Did You Know?
1. While lavender is known for its resilient nature, not all varieties can survive harsh winter conditions. However, the English lavender (Lavandula angustifolia) has a higher chance of survival during winter compared to other types.
2. In some regions, such as the Pacific Northwest in the United States, lavender plants can be placed in a sheltered spot or covered with a layer of mulch to increase their chances of surviving winter.
3. Lavender plants are actually native to the Mediterranean region, where they are exposed to mild winters. This is why some varieties may struggle when faced with extremely cold temperatures and frost.
4. In colder climates, growing lavender in containers can be an effective way to protect the plant during winter. By moving the container indoors or into a more sheltered location, you can save your lavender from severe winter damage.
5. Despite its delicate appearance, lavender plants have natural anti-freeze properties. Their oils contain constituents that can protect their tissues from freezing, allowing some varieties to survive and bounce back even after a snowy winter.
Winter Survival Of Lavender Species
Lavender, with its aromatic scent and beautiful purple flowers, is a hardy plant that can survive harsh winter conditions. However, there are factors to consider for ensuring the survival of lavender plants during winter.
One important consideration is the type of lavender species being grown. English lavender species, especially Lavandula angustifolia, are cold-hardy and can withstand winter temperatures. These varieties are suitable for colder climates, with the Hidcote Superior variety reportedly tolerating temperatures as low as -30 °C (-20 °F).
On the other hand, Spanish, French, and Italian lavenders are less tolerant of cold and are better suited for mild Mediterranean winters. In colder climates with regular winter frosts, these varieties should be transferred to pots and taken indoors before the first frost.
- To ensure the survival of lavender plants during winter:
- Choose cold-hardy species like English lavender and Lavandula angustifolia.
- Consider the Hidcote Superior variety for extremely low temperatures.
- Transfer Spanish, French, and Italian lavenders to pots and bring them indoors before the first frost.

Frost Tolerance Of Different Lavender Varieties
The frost tolerance of lavender depends on the specific variety being grown. English lavender species are hardy and can survive outdoors throughout winter, tolerating frost with ease. This makes them suitable for colder climates where temperatures can drop significantly during winter months.
However, Spanish, French, and Italian lavenders are not frost tolerant and should be protected from freezing temperatures. These varieties should be transferred to pots and brought indoors over winter in climates with regular frosts.
Taking the necessary precautions to protect non-English lavenders from frost will ensure their survival and well-being during the winter months.
Importance Of Soil Drainage For Lavender In Winter
The survival of lavender plants during winter is greatly influenced by the condition of the soil. Lavenders generally thrive in well-draining soils and are able to withstand drought-like conditions. However, in colder climates where rainfall is higher, they are more prone to diseases such as root rot.
To prevent root rot, it is important to improve the soil’s drainage by adding sand or gravel. A recommended soil mix ratio is usually 70% potting soil and 30% sand or gravel. In colder climates, a 50:50 mix might be necessary to ensure optimal drainage.
Another option to consider is growing lavenders in pots, as this can enhance drainage and reduce the risk of root rot. By providing suitable soil conditions, lavender plants can successfully endure the winter without succumbing to diseases caused by excess moisture.
- Amend the soil with sand or gravel to improve drainage
- Recommended soil mix ratio: 70% potting soil, 30% sand or gravel
- In colder climates, consider a 50:50 mix for proper drainage
- Growing lavenders in pots enhances drainage and reduces the risk of root rot.
Pruning Techniques To Protect Lavender In Winter
Proper pruning is vital to protect lavender plants during winter and prolong their lifespan. Lavenders that haven’t been pruned are more prone to splitting in winter due to the weight of snow and ice on the branches.
Regular pruning not only prevents splitting but also promotes new growth and maintains an attractive shape. It is recommended to prune lavender plants twice a year, in early spring and late summer.
In early spring, about a third of the soft green growth should be removed to shape the lavender into a compact mound. This helps to delay the formation of woody stems, which are less resilient and prone to breaking in winter.
Late summer pruning focuses on trimming back spent flower stems to maintain a tidy appearance during winter. It also promotes the growth of new stems for the following year’s blooms.
It is crucial to avoid cutting into woody stems during pruning, as they are unlikely to produce new growth and may even lead to the death of the plant. By following proper pruning techniques, lavender plants can be protected from winter damage and encouraged to thrive.
Lifespan And Care Of Lavender Species In Cold Climates
It is important to note that lavender plants, even with proper care, may have a limited lifespan in cold climates. Some lavender species may only live for four years, even with optimal care.
To extend the lifespan of lavender plants in cold climates, it is essential to provide the appropriate growing conditions, including well-draining soil and regular pruning. By ensuring good soil drainage and protecting the plants from winter damage, lavender plants can thrive and potentially exceed their expected lifespan.
English lavender species, in particular, are known for their cold-hardiness and ability to survive winters in colder climates. With the right care, these varieties can flourish and bring beauty and fragrance to gardens even in the coldest of winters.
the survival of lavender plants during winter largely depends on their species, frost tolerance, soil drainage, and proper pruning techniques.
- English lavender species are hardy and can survive outdoors throughout winter, tolerating frost with ease.
- Spanish, French, and Italian lavenders are not frost tolerant and should be protected from freezing temperatures.
- Suitable soil conditions, including good drainage, are crucial to prevent root rot during winter.
- Regular pruning promotes the health and longevity of lavender plants.
By following these expert tips and strategies, lavender enthusiasts can ensure the survival and thriving of their plants even in cold climates.
