• Can be grown as annual: If you don't keep thyme indoors during the winter, treat it like an annual in places that are cold.

Which Thyme Varieties Are Considered Perennial?

A lot of thyme plants come back every year. Some are better for cooking, while others are better for decoration. They all need a lot of sunlight, little water, and good drainage.

• Common thyme (Thymus vulgaris): This is the most popular thyme for cooking. It is also called English thyme.

• German thyme: A type that can survive the winter and has a strong taste.

• French thyme: It's more delicate and is sometimes called summer thyme.

• Lemon thyme (Thymus citriodorus): A bright, citrusy thyme that is used in tea, vegetables, and stews.

• Creeping thyme: A type that grows low and is often used in rock gardens or paths.

Does Thyme Come Back Each Year?

Yes, in USDA zones 5 and above, thyme often returns in early spring with fragrant growth, making it ideal for perennial gardens in temperate climates. Thyme comes back after winter with stronger stems and leaves. Thyme grows well in many areas where it needs little to no help from people. Because it can come back on its own, it's a great plant for a perennial garden or an herb garden.

What Seasonal Changes Does Thyme Go Through?

Thyme grows a lot in the spring and summer, but it slows down in the fall and goes dormant in the winter. It stays green all year in warm areas. In places where it's cold, it may go dormant but come back when it gets warmer.

• Early season: In the spring, new growth appears.

• Peak flavor: It's best to harvest these in the summer when the flowers are blooming.

• Fall prep: Take off the old sprigs and any stems that are woody.

• Winter rest: The plant stays alive while going dormant.

Where Does Thyme Grow Back Best?

Thyme grows best in a sunny spot with dry soil that doesn't stay wet for long and has a little bit of organic matter in it. It doesn't like having wet feet and would rather be in poor soil than rich soil. A rock bed, herb garden, or container would work best.

• Full sun: At least six hours of sun each day.

• Soil: Not very nutrient-rich, dry and loose, and a little sandy.

• Containers: Can be moved inside if necessary.

• Spacing: Make sure each plant has enough space to grow and spread out.

Does Thyme Lose Its Leaves In Winter?

Thyme stays green in most places during the winter, but very cold weather can make it lose some leaves. The roots are still alive and will be able to regrow in the spring, even if they look dry or faded. Garden thyme that stays outside during the winter usually does better if it is cut back in the spring.

Is Thyme Truly Evergreen In All Climates?

In mild climates (zones 6–9), thyme may stay green year-round, but in colder regions it typically loses leaves during winter dormancy. In areas with milder weather, they keep their green shoots even when it's cold. Some leaves fall off in colder winters, but this doesn't hurt the plant in the long term.

• Zones 6–9: The leaves stay fresh and green.

• Zones below 5: Get inside or take cover.

• Evergreen trait: Keeps thyme useful year-round.

• Wind protection: Place close to walls or other things the object can't pass.

What’s the Best Time to Harvest Flavorful Thyme Leaves?

When thyme is growing, it tastes better. The best time to harvest is before or during bloom, which is usually in late spring or early summer. Always trim a little bit to keep the plant from getting too woody and to help it grow more.

• Peak time: Right before flowers show up.

• Avoid over-harvesting: Leave some sprigs and stems.

• Dry sprigs: In a warm room, hang upside down.

• Use in dishes: Great with broccoli, tomatoes, lime, soups, and tea.
