Salvia Marvel Blue 2ltr

Salvia ‘Marvel Blue’ is a brilliant choice if you want big, bold colour and a long season of flowers. It produces eye-catching large, deep blue blooms held in generous clusters above fresh green foliage, creating a lush, vibrant look from summer well into autumn. It’s a fantastic plant for adding punch to sunny borders and patio pots, and it’s also a favourite with bees and other pollinators, bringing extra life and movement to your garden.

Despite the showy flowers, it’s wonderfully easy to grow: give it warmth, sun and good drainage, and it will reward you with months of colour—especially if you give it a quick tidy after each flush.

Planting Instructions

When to Plant:

Plant in spring or early autumn, while the soil is workable (avoid planting into frozen or waterlogged ground).

Where to Plant:
Choose a sunny, sheltered position with well-drained soil. Salvias dislike winter wet, so drainage is key. Ideal for mixed borders, gravel gardens, raised beds, and pots and containers.

How to Plant:

• Depth: Plant so the top of the compost is level with the soil surface.
• Spacing: Space plants 35–45 cm (14–18 inches) apart to allow a bushy shape.
• Soil Prep: If your soil is heavy, mix in horticultural grit to improve drainage. Avoid over-fertile soil which can encourage softer growth.

Watering:
Water well after planting and keep watering while the plant establishes. Once established, salvias are fairly drought tolerant, but they will flower best with occasional watering during prolonged dry spells (especially in pots).

Aftercare Tips:

• Deadhead or lightly trim after each flush of flowers to encourage more blooms.
• In spring, cut back to healthy growth to keep plants compact and floriferous.
• In colder or very exposed gardens, provide winter protection (a dry mulch around the base, or move pots to a sheltered spot).

Top Tip:
Salvia ‘Marvel Blue’ looks stunning with whites, pinks and silvery foliage. For the longest show, give it a quick trim after a big flowering burst and it will often bloom again.
