requires only occasional watering during prolonged dry periods.
As an evergreen variety, the attractive foliage remains an important feature throughout the year. Remove spent flower stems after flowering to maintain a tidy appearance. Furthermore, tidy any damaged or weathered leaves in spring to encourage fresh growth. In colder regions, provide winter protection during severe frosts, particularly for container-grown plants, to ensure healthy foliage and reliable flowering year after year.
