How to Grow Lavender: Lessons from Provence
A plant that earns its place
Lavender gives a garden immediate structure. Its silver-grey foliage catches the light, and its flower spikes lift borders and beds with colour and relief. It belongs naturally in open, sun-drenched landscapes — and it brings that quality with it wherever it grows.
When it flowers, lavender does quiet, useful work. That fragrance does something practical, too. Aphids tend to avoid it. Near plants that are more susceptible to infestations, lavender provides a kind of quiet protection that works without any effort on your part.
The flowers produce nectar and pollen in quantities that bees notice immediately. Within a few weeks of planting, the garden becomes more alive — busier, better pollinated, more itself.
True lavender or lavandin?
Not all lavenders behave the same way, and the difference matters more than most people expect.
True lavender — lavande fine — is a mountain plant. Wild populations grow above 800 metres in Haute-Provence, on dry, chalky soils where water drains fast and summers run long and hot. The fragrance is what made its name in perfumery — subtle and layered in a way that lavandin simply isn't. Hardy and frost-resistant, it establishes durably when conditions suit it. Many nursery selections today extend cultivation to lower altitudes, with clones selected for different sizes, flower tones and growth habits — each with its own preferences, so reading descriptions carefully before buying pays off.
Lavandin (Lavandula × intermedia) fills the great fields of the Luberon — and is what most nurseries sell when they label something simply "lavender." A natural hybrid, it establishes faster and grows considerably larger than true lavender. It produces long flower spikes and adapts to a wider range of conditions; altitude is not a factor. For gardeners who want visual impact quickly, lavandin is the most straightforward choice.
The right moment to plant
Spring suits pot-grown plants best. April through June, the soil is warming and roots settle in properly. A plant in the ground by May has most of the season ahead of it before the cold arrives.
In Provence, autumn planting also works well, provided the ground drains freely. Summer planting, in any climate, makes establishment considerably harder.
Cuttings go into open ground after the last frosts, or at the beginning of autumn. When they take well, they often give a full season's head start on growth.
True lavender seeds are uncommon. When you do have them, sow at the beginning of winter directly into open ground, leaving the seeds uncovered. Cold temperatures trigger germination naturally in spring — the plant following its own rhythm.
The one thing lavender genuinely needs
Well-drained soil. More than sun, more than warmth, more than any particular soil type — lavender demands ground that does not hold water. On the limestone plateaux where lavender grows wild, rain drains before it has time to pool. That is what the roots expect. In permanently damp soil, the plant gradually deteriorates — and rarely comes back from it. Sandy or chalky ground works well without any adjustment. Heavier soil benefits from added grit, or from raising the planting level slightly.
Full sun completes the picture. A south-facing position produces the most generous flowering and keeps the plant compact and balanced.
Watering your garden lavender
Water well at planting, then gradually step back. Once established, lavender largely takes care of itself. Rainfall does most of the work. A long dry spell occasionally calls for a deep watering — but that is the exception, not the rule.
Overwatering is by far the most common reason lavender fails in garden settings. The plant's entire history is one of dry summers and fast-draining soil. Trusting that history is usually the right instinct.
What to plant alongside lavender
Planted alongside rosemary and thyme, lavender forms a border that smells of the garrigue and looks after itself. The plants share the same requirements and attract the same pollinators. Very little management is needed once they are established. The scent also keeps aphids at a distance, which benefits whatever happens to be growing nearby.
How the museum cares for its lavender
At the Musée de la Lavande, the garden lavender is mulched with ramial chipped wood — a mulch made from young branches that feeds the soil slowly as it breaks down. It reduces moisture loss through summer, protects soil life through winter and removes the need to dig or disturb the earth mechanically. The result is healthier roots and plants that remain vigorous over time.
Soil that is too rich actually works against lavender. The plant comes from thin, hungry ground, and performs best in similar conditions. An organic fertiliser does no harm applied occasionally — though most established plants simply won't use it. For compost, a Mediterranean-blend mix is the right choice: it drains properly and keeps the plant from being overfed.
What keeps lavender producing
Left unpruned, lavender turns woody within a few seasons and stops flowering. Cut back regularly — at the right time — the same plant can produce well for fifteen years or more. Our guide to pruning lavender covers what to do and when.
The Musée de la Lavande in Cabrières d'Avignon, near Gordes, is the place to see all of this in practice. Book your visit.
