Plant information

Plant Description

Salvia ‘Blue Merced’ is a striking perennial salvia that fills borders, containers, and garden beds with vivid blue flowers throughout the summer months. Its long flowering season, from early summer into autumn, ensures continuous colour and movement, making it a standout choice for sunny planting schemes.

The rich, nectar-filled blooms are a magnet for bees, butterflies, and other pollinators, adding life and energy to your garden. The aromatic green foliage complements the vibrant blue flowers, creating a beautiful contrast and adding a subtle fragrance when brushed.

With a tidy, bushy habit, ‘Blue Merced’ works beautifully in mixed borders or as a feature in patio containers, providing structure without overwhelming neighbouring plants. Thriving in full sun with well-drained soil, it is drought-tolerant once established and requires very little maintenance. A light trim after flowering encourages a second flush of blooms, extending the season of colour.

Hardy in most parts of the UK, it may need protection in colder areas during severe frost. For gardeners seeking long-lasting colour, pollinator appeal, and easy-care performance, Salvia ‘Blue Merced’ is an elegant, reliable addition that brightens any outdoor space. This variety was introduced to the market in 2019.

🌿 How to Care for Salvia ‘Blue Merced’

How do I prune Salvia ‘Blue Merced’?
Salvia ‘Blue Merced’ should be left through the winter, as the dead wood protects them from frost. They can be pruned in early spring, and more vigorous varieties may be trimmed again around June.
Salvia ‘Blue Merced’ can be susceptible to aphids, capsid bugs, whitefly, sage leafhoppers, and glasshouse red spider mites. Additionally, fungal issues like grey mould (Botrytis) can develop in cool and damp conditions, especially during overwintering.
Water Salvia ‘Blue Merced’ regularly during dry spells, particularly newly planted ones. Established hardy salvias are drought-tolerant but benefit from deep watering during prolonged hot periods. Avoid waterlogging, as it can cause root rot.
Salvia ‘Blue Merced’ require light feeding in spring with a balanced slow-release fertiliser or compost. Tender salvias benefit from fertilisation every 2–4 weeks during the growing season using a liquid feed for flowering plants. Over-fertilising should be avoided, as it can encourage foliage growth at the expense of flowers.
Propagation of Salvia ‘Blue Merced’is prohibited without a licence
Salvia ‘Blue Merced’ should be trimmed around April or May, a technique often called the “Chelsea Chop,” once new shoots start to appear. Cut back to the fresh growth, and continue deadheading throughout the season. Vigorous varieties can be pruned again in July to encourage bushier, greener plants rather than tall, woody stems. Salvias should not be cut back in autumn, as leaving the foliage intact helps protect the plant from frost.
Salvia ‘Blue Merced’ moderately drought-tolerant once established, thriving in well-drained soil and full sun. Tender salvias are less drought-tolerant and require more consistent watering.
Salvia ‘Blue Merced’ performs well in UK gardens if given full sun and free-draining soil. It’s hardy in most areas, flowers for months in summer and autumn, and suits borders or containers. Avoid winter wet and prune lightly in spring.
