Plant information

Plant Description

Salvia ‘Big Sky’ is a spectacular perennial that stands out in any garden with its super-sized violet-blue flower spikes rising from a dense rosette of large, aromatic green leaves. Unlike many perennial salvias, it blooms later in the season, offering a unique and extended floral display that keeps borders, containers, and mixed perennial beds vibrant from late spring to early summer.

This variety combines bold structure with long-lasting beauty. The upright flower spikes are not only visually striking but also attract bees, butterflies, and other pollinators, enhancing the biodiversity and liveliness of your garden. Its aromatic foliage adds texture and subtle fragrance, creating both sensory and visual appeal.

Salvia ‘Big Sky’ thrives in full sun with well-drained soil and requires minimal care. Once established, it is both heat- and drought-tolerant, needing only occasional watering to maintain its vibrant flower display. Its robust habit makes it ideal for sunny borders, patio containers, or as a statement plant in mixed beds.

With its long-lasting violet-blue blooms, aromatic foliage, and easy-care nature, Salvia ‘Big Sky’ is perfect for gardeners seeking dramatic colour, pollinator appeal, and minimal maintenance. It’s a reliable, show-stopping addition to any sunny garden.

🌿 How to Care for Salvia ‘Big Sky’

How do I prune Salvia ‘Big Sky’?
Salvia ‘Big Sky’ 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 ‘Big Sky’ 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 ‘Big Sky’ 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 ‘Big Sky’ 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 ‘Big Sky’is prohibited without a licence
Salvia ‘Big Sky’ 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 ‘Big Sky’ 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 ‘Big Sky’ 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.
