French Lavender vs. English Lavender: A Complete Comparison for Gardeners and Enthusiasts
Introduction
Lavender captivates gardeners and aromatherapists alike with its silvery foliage, fragrant blossoms, and versatility in the landscape, kitchen, and medicine cabinet. Two of the most popular species—French lavender (Lavandula stoechas and related hybrids) and English lavender (Lavandula angustifolia)—often vie for space in borders, containers, and cutting gardens. While they share many traits, key differences in appearance, hardiness, fragrance, and uses mean choosing the right type can make or break your lavender success. In this comprehensive guide, we’ll dissect French vs. English lavender across every dimension—botany, climate adaptability, cultivation practices, oil composition, pest and disease resistance, and culinary and therapeutic applications—so you can select and grow your ideal lavender variety.

Botanical Origins and Classification
English lavender (Lavandula angustifolia) and French lavender (Lavandula stoechas, often called Spanish lavender in trade) belong to the Lamiaceae or mint family.
English Lavender
- Native to the mountainous regions of the Mediterranean (Pyrenees, Italy).
- True species with narrow, linear leaves and spikes of tubular flowers.
- Taxonomically, L. angustifolia comprises varieties like ‘Hidcote’, ‘Munstead’, and ‘Vera’.
French Lavender
- Includes L. stoechas and interspecific hybrids like L. × stoechas ‘Otto Quast’.
- Native to the Mediterranean basin, especially Spain and Portugal.
- Distinguished by showy “rabbit-ear” bracts atop the flower spikes.
While both trace their ancestry to similar climates, French lavender hybrids exhibit more vigorous growth and unique flower forms than the more uniform English species.
Growth Habit and Landscape Uses
English Lavender
- Forms compact mounds 30–60 cm tall and wide.
- Ideal for low hedges, edging, and mass plantings.
- Maintains neat shape with annual pruning.
French Lavender
- Often larger, 50–90 cm tall and up to 1 m wide.
- Suited to mixed perennial borders, gravel gardens, and containers.
- Flower bracts add vertical accents above foliage.
Gardeners choose English lavender for formal layouts and edible landscapes; French lavender for architectural interest and pollinator gardens.
Flower Morphology and Bloom Season
English Lavender
- Flower spikes bear densely arranged, small tubular flowers.
- Colors range from deep violet to pale lilac and white.
- Blooms in early to mid-summer (June–July), with possible rebloom in late summer.
French Lavender
- Flower spikes topped by conspicuous petal-like bracts (“ears”).
- Bracts may be purple, pink, or white, contrasting with darker flower spikes.
- Bloom period extends from late spring into autumn, often with multiple flushes.
The distinctive bracts of French lavender offer long-lasting visual interest, while English lavender’s classic spikes suit cutting for arrangements.
Climate Adaptability and Hardiness
Temperature Tolerance
- English Lavender: Hardy to USDA zone 5 (–20 °C). Thrives in cooler, maritime climates.
- French Lavender: Hardy to USDA zone 7 (–15 °C). Prefers warmer, drier conditions.
Humidity and Rainfall
- English lavender tolerates moderate rainfall; French lavender performs best in dry sites.
- In humid zones, English lavender less prone to crown rot, whereas French lavender may suffer fungal issues.
Selecting species aligned with local climate ensures plant longevity and reduces winter damage or summer stress.
Soil Preferences and Cultural Requirements
Both species share a preference for:
- Full sun (minimum 6–8 hours daily).
- Well-draining soils (pH 6.7–7.3).
- Low to moderate fertility; excessive nitrogen leads to leggy growth.
English Lavender
- Adapts to heavier soils if drainage is amended with grit or sand.
- Performs well in raised beds and rock gardens.
French Lavender
- Requires exceptionally free-draining soils; raised beds or gravel mulch ideal.
- Sensitive to prolonged soil moisture; avoid planting in clay without heavy amendments.
Amending soil with coarse materials and planting on slopes or mounds enhances drainage for both species.
Fragrance Profile and Essential Oil Composition
English Lavender
- Oils rich in linalool and linalyl acetate, yielding a sweet, floral aroma prized in perfumery and aromatherapy.
- Yields average 2–3% essential oil by weight.
French Lavender
- Oils contain higher percentages of camphor, 1,8-cineole, and borneol, conferring a sharper, more medicinal note.
- Yields greater oil quantity (3–4%), favored for soaps and cleaning products.
Understanding oil chemistry guides uses: English lavender for calming blends, French lavender for invigorating or antimicrobial formulations.
Culinary and Health Applications
English lavender’s sweeter fragrance makes it the primary choice for:
- Lavender sugar, baked goods, herbal teas, and scones.
- Soothing sleep-promoting linen sprays and bath blends.
French lavender, with its robust essential oil, suits:
- Topical antiseptics, soaps, and insect repellents.
- Culinary uses limited by higher camphor content; best in small doses as garnish or infused oils.
Flavor and oil strength dictate suitability: English lavender for subtle culinary infusions, French lavender for functional cosmetic and household products.
Pests, Diseases, and Maintenance
Common Pests
- Aphids and spittlebugs may infest both types; control with strong water sprays or insecticidal soaps.
- Lavender leafhoppers occasionally target French lavender in warm climates.
Diseases
- Phytophthora root rot in poorly drained soils—French lavender more susceptible.
- Septoria leaf spot and powdery mildew in humid regions—English lavender more resilient.
Pruning and Renewal
- Prune in early spring or late summer after bloom, cutting back one-third but avoiding cutting into old wood.
- Renewal pruning every 3–4 years rejuvenates overcrowded clumps, especially in English lavender.
Regular sanitation and site selection mitigate disease risks, prolonging plant health.
Propagation and Sourcing Varieties
Propagation Methods
- Cuttings: Hardwood cuttings in autumn for root-true offspring.
- Division: Possible with established English lavender clumps; less reliable for French lavender.
Popular Cultivars
- English Lavender: ‘Hidcote’, ‘Munstead’, ‘Vera’.
- French Lavender: ‘Otto Quast’, ‘Anouk’, ‘Ribbon Purple’.
Purchase from reputable nurseries to ensure accurate labeling and disease-free stock.
Conclusion
French and English lavender each bring unique strengths to the garden and beyond. English lavender shines in formal borders, edible landscapes, and calming aromatic applications, thanks to its sweet fragrance and cold tolerance. French lavender enthralls with dramatic bracts, generous oil yields, and robust suitability for soaps, cleaners, and insect-repellent blends—so long as you provide sharp drainage and a warm site. By aligning species choice with climate, soil, and intended use, gardeners and artisans can harness the full potential of lavender’s timeless appeal.
Top 10 Questions & Answers
- Which lavender is hardier, English or French?
English lavender tolerates colder climates (USDA zone 5) compared to French lavender (zone 7). - Can I use French lavender in baking?
Its high camphor content makes French lavender less suited for culinary use; use English lavender instead. - Which lavender oil is best for stress relief?
English lavender oil, rich in linalool and linalyl acetate, has stronger sedative and anxiolytic properties. - Why did my French lavender rot?
