Agapanthus Blue Rinse

Supplied from division:

Agapanthus ‘Blue Rinse’ is a striking African Lily with rounded heads of rich blue, trumpet-shaped flowers held on tall, sturdy stems above neat, strap-like green foliage. Flowering through summer, it adds bold structure and a glamorous, architectural feel to borders and large patio pots. Agapanthus is also great for pollinators, and the flowers are excellent for cutting. Once established it’s drought tolerant, but it flowers best with sunshine and free-draining 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 thrives in borders or large pots and is ideal for patio containers, sunny borders and gravel gardens. Avoid cold, waterlogged ground in winter.

How to Plant:

• Depth: Plant with the crown about 5 cm below the soil surface (or just covered 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.

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 flowers best when slightly restricted, so it’s excellent in pots. For extra winter safety, keep container plants on pot feet and in a sheltered position so the compost never stays soggy.
