1. Getting Started

French lavender, scientifically known as Lavandula dentata, is a popular flowering plant known for its aromatic fragrance and beautiful purple flowers. It is widely grown for its essential oil, which is used in the production of perfumes and fragrances. However, a common concern among lavender enthusiasts is its ability to withstand harsh winter conditions. In this article, we will explore whether French lavender can survive the winter months and provide useful tips to ensure its survival.

2. Understanding French Lavender

French lavender is native to the Mediterranean region and thrives in warm, sunny climates. It is a woody perennial shrub that can reach a height of about two to three feet. The plant is characterized by narrow, gray-green leaves and bright purple flowers that bloom from late spring to early summer.

While French lavender is more cold-tolerant than other lavender varieties, it is still susceptible to damage during harsh winter conditions. It is important to understand the plant’s natural habitat and growth requirements to assess its chances of survival in colder climates.

3. Factors Affecting Winter Survival

Several factors affect the winter survival of French Lavender. These include temperature, moisture, soil conditions, and plant maturity. While French lavender can tolerate light frosts and temperatures as low as 15°F (-9°C), prolonged exposure to freezing temperatures can be detrimental to its health.

Moisture is another important consideration. Excessive moisture, especially in poorly drained soils, can lead to root rot and increase the likelihood of frost damage. Adequate soil drainage, especially during the winter, is essential to prevent waterlogging and maintain the overall health of the plant.

The maturity of the lavender plant also plays a role in its winter survival. Young plants are generally more susceptible to cold damage than well-established, mature plants. Proper care and protection during their early stages can greatly improve their chances of surviving the winter.

4. Winter Care Tips for French Lavender

To improve the winter survival of French Lavender, here are some essential care tips:

  1. Prune: Before winter sets in, lightly prune the lavender plant to remove dead or damaged branches. This will help improve air circulation and reduce the risk of fungal disease.

  2. Mulch: Apply a layer of organic mulch, such as straw or wood chips, around the base of the plant. Mulching helps to insulate the soil, regulate temperature and retain moisture, protecting the roots from freezing temperatures.

  3. Drain the soil: Make sure lavender is planted in well-drained soil. If the soil tends to retain water, consider amending it with organic matter or creating raised beds to improve drainage.

  4. Watering: Reduce watering frequency during the winter to prevent waterlogging. Water only when the soil feels dry. Overwatering can cause root rot and weaken the plant’s ability to withstand freezing temperatures.

  5. Protective cover: In areas with extremely cold winters, consider covering lavender plants with a frost blanket or burlap to provide additional protection from freezing temperatures and harsh winds.

5. Overwintering Options

If you live in an area with harsh winters and are concerned about the survival of French Lavender, there are a few options to consider:

  1. Container Gardening: Planting French lavender in containers allows for more flexibility in overwintering. Move the containers to a protected location, such as a garage or basement, where the temperature remains above freezing. Make sure the plants receive adequate light during this time.

  2. Cold frames: Building a cold frame around the lavender plants helps create a microclimate that provides protection from cold temperatures and frost. It acts as a small greenhouse and can greatly increase the chances of survival.

  3. Indoor growing: Consider growing French lavender indoors during the winter months. Place the plants near a south-facing window or use supplemental grow lights to provide adequate light. Maintain proper humidity levels and avoid overwatering.

By implementing these strategies, you can increase the likelihood that your French lavender will survive the winter and enjoy its fragrance and beauty for years to come.


Although French lavender is relatively cold tolerant, its survival during the winter depends on several factors. Understanding its growing requirements, providing proper care, and taking the necessary precautions can greatly increase its chances of surviving freezing temperatures. By following the tips in this article, you can ensure the health and longevity of your French lavender plants, allowing you to enjoy their aromatic fragrance and contribute to your perfume and fragrance endeavors.


Will French lavender survive winter?

French lavender (Lavandula dentata) is a Mediterranean plant that is not very cold hardy and may struggle to survive harsh winter conditions in colder regions. However, with proper care and protection, it is possible to increase its chances of survival.

What are the ideal winter conditions for French lavender?

French lavender thrives in mild winter climates where temperatures rarely drop below freezing. It prefers well-draining soil and requires at least six hours of sunlight each day. In areas with colder winters, providing additional protection is crucial to help it survive.

How can I protect French lavender during winter?

To protect French lavender during winter, you can follow these steps:

– Mulch: Apply a layer of organic mulch around the base of the plant to insulate the roots and protect them from freezing temperatures.

– Shelter: If you’re expecting frost or extreme cold, consider covering the plant with a frost cloth or a protective structure like a cold frame.

– Potted lavender: If you have French lavender in pots, move them to a sheltered location like a garage or a greenhouse to provide extra protection.

What happens if French lavender is not protected during winter?

If French lavender is not protected during winter, it may experience damage or even die. Freezing temperatures can cause the plant’s cells to burst, leading to wilting, browning, and eventually death. Proper protection is essential to prevent such damage.

Can I grow French lavender in colder regions?

While French lavender is not well-suited for colder regions, it is still possible to grow it with additional care and protection. Consider planting it in containers so you can easily move it indoors during the coldest months. Alternatively, you can grow it as an annual and replant it every year.
