Growing Lavender in Scotland: The Complete Guide

Lavandula angustifolia (English lavender)

Lavender is genuinely marginal in Scotland, but not for the reason many gardeners assume: English lavender is hardy enough to overwinterKeeping a plant alive and intact through the cold months, whether left outdoors, moved under cover, or stored dormant. Full definition → outdoors, and the real risk is wet, heavy soil, not cold. French and Spanish types are a different story entirely, with a real hardiness gap that changes which one to choose on acid soil.

A grey, aromatic, evergreen shrub that stays compact for years given the right ground, lavender wants poor, free-drainingSoil that lets water pass through quickly rather than pooling, so roots aren't sitting in wet ground after rain. Full definition → soil rather than a rich, well-fed bed: the opposite of what most border plants ask for.

Site and soil

Choose a spot in full sun with free-draining soil, ideally neutral to alkaline and on the poorer, less fertile side; avoid heavy clay, waterlogged ground, shade and damp spots altogether. On acid soil, French lavender is the better-suited type, though it's also the more tender one, better grown in a movable container than planted straight into open ground here. Space plants 90cm apart as individual specimens, or 30-45cm apart for a hedge. For containers, use a 30-40cm diameter pot with drainage holes, filled with peat-freeCompost made without peat, which is harvested from a slow-forming, carbon-storing wetland habitat that peat extraction damages.

Planting and propagation

Plant April to May, going into the ground immediately after buying, and water regularly through the first growing season, especially in dry weather. Propagate by softwood or semi-ripe cuttings in early to midsummer, or hardwood cuttings in late autumn after flowering. Seed is possible too, collected from dried seedheads in late summer and sown in spring, but a named cultivarA plant variety that arose or was bred under cultivation and is kept true by deliberate propagation, rather than a naturally occurring wild species. Full definition →'s seed may not resemble the parent plant, so cuttings are the more reliable route for keeping a specific variety true.

Care through the year

Established ground plants are drought-tolerant and need no feeding, since lavender actually prefers low-nutrient soil; container plants need watering once or twice weekly in dry summer weather. Prune annually in late summer after flowering, removing spent flower stalks and about 2.5cm of leaf growth, and never cut into woody stems. Older plants naturally become straggly and woody; since lavender establishes quickly from new stock, replacing an old plant is usually more effective than trying to rejuvenate it.

Winter

English lavender in free-draining soil needs no special winter protection at all. Container plants of any type should be kept fairly dry and sheltered from excess rain over winter. French, Spanish and other tender types genuinely need moving somewhere frost-free for winter, since they're less hardy and shorter-lived outdoors than English lavender.

Harvesting

Cut flower spikes in early to mid-summer, just before they're fully open, for the strongest fragrance.

Varieties

Ten AGMThe RHS's Award of Garden Merit: a UK-wide trials award for reliable performance, not a Scotland-specific recommendation. Full definition → varieties exist across English, hybrid and Spanish types. English cultivars (Hidcote, Imperial Gem, Miss Katherine, Beechwood Blue) all carry H5 hardiness, not just an award; hybrid and Spanish AGM cultivars on the same list range down to H3The RHS's H1a–H7 scale for how much cold a plant can survive outdoors, H1a being tender indoor-only and H7 hardy anywhere in the UK.

Common problems

• Root rot follows wet or heavy soil far more often than any pest does; raised beds or containers with sharp drainage are the real defence.
• Rosemary beetle is a metallic purple-and-green beetle that chews leaves and flowers down to greyish stumps; plant health usually isn't affected, and hand-picking beetles and larvae off keeps numbers down.
• Sage and Ligurian leafhopper causes pale mottling on leaves, usually cosmetic rather than serious.
