Plant information

Plant Description

Salvia ‘Carolus’, bred by Marc Vanlancker from Oudenaarde, Belgium, is a delightful perennial that brings profuse lilac flowers and fragrant green foliage to your garden from late spring through to autumn. Its tubular blooms rise gracefully above a tidy, bushy base, creating a striking yet soft display that works beautifully in borders, mixed perennial beds, or containers.

The nectar-rich flowers are highly attractive to bees, butterflies, and other pollinators, making ‘Carolus’ an excellent choice for wildlife-friendly gardens. Its aromatic foliage adds a subtle fragrance that enhances the sensory experience of your outdoor space.

This variety is drought-tolerant once established, thriving in sunny, well-drained locations with minimal maintenance. While hardy across much of the UK, providing protection during severe frost ensures it returns vigorously each spring. Occasional deadheading encourages a second wave of blooms and keeps the plant looking fresh throughout the season.

With its elegant lilac blooms, aromatic foliage, and compact, versatile habit, Salvia ‘Carolus’ is a dependable, pollinator-friendly perennial that adds long-lasting colour and charm to gardens of all sizes. It’s a perfect choice for gardeners seeking low-maintenance beauty combined with ecological value.

🌿 How to Care for Salvia microphylla ‘Carolus’

How do I prune Salvia microphylla ‘Carolus’?
Salvia microphylla ‘Carolus’ 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 microphylla ‘Carolus’ 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 microphylla ‘Carolus’ 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 microphylla ‘Carolus’ 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 microphylla ‘Carolus’is prohibited without a licence
Salvia microphylla ‘Carolus’ 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 microphylla ‘Carolus’ 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 microphylla ‘Carolus’ 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.
