Lavandula stoechas (French Lavender (Spanish Lavender))
Lavandula stoechas (French Lavender (Spanish Lavender))
Contents
Introduction & History
French Lavender — confusingly also called Spanish Lavender — is the exotic, butterfly-eared member of the lavender family. Its distinctive flower heads are topped with showy, petal-like bracts (the 'rabbit ears' or 'butterfly wings') that give it an appearance unlike any other lavender. This Mediterranean native blooms earlier, longer, and more dramatically than English lavender, but demands warmer conditions and resents cold, wet winters.
History & Origin
Native to the western Mediterranean — Portugal, Spain, France, Italy, and North Africa. The common names are confusing: 'French lavender' in English, 'Spanish lavender' in parts of Europe, and 'butterfly lavender' in horticultural trade. It was the lavender species first known to the Romans and grows wild in enormous quantities in the maquis and garigue scrublands of the Mediterranean coast. Cultivated since antiquity.
Botanical Description
Compact, bushy evergreen shrub growing 40–70 cm tall and wide. Leaves are narrow, grey-green, and aromatic — slightly greener than English lavender. The distinctive flower heads are short, dense, pine-cone-shaped spikes topped by 2–4 large, showy sterile bracts (the 'ears') in purple, pink, or white. Blooms from early spring through summer — a much longer season than English lavender. The scent is stronger, more camphoraceous, and less sweet than L. angustifolia.
Stem: Square (quadrangular) — diagnostic for Lamiaceae • Leaves: Opposite, decussate arrangement • Height: 50 cm at maturity • Spread: 50 cm • Foliage: grey-green • Flowers: deep purple (spring-summer)
Planting & Cultivation
Plant nursery-grown specimens in spring, spacing 40–60 cm apart. Full sun and exceptionally well-drained soil — this is the most drainage-sensitive lavender. In heavy soil, grow exclusively in raised beds or containers. Acid to neutral soil preferred (unlike English lavender, it tolerates acidity). Position against warm walls in marginal climates. In Mediterranean climates, it naturalises effortlessly.
| Sun exposure | Full Sun |
| Soil pH | 6.0-8.0 |
| Spacing | 50 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
Full sun, perfect drainage, no fertiliser, and warmth. Deadhead continuously for a bloom season extending from spring through autumn. Prune lightly after each flush of flowers. More vigorous and faster-growing than English lavender. In warm climates, it can bloom for 6–8 months. The showy bracts make it far more ornamental than English lavender, but the more camphoraceous oil is less valued for aromatherapy and cooking.
Climate & Hardiness
Hardy to only about −7°C (USDA zones 8–10). Much more tender than English lavender. In zones 7 and colder, grow as a container plant overwintered frost-free. Thrives in the same conditions as citrus — warm, dry, Mediterranean. In coastal California, Mediterranean Europe, and similar climates, it grows effortlessly and blooms almost year-round.
USDA zones: 7-10
Minimum temperature: -10°C
Drought tolerance: Yes — established plants tolerate dry spells
Seasonal Care
Spring: flowering begins — one of the earliest lavenders. Summer: continuous bloom; deadhead regularly. Autumn: may still be flowering; final light trim. Winter: protect from frost; in containers, move to a bright, frost-free position. In zones 9–10, evergreen and may flower into winter.
Propagation
By semi-hardwood cuttings in summer (8–10 cm tips). Also germinates from seed (surface-sow, 14–21 days at 18–20°C) — more reliably from seed than English lavender. Self-sows in warm climates. Named cultivars must be cutting-propagated.
| 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
Root rot is the primary concern. Otherwise very pest-free. In warm climates, essentially trouble-free. In cool, humid conditions, fungal issues on the dense flower heads are possible. Provide excellent air circulation.
Culinary Uses
Not traditionally a culinary lavender — the high camphor content gives a harsh, medicinal taste in food. English lavender (L. angustifolia) is far superior for cooking. Occasionally, the flowers are used as a visual garnish (they're stunning on plates) but the flavour is too strong for most culinary applications.
| 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 high in camphor, fenchone, and 1,8-cineole — more stimulating and camphoraceous than English lavender oil. Used in traditional Mediterranean folk medicine for headaches, respiratory complaints, and as an insect repellent. The oil is used in cleaning products and strong aromatherapy blends rather than for calming purposes.
| Compound | Properties |
|---|---|
| linalool | floral, calming |
| cineole | camphoraceous, expectorant |
| thymol | antiseptic, warm |
| carvacrol | pungent, antimicrobial |
| eugenol | clove-like, analgesic |
Container & Companion Growing
Container Growing
Excellent container plant — and in cold climates, the only practical way to grow it. Use terracotta with very gritty mix. Full sun. Water sparingly. The showy flowers make it a dramatic patio specimen from spring through autumn. Overwinter frost-free.
• 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
Stunning with other Mediterranean plants: rosemary, cistus, Convolvulus cneorum, and agapanthus. The exotic flower form makes it a specimen plant rather than a massed hedging plant. Excellent in containers on patios and courtyards. Attracts bees throughout its long flowering season.

Common Mistakes to Avoid
Planting outdoors in cold climates and losing it to winter frost. Expecting it to taste like English lavender in cooking (it doesn't — far too camphoraceous). Not deadheading, which shortens the spectacular bloom season. Confusing the common names: 'French lavender' = L. stoechas, not L. dentata.
Harvesting & Preservation
Harvest flower heads for dried arrangements and sachets. The scent is more camphoraceous and stronger than English lavender — potent in sachets and moth-repelling bundles. Less suited to culinary use due to the high camphor content. The distinctive 'eared' flower heads are beautiful in dried arrangements.
• 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: Spring-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
Why does it have 'rabbit ears' on the flowers?
The showy structures are sterile bracts — modified leaves that attract pollinators by being more visible than the tiny true flowers below. They evolved as a pollinator signal and give L. stoechas its distinctive appearance.
Will it survive winter in my garden?
Only in zones 8–10 (minimum −7°C). In colder zones, grow in containers and bring inside before frost. It needs protection from both cold and wet — winter drainage is critical even in mild climates.
Is French lavender the same as the purple fields of Provence?
No — those fields are lavandin (L. × intermedia 'Grosso') or true lavender (L. angustifolia) at higher elevations. French lavender (L. stoechas) grows wild in the Mediterranean maquis scrub but is not used for field-scale essential oil production.
