Agapanthus africanus 'Albus' – Planting & Care Guide

About Agapanthus africanus 'Albus'

Agapanthus africanus 'Albus', commonly known as the White African Lily or Lily of the Nile, is a striking evergreen perennial admired for its large, rounded clusters of pure white trumpet-shaped flowers held high above elegant, strap-like green foliage. Flowering from mid to late summer, it brings a sophisticated touch to borders, containers and coastal gardens.

Growing to approximately 60–90cm tall with a spread of 45–60cm, 'Albus' forms neat clumps that become more impressive each year. Its architectural form makes it a standout feature in both traditional and contemporary gardens, while its nectar-rich flowers attract bees, butterflies and other beneficial pollinators. It is particularly well suited to Ireland's mild climate when planted in a sunny, well-drained position.

Planting Guide

• Plant in full sun for the best flowering performance.
• Choose a warm, sheltered position protected from cold winds.
• Prefers fertile, well-drained soil.
• Improve heavy soils with compost and horticultural grit before planting.
• Dig a planting hole twice the width of the root ball and the same depth.
• Plant with the crown sitting level with the surrounding soil surface.
• Firm the soil gently around the roots and water thoroughly after planting.
• Apply a light mulch around the base, keeping it clear of the crown.
• Space plants approximately 45–60cm apart.
• Agapanthus flowers best when its roots become slightly congested, making it an excellent choice for containers.

Care & Maintenance

Agapanthus 'Albus' is a reliable, low-maintenance perennial once established.

• Water regularly during the first growing season.
• Once established, water during prolonged dry periods.
• Avoid waterlogged soil, particularly during winter.
• Feed in spring with a balanced slow-release fertiliser.
• Apply a high-potash fertiliser every two to three weeks during the flowering season to encourage abundant blooms.
• Remove weeds regularly from around the base.
• Refresh mulch annually to conserve moisture and improve soil quality.
• Water container-grown plants more frequently during warm weather.
• Protect young plants with mulch during severe winters in colder areas.

Pruning

Very little pruning is required.

• Remove faded flower stems once blooming has finished.
• Cut away any damaged or yellowing leaves as required.
• Remove dead foliage in early spring before new growth appears.
• Divide overcrowded clumps every 4–5 years in spring if flowering declines.
• Avoid dividing too frequently, as slightly crowded roots encourage better flowering.
