Choose the Right

If you live in a cold climate, you'll need to choose a variety of lavender that can withstand the deep freezes. English lavenders and Lavandin hybrids are the most cold-friendly categories.

For northern growers, English lavender and Lavandin hybrids are the way to go. They're more resistant to frost than French varieties.

In zones 7 and below, you'll need to choose from English lavender and Lavandin hybrids. They're specifically bred for cold hardiness.

If you're growing in containers, you'll need a dwarf variety that can thrive in a pot. This will help your lavender plant survive the winter months.

English lavender, or Lavandula angustifolia, is more tolerant to frost and will do better throughout the winter.

Planting and Timing

Lavender plants need to be established in the warm spring and summer months to survive cold winters. Young plants can be transplanted outdoors after the danger of frost has passed.

Consistent water and well-drained soil are crucial for encouraging quick root growth in young lavender plants. This allows them to establish a strong foundation for future growth.

Plant Life Cycle

Lavender is a perennial plant, meaning it will come back year after year if properly cared for.

It's worth noting that perennial plants typically require less maintenance than annuals, as they don't need to be replanted every season.

Lavender will bloom in the summer months, producing beautiful purple flowers that attract pollinators.

After blooming, the plant will go dormant, but it will still need water and care to ensure it comes back strong the following year.

Some lavender varieties are more hardy than others, so be sure to choose a variety that is suitable for your climate and growing conditions.

With proper care, a lavender plant can live for many years, providing a beautiful and fragrant addition to your garden.

Lavender Plant Hardiness

Lavender plants can thrive in cold climates, but it's essential to choose the right variety. English lavenders and Lavandin hybrids are the most cold-friendly categories, making them ideal for northern growers.

The USDA Hardiness Zone map helps determine how to care for lavender plants over the winter. Lavender plants are generally hardy to zones 5-9, meaning they can be grown as perennials through the winters for years to come.

To grow lavender in cold climates, it's crucial to be strategic with your herbal tending. In hardiness zones 3 and 4, the softer parts of the plant will partially die back and go dormant while the woody core remains. With proper protection, the herb will re-sprout and continue growing in the spring.

To determine the best lavender varieties for your northern garden, consider the hardiness zone you're located in. This will help you choose varieties that can thrive in your climate.

Lavender plants are generally hardy to zones 5-9, but some varieties can tolerate colder temperatures. For example, English lavenders and Lavandin hybrids are the most cold-friendly categories.

In zones 3 and 4, the softer parts of the plant will partially die back and go dormant while the woody core remains. With proper protection, the herb will re-sprout and continue growing in the spring.

To keep your lavender plants alive in a cold climate, there are a few key secrets to keep in mind.

Here are some popular varieties of English lavender that are well-suited for northern gardens:

  • 'Vera' - an heirloom variety that is also extremely cold hardy (to -20° F, zone 5a)
  • 'Munstead' - a dwarf cultivar that can tolerate hardiness down to zone 3
  • 'Sharon Roberts' - intensely fragrant and reblooming, with thin flower spikes
  • 'Wee One' - the smallest lavender in cultivation at only 10" tall

These varieties can overwinter in zones 5 through 8 and tolerate long periods of drought. In zones 3 and 4, most growers rely on added frost protection or a microclimate area to keep these semi-woody shrubs alive.

For the best results, choose a variety that is specifically bred for cold hardiness and can tolerate the temperatures in your area.

English Lavenders are not ideal for growers in zones 3 and 4, as they require added frost protection or a microclimate area to survive.

In these zones, English Lavenders can't tolerate the harsh winters, making it difficult for them to thrive.

Growers in zones 5 through 8 are in luck, as English Lavenders can overwinter and tolerate long periods of drought in these regions.

However, English Lavenders can grow quite large, reaching up to 3 feet tall and 4 feet wide, making them less suitable for containers, unless you choose a dwarf cultivar like 'Munstead'.

Lavender plants come in a variety of types, each with its own unique characteristics. The most popular types include English, French, Spanish, Woolly, and English hybrids.

English lavender is a classic choice, with long spikes of fragrant flowers that bloom in late spring to early summer. Its silvery leaves remain fragrant even after the flowers have faded.

French lavender has distinctively toothed leaves and long-lasting, subtly fragrant blooms. This variety is particularly resilient and can tolerate humid conditions better than others.

Spanish lavender is a standout in any garden, with its unique pineapple-shaped blooms topped with vivid, purple bracts. It prefers hot, sunny climates and is drought-resistant, making it ideal for low-maintenance landscapes.

Woolly lavender is notable for its silvery foliage and tall, deep purple flowers. It's native to hot and dry hillsides in southern Spain and needs well-drained soil with little to no overhead watering.

The English hybrids, also known as lavandins, come latest in the bloom cycle, starting just as the English lavenders are finishing and continuing to mid summer. They have long gray leaves and grow much larger and faster than English lavender.
