Plant information

Plant Description

Bring radiant energy to your garden with Salvia microphylla ‘Heatwave Glimmer’, a lively perennial that shimmers with bright pink and soft white flowers. Blooming from early summer through to the first frost, this variety provides months of long-lasting colour that keeps borders, containers, and mixed plantings vibrant well into autumn.

‘Heatwave Glimmer’ is a magnet for bees, butterflies, and other pollinators, filling your garden with movement and life. Its aromatic green foliage adds texture and subtle fragrance, making it a delight not just to look at, but also to smell and touch.

With a neat, compact habit, this salvia fits perfectly in herbaceous borders or patio containers, offering structure while allowing neighbouring plants to shine. Thriving in full sun with well-drained soil, it is hardy and drought-tolerant once established, making it suitable for both beginner and experienced gardeners.

A light deadheading after flowering encourages a second wave of blooms, extending the season even further. While hardy in most UK gardens, it benefits from protection during exceptionally severe frost.

For those seeking vibrant, long-flowering colour and a pollinator-friendly perennial, Salvia microphylla ‘Heatwave Glimmer’ adds sparkle, resilience, and effortless beauty to any sunny garden space.

🌿 How to Care for Salvia microphylla ‘Heatwave Glimmer’

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