Agapanthus Seafoam is a striking evergreen variety known for its unique pale white flowers, often tinged with soft green at the base, which appear on tall stems during summer. Its strap-like green foliage forms a tidy, clumping habit, providing year-round interest. The subtle, frothy colouring of the flowers lends a soft, airy quality to any planting scheme.
Perfect for coastal, cottage, or modern gardens, Seafoam thrives in full sun and well-drained soils. It is low maintenance and drought-tolerant once established, making it ideal for borders, mass plantings, or as a statement in large containers. Space plants 40–50 cm apart for a balanced, natural spread.
Mature size: Reaches up to 60–80 cm in height (including flower stems) and 40–60 cm in width, forming a lush, clumping habit.
Trimming: Cut back spent flower stems after flowering to maintain a neat appearance. Remove any dead or damaged leaves to promote healthy growth.
Deadheading: Regularly deadhead wilted flowers to encourage prolonged flowering and prevent self-seeding.
Fertilising: Apply a balanced fertiliser in spring and again in mid-summer. Avoid high-nitrogen fertilisers as they can lead to excessive leaf growth at the expense of flowers.
Watering: Water well during the establishment phase and keep the soil consistently moist but well-drained. In periods of drought, water deeply once a week.
Pest Control: Be vigilant for snails and slugs, particularly in the spring. Use organic slug pellets or copper tape to protect the plants.
Disease Management: Agapanthus Seafoam is generally resistant to diseases but can suffer from root rot if overwatered. Ensure good drainage to prevent this. Yellowing leaves with brown spots may indicate a fungal infection; treat with an appropriate fungicide if necessary.
