What Is French Lavender?
French lavender belongs to the species Lavandula stoechas. It is native to the Mediterranean region and thrives in warm, sunny, dry environments.
Unlike English lavender, French lavender has:
- Shorter flower spikes
- Distinctive upright bracts (“rabbit ears”)
- A stronger, slightly more camphor-like scent
- Less tolerance to cold and wet conditions
Because of this, French lavender is often grown in pots so it can be protected in winter.
Why Grow French Lavender?
French lavender is popular for many reasons:
- Unique, decorative flowers
- Long flowering season
- Strong fragrance
- Excellent for pots and containers
- Attractive to bees and pollinators
- Ideal for patios, balconies, and doorways
It offers visual impact that other lavender types don’t.
Best Position for French Lavender
Sunlight
French lavender must have full sun.
- Minimum 6–8 hours of direct sunlight daily
- Sun is essential for flowering and compact growth
- Shade causes weak stems and poor flowering
A south- or west-facing position is ideal.
Soil Requirements
Drainage is absolutely critical for French lavender.
Ideal Soil
- Free-draining
- Sandy or gritty
- Neutral to alkaline
Avoid
- Heavy clay soil
- Rich, compost-heavy soil
- Waterlogged ground
If planting in the ground, amend soil heavily with grit. Pots are often the safest option.
How to Plant French Lavender
Planting in Pots (Recommended)
- Choose a terracotta pot with drainage holes
- Add crocks or gravel to the base
- Use gritty compost (multi-purpose mixed with grit or sand)
- Plant with the base slightly above soil level
- Firm gently and water lightly once
Terracotta pots help compost dry faster, which French lavender prefers.
Planting in the Ground
Only recommended in well-drained soil and mild climates. Raised beds or slopes work best.
Watering French Lavender
French lavender is drought tolerant once established.
After Planting
- Water lightly once
- Allow soil to dry fully before watering again
Ongoing Care
- Water only during prolonged dry periods
- In pots, water only when compost is completely dry
- Never water little and often
Overwatering is the most common cause of death.
Feeding French Lavender
French lavender needs very little feeding.
- Avoid high-nitrogen fertilisers
- Do not add manure or rich compost
- Feeding is usually unnecessary
If growth is weak, a light, low-nitrogen feed once in spring is sufficient.
Pruning French Lavender (Very Important)
Pruning keeps French lavender compact and encourages repeat flowering.
When to Prune
- Light prune after flowering
- Main prune in late summer or early autumn
- Avoid heavy pruning in late autumn or winter
How to Prune
- Cut back spent flower stems
- Shape the plant lightly
- Always leave green growth
- Never cut into woody stems
Correct pruning prevents legginess and extends the plant’s life.
Flowering Season
French lavender often flowers earlier than English lavender, usually from late spring into summer. With regular deadheading, it can flower repeatedly.
Removing spent blooms encourages further flowering.
Winter Care for French Lavender
French lavender is not fully hardy in colder climates.
In Mild Areas
- Needs excellent drainage
- Protect from excessive winter rain
In Cold or Wet Areas
- Grow in pots
- Move to a bright, sheltered position in winter
- Keep compost mostly dry
- Protect from frost
Cold combined with wet soil is the biggest winter killer.
Common Problems and Solutions
Yellow Leaves
Usually caused by overwatering or poor drainage.
Wilting Despite Water
Often root rot — improve drainage immediately.
Few or No Flowers
- Not enough sun
- Overfeeding
- Incorrect pruning
Woody Growth
Caused by lack of regular pruning.
French lavender rarely suffers from pests; most issues are environmental.
French Lavender vs English Lavender
| Feature | French Lavender | English Lavender |
|---|---|---|
| Hardiness | Less hardy | Very hardy |
| Flower shape | Short spikes with bracts | Long flower spikes |
| Scent | Strong, slightly sharp | Sweet, classic |
| Best grown | Pots, mild climates | Ground or pots |
| Winter care | Needs protection | Usually fine outdoors |
Can You Grow French Lavender Indoors?
French lavender is best outdoors.
If grown indoors short-term:
- Place in the brightest window possible
- Ensure excellent drainage
- Water very sparingly
- Provide airflow
Long-term indoor growing is difficult due to light levels.
Benefits of French Lavender
- Decorative, unusual flowers
- Strong fragrance
- Pollinator friendly
- Drought tolerant
- Low maintenance once established
It is ideal for ornamental use rather than culinary purposes.
Final Thoughts
French lavender is a stunning and rewarding plant when grown correctly. Its success depends on full sun, excellent drainage, minimal watering, and proper pruning. While it requires more winter protection than English lavender, growing it in pots makes care easy and reliable.
With the right conditions, French lavender will provide long-lasting colour, fragrance, and structure to patios and sunny garden spaces.
