​Agapanthus Fireworks

Agapanthus ‘Fireworks’ is a real showstopper—an African Lily with spectacular, two-tone flower heads that look like they’ve been dipped in paint. The buds open to deep violet-blue at the base, fading to bright white at the tips, creating a striking “sparkler” effect on tall, sturdy stems. Flowering in mid to late summer, it adds strong, architectural height to borders and looks incredible in large patio pots. It’s also a favourite with pollinators, bringing plenty of summer buzz to the garden.

For best performance, give ‘Fireworks’ a warm, sunny position with excellent drainage—Agapanthus loves sunshine and sulks in soggy winter soil.

Planting Instructions

When to Plant:

Plant bare roots in spring once the risk of hard frost has passed. In milder areas, you can also plant in early autumn so roots can settle before winter.

Where to Plant:
Choose a warm, sunny, sheltered position with well-drained soil. Agapanthus is ideal for sunny borders, gravel gardens and especially large patio pots, where it often flowers brilliantly. Avoid cold, waterlogged ground in winter.

How to Plant:

• Depth: Plant with the crown about 5 cm below the soil surface (or just covered when planting in a pot).
• Spacing: Space 30–45 cm (12–18 inches) apart to allow room to clump up.
• Soil Prep: Improve heavy soils with grit for drainage. In pots, use a free-draining compost mix and ensure good drainage holes.

Watering:
Water well after planting. Keep evenly moist while establishing, then water only during prolonged dry spells. In pots, water regularly in summer, allowing excess to drain away.

Aftercare Tips:

• Feed in spring and summer to encourage flowering, especially in containers.
• Deadhead spent blooms to keep plants tidy and encourage more flowers.
• In colder areas, protect crowns in winter with a dry mulch or move pots to a sheltered spot.
• Divide congested clumps every 3–5 years (best in spring) to maintain vigour.

Top Tip:
Agapanthus ‘Fireworks’ is brilliant in pots. Keep containers on pot feet and in a sheltered spot over winter so compost never stays soggy—wet winter conditions are the biggest enemy.
