How to Grow Salvias in the UK: Complete Growing Guide

Growing salvias in the UK is one of the best ways to introduce spectacular colour, long-lasting flowers and pollinator-friendly planting into your garden or allotment.

Salvias are available in an enormous range of colours, including purple, blue, red, pink, white and combinations of several shades.

Some produce tall spikes of flowers, while others develop bushy plants covered in colourful blooms.

One of the biggest advantages of salvias is their exceptionally long flowering season.

Depending on the variety, salvias can flower from late spring through summer and into autumn, sometimes continuing until the first significant frosts.

They’re particularly popular with bees, making them excellent additions to wildlife-friendly gardens.

Here at Gardening with Ben, I enjoy growing salvias because they provide so much colour over such a long period.

Varieties such as Salvia ‘Amistad’ and Salvia ‘Hot Lips’ are particularly attractive, producing distinctive flowers that can brighten borders and containers throughout summer.

However, one of the most important things to understand is that not all salvias have the same growing requirements.

Some are hardy perennials that survive normal UK winters without difficulty.

Others are tender or borderline hardy and may need protection from frost.

Pruning requirements also vary between different types.

In this complete UK growing guide, we’ll explore everything you need to know about growing salvias successfully.

We’ll cover choosing varieties, planting, soil requirements, watering, feeding, pruning, taking cuttings, growing salvias in pots, winter protection and common problems.

We’ll also explain how to keep salvias flowering and which varieties are particularly attractive to bees.

What Are Salvias?

Salvias belong to the genus Salvia, part of the Lamiaceae or mint family.

This large genus includes hundreds of species and numerous cultivated varieties.

Salvias originate from many parts of the world, including Europe, Asia and the Americas.

Some are herbaceous perennials, while others are shrubs, subshrubs or annuals.

Are Salvias Perennials?

Many salvias are perennial plants.

However, their winter hardiness varies considerably.

Are All Salvias Hardy in the UK?

No.

Some varieties are reliably hardy, while others need winter protection.

Is Sage a Salvia?

Yes.

Common culinary sage is Salvia officinalis.

However, ornamental salvias are generally grown for their colourful flowers rather than their culinary uses.
