Agapanthus Finn

Agapanthus Finn is a compact, deciduous variety featuring pure white, trumpet-shaped flowers held on sturdy stems during summer. Its neat, clumping foliage of narrow green leaves provides a tidy, structured appearance, making it an excellent choice for borders, edging, or container planting. The striking blue flowers bring vibrant colour to any garden space.

Well-suited to cottage, modern, or coastal gardens, Finn thrives in full sun and prefers well-drained soils. It is hardy, low maintenance, and moderately drought-tolerant once established. Space plants 20–30 cm apart for a dense and uniform display.

Mature size: Grows up to 40–50 cm in height and width, forming a compact, clumping habit.

Trimming: Cut back foliage in late autumn or winter once it has died back naturally. Remove any yellowing or damaged leaves during the growing season to maintain a tidy appearance.

Deadheading: Remove spent flower stems after flowering to encourage further blooms and prevent self-seeding, especially if managing invasive tendencies.

Fertilising: Feed with a balanced, slow-release fertiliser in spring to promote healthy growth and flowering. Avoid over-fertilising, as this can reduce flower production.

Watering: Water regularly during the establishment phase and dry periods. Established Agapanthus are drought-tolerant but will benefit from occasional deep watering during hot weather.

Pest Control: Check for slugs, snails, and mealybugs. Remove pests manually or use suitable deterrents.

Disease Management: Agapanthus are generally disease-resistant but may develop root rot in poorly draining soil. Ensure soil is well-draining and avoid overwatering.
