Product Description

Agapanthus Blue (1 Bulb)

Agapanthus 'Blue' Bulb Agapanthus Blue, also known as the African Lily, is a stunning perennial that brings a touch of Mediterranean charm to any garden. Known for its tall, elegant stems topped with clusters of vivid blue flowers, this Agapanthus variety adds height, colour, and structure to borders, beds, and containers. Blooming from mid-summer to early autumn, Agapanthus Blue is easy to grow and thrives in sunny spots, making it a fantastic choice for UK gardens. Its striking blue blooms are also perfect for cut flower arrangements, bringing a splash of colour indoors.
The blooms of Agapanthus Blue are a rich, deep blue, with clusters of trumpet-shaped flowers forming rounded heads that sit atop slender stems reaching heights of up to 90cm. Each flower head contains dozens of delicate blue blooms, creating a dramatic and eye-catching display that attracts bees and other pollinators. The lush green, strap-like leaves at the base add texture and contrast to the garden, providing a beautiful backdrop for the vivid blue flowers.
How to Grow
Planting: Plant Agapanthus bulbs in spring or autumn. Choose a sunny, sheltered location with well-drained soil, as Agapanthus thrives in full sun and prefers light, fertile soil. Plant the bulbs around 5-10cm deep and space them about 20-30cm apart. For container planting, use a loam-based compost with added grit for drainage.
Watering: Water the bulbs well after planting to help them establish. During the growing season, keep the soil consistently moist, especially in hot, dry weather. However, avoid waterlogging as Agapanthus prefers well-drained conditions.
Feeding: Feed Agapanthus with a balanced liquid fertiliser every two weeks during the growing season, starting in spring and continuing until the blooms fade. This will encourage healthy growth and abundant flowering.
Staking: In windy areas, taller Agapanthus plants may benefit from light staking to keep the stems upright and prevent damage, especially when they are in full bloom.
Deadheading and Maintenance: Remove spent flower heads to encourage a tidier appearance and to redirect energy back to the bulb. Allow the foliage to die back naturally after flowering, as this helps the plant store energy for the next season.
Overwintering: Agapanthus is generally hardy in the UK, but in colder areas, protect the plants in winter by adding a layer of mulch around the base. For container-grown Agapanthus, move pots to a frost-free location or cover them to prevent freezing.
With its tall, elegant stems and vibrant blue flowers, Agapanthus Blue brings a touch of exotic beauty to gardens, creating a spectacular display from summer through early autumn. Easy to care for and perfect for both borders and containers, this plant adds a striking focal point and is an ideal choice for cut flowers, bringing garden charm indoors.

FAQs

Please read our FAQs page to find out more.

Why has my agapanthus not flowered?

Agapanthus need plenty of sun to flower well, so a shaded position is one of the most common causes of leafy plants with no blooms. Young plants and recently divided clumps can also take time to settle before flowering strongly. Keep the soil moist during active growth but free-draining, and protect the crown from severe winter cold. In pots, avoid moving agapanthus into a much larger container too soon, as they often flower better when their roots are reasonably contained.

Can agapanthus survive winter in the UK?

Many deciduous agapanthus are hardy in the UK and lose their leaves naturally over winter. Evergreen agapanthus are more tender and need protection from frost, particularly in colder areas. Mulch plants growing in the ground and move container-grown plants to a frost-free greenhouse, conservatory or sheltered position for winter. Cold and wet conditions around the roots are more damaging than cold alone, so ensure pots and borders drain well.

Can I grow agapanthus in pots and containers?

Yes. Agapanthus grow very well in large pots and containers, making them ideal for patios and sunny spaces. Use a container with drainage holes and place it in full sun. Water regularly during spring and summer, as containers dry out more quickly than borders, and feed during active growth to support strong flower stems. Protect potted agapanthus over winter, as roots in containers are more exposed to frost than plants growing in the ground.

Why are my agapanthus leaves turning yellow or brown?

Yellowing or browning leaves can be caused by winter cold, drought, waterlogged soil or natural seasonal die-back in deciduous types. Check that the soil is not staying wet for long periods and that potted plants have clear drainage holes. Water agapanthus during dry spells in summer, especially when growing in containers. Remove leaves only once they have fully died back, as healthy foliage helps the plant store energy for future flowers.

Do agapanthus spread, and when should I divide them?

Agapanthus gradually form larger clumps from their fleshy roots. They do not usually spread aggressively, but crowded plants may produce fewer flowers over time. Divide established agapanthus every 3 to 4 years in spring, separating healthy rooted sections and replanting them into fertile, free-draining soil or fresh compost. Newly divided plants may take a little time to settle before flowering at their best again.
