Lavandula × intermedia 'Provence' (Provence Lavandin)
Contents
Introduction & History
Provence Lavandin is a French selection prized for its exceptionally sweet essential oil — the finest oil quality among the lavandins, closest to true English lavender in fragrance. While 'Grosso' dominates oil production, 'Provence' is the choice for discerning growers who want lavandin's productivity with a gentler, sweeter scent better suited to perfumery and premium sachets.
History & Origin
Selected in the Provence region of France from natural lavandin populations. Developed for its superior oil quality — lower camphor content than 'Grosso,' producing a sweeter, more balanced essential oil closer to true lavender in character. Popular with artisan lavender growers and small-scale essential oil producers who prioritise fragrance quality over volume.
Botanical Description
Large sub-shrub growing 50–75 cm tall and 60–90 cm wide — slightly smaller than 'Grosso.' Flower spikes are medium violet-blue, graceful and slightly tapered. The overall habit is slightly more refined than 'Grosso,' with a mounding, dome-shaped form. Leaves are silvery-grey. The fragrance is sweeter and less camphoraceous than other lavandins — the most 'English lavender-like' lavandin.
Stem: Square (quadrangular) — diagnostic for Lamiaceae • Leaves: Opposite, decussate arrangement • Height: 60 cm at maturity • Spread: 75 cm • Foliage: grey-green • Flowers: pale purple (summer)
Planting & Cultivation
Same requirements as 'Grosso' but at slightly closer spacing (50–70 cm). Full sun, well-drained alkaline soil. Excellent for home gardens where the sweeter fragrance can be appreciated up close — unlike commercial 'Grosso' fields, 'Provence' rewards intimate garden planting.
| Sun exposure | Full Sun |
| Soil pH | 6.5-8.0 |
| Spacing | 75 cm |
| Seed depth | 3–6 mm (surface-sow if light-dependent germinator) |
| Water needs | Low |
| Soil type | Well-drained, humus-rich loam; add perlite or grit for drainage |
Cultivation Details
Same as other lavandins — full sun, lean soil, trim after flowering. The slightly smaller stature makes it more manageable in home gardens than 'Grosso.' Good for medium-sized informal hedges and border plantings. The refined fragrance makes it a premium choice for cottage gardens and cutting gardens.
Climate & Hardiness
Hardy to about −15°C (USDA zones 6–9). Same as 'Grosso.' Good heat and drought tolerance. Slightly more compact, so may be marginally better in containers. Same winter drainage requirements.
USDA zones: 5-9
Minimum temperature: -18°C
Drought tolerance: Yes — established plants tolerate dry spells
Seasonal Care
Same as 'Grosso.' Spring: trim; Summer: flowering peak; trim after bloom; Autumn/Winter: ensure drainage.
Propagation
Semi-hardwood cuttings only — sterile hybrid. Same technique as 'Grosso.' Cuttings root in 6–8 weeks in gritty compost.
| Method | Success rate | Time | Notes |
|---|---|---|---|
| Stem cuttings | 70–90% | 2—4 weeks | Softwood in spring, semi-ripe in summer; 8–12 cm |
| Division | 95%+ | Immediate | Split established clumps in spring or autumn |
| Seed | 50–80% | 14–28 days | Some require cold stratification; germination variable |
| Layering | 80–90% | 6–12 weeks | Pin low branch to soil; sever when rooted |
Diseases & Pests
Same as 'Grosso' and other lavandins. Root rot in wet soil, rosemary beetle. Generally healthy in well-drained conditions.
Culinary Uses
Better for cooking than 'Grosso' due to its lower camphor content and sweeter profile. Still not as fine as English lavender for the most delicate preparations, but a closer approximation. Good in baking, lavender sugar, and infused syrups where a sweet floral note is desired.
| Category | Pairing suggestions |
|---|---|
| Baking | Shortbread, scones, cakes |
| Preserves | Jelly, syrup, sugar |
| Cocktails | Gin botanicals, spritzers |
| Honey | Infused honey, dessert garnish |
Medicinal & Aromatherapy
The essential oil is the sweetest and most balanced of the lavandins — suitable for premium aromatherapy use, sachets, and personal care products. Less camphoraceous than 'Grosso,' making it more calming and less stimulating. Still not identical to true L. angustifolia oil, but the closest lavandin alternative.
| Compound | Properties |
|---|---|
| linalool | floral, calming |
| cineole | camphoraceous, expectorant |
| thymol | antiseptic, warm |
| carvacrol | pungent, antimicrobial |
| eugenol | clove-like, analgesic |
Container & Companion Growing
Container Growing
Better suited to containers than 'Grosso' due to slightly smaller size. Use 35+ litre pots with very gritty mix. Full sun. Water sparingly. The sweet fragrance on a patio or balcony is delightful.
• Minimum pot size: 30–40 cm Ø, 15 L+
• Excellent drainage essential; add perlite
• Use free-draining potting compost with 20–30% perlite or grit
• Ensure drainage holes; stand on pot feet to prevent waterlogging
• Feed with dilute liquid fertiliser (half-strength) every 2–3 weeks in growing season
Companion Planting
Same as other lavenders — roses, Mediterranean herbs, gravel garden companions. The sweeter fragrance makes it especially pleasant near seating areas and along paths where you brush past it.
| ✓ Good companions | Roses, Brassicas, Fruit trees |
| ✗ Avoid planting with | Mint (invasive neighbour) |
Common Mistakes to Avoid
Same as other lavandins. Expecting it to be identical to English lavender (it's still a lavandin hybrid, just a sweeter one). Planting too closely for its mature size. Not appreciating the quality difference between 'Provence' and 'Grosso' — they serve different purposes.
Harvesting & Preservation
Same harvest timing as 'Grosso.' The dried flowers have a sweeter, less camphoraceous scent — premium quality for sachets, potpourri, and gifts. The essential oil commands higher prices than 'Grosso' oil for artisan and perfumery use.
• Time of day: Early morning, after dew has evaporated but before intense midday heat volatilises essential oils
• Growth stage: Just before flowering, when essential oil concentration peaks. Once flowers open, the plant redirects energy from leaf production
• Season: Summer
• Part harvested: Flowers
• Harvest rule: Never remove more than ⅓ of the plant at once; this ensures continued vigorous regrowth
• Technique: Cut stems cleanly above a leaf node with sharp scissors or secateurs. Tearing damages tissue and invites disease
| Method | Process | Shelf life | Best for |
|---|---|---|---|
| Air drying | Tie bundles, hang upside down in warm, dark, airy space | 6–12 months | Most herbs |
| Oven / dehydrator | Spread on trays, 35–45°C until crisp | 6–12 months | Fleshy-leaved herbs |
| Freezing (whole) | Blanch 5s, ice bath, pat dry, freeze flat on tray | 6 months | Basil, chives, parsley |
| Freezing (oil cubes) | Chop fine, pack into ice cube tray, cover with olive oil | 6 months | Any culinary herb |
| Herb salt | Layer herb and coarse salt 1:4, dry and grind | 12+ months | Rosemary, thyme, sage |
| Infused vinegar | Pack jar, cover with warm vinegar, steep 2–4 weeks | 6 months | Tarragon, dill, basil |
| Infused oil | Fill jar with dried herb, cover with oil, steep 4–6 weeks | 3–6 months | Rosemary, thyme, chilli |
Frequently Asked Questions
How does Provence compare to Grosso?
'Provence' has sweeter, less camphoraceous oil — closer to English lavender quality. 'Grosso' produces more oil per plant. Choose 'Provence' for fragrance quality, 'Grosso' for volume. For home gardens, 'Provence' is often the better choice.
Is it as hardy as English lavender?
Slightly less hardy — zone 6 vs. zone 5. But it's more heat- and drought-tolerant. In hot-summer climates, it actually performs better than English lavender.
Can I use it for culinary lavender?
Better than 'Grosso' due to lower camphor, but English lavender ('Hidcote' or 'Munstead') is still superior for the most delicate culinary applications. 'Provence' works well in baked goods and robust infusions.
