Salvia lavandulifolia forms a neat, woody-based mound of narrow, downy grey-green leaves that release a pleasant scent when brushed. In midsummer, upright spikes of violet-blue to pale mauve flowers rise above the foliage, attracting bees and other pollinating insects.
Reaching around 60cm (2ft) tall and wide, it suits gravel gardens, Mediterranean-style planting and the front of a sunny border, where its silvery foliage contrasts beautifully with brighter flowers. Plant in full sun and well-drained soil, as good drainage is especially important through the UK winter.
How to care for Salvia lavandulifolia:
When planting, improve drainage by incorporating compost and adding horticultural grit or sand to heavier soils. Space plants 30-45cm (12-18in) apart and water thoroughly.
Deadhead spent flower spikes promptly to encourage continuous blooming. Apply a 5-7cm (2-3in) mulch of composted bark or gravel in early spring to retain moisture and suppress weeds, but avoid manure-based mulches, which can be too rich.
Feed with a high-potash fertiliser, such as tomato feed, once growth resumes in spring to promote flowering. Water regularly during dry spells but ensure the soil remains well-drained to prevent root rot.
In colder regions, it may die back, so provide winter protection by applying a dry mulch around the base or lifting and potting up plants to overwinter in a frost-free location.
