Creeping thyme (Thymus serpyllum) is a perennial herb thatâs winter hardy down to USDA zone 4. It has thin, fine-textured, semi-evergreen foliage and small, fragrant, flowers in shades of purple, pink and white, that appear between late spring and early summer.Â
Unlike culinary thyme (Thymus vulgaris) varieties that grow into upright shrub-like shapes, creeping thyme is dense and low-growing with a sprawling vine-like growth-habit that spreads to cover the ground like a soft carpet. It is drought-tolerant and grows best in full-sun locations with well-draining soil.
Creeping thyme can be used as a culinary herb but is better suited to landscaping applications such as ground cover between patio and path stones, rock gardens and rocky slopes or a low-maintenance lawn alternative for full-sun areas that need to handle light foot traffic. Â
As a gardener I’m always curious about the intricate details of the plants I grow, including what the seeds look like. When it comes to thyme the seeds are tiny and mysterious, leaving many wondering – what do thyme seeds actually look like?
In this article, we’ll uncover the appearance, uses, and growing tips for this versatile herb seed.
A Quick Thyme Background
Before jumping into the specifics of thyme seeds, let’s go over some thyme basics. There are over 300 varieties of thyme plants. Some common types include
-
English thyme – the most widely used culinary variety Has a pungent, slightly lemony flavor.
-
French thyme – milder taste better suited for stews and soups than English thyme.
-
Lemon thyme – bright citrusy notes delicious with fish or chicken.
-
Creeping thyme – low-growing with pink or white flowers. Used as fragrant groundcover.
All thyme varieties are in the mint family and originally come from southern Europe. They grow as woody-stemmed, small-leaved perennials reaching 6-12 inches tall. When conditions are right, thyme produces delicate white, pink, or purple flowers loved by bees.
Now that we’ve covered some background, let’s look at the appearance of thyme seeds.
What Do Thyme Seeds Look Like?
Thyme seeds start out enclosed in the plant’s small tubular flowers. Once pollinated, the flowers fade and are replaced by tiny seed pods known as nutlets.
Each nutlet contains 1-4 seeds. Nutlets measure about 1-2mm long. They are oval and turn from green to light brown as they mature.
When fully ripe, nutlets split open, releasing the seeds inside. Thyme seeds are under 1mm in size. Their miniscule dark brown or black bodies make them difficult to see.
Here are some tips for identifying thyme seeds:
-
Look for brown, oval-shaped nutlets. Split them open to find even smaller seeds within.
-
Seeds resemble flakes or specks of black pepper. Use a magnifying glass to examine them closely.
-
Gently crush a mature nutlet between your fingers. The tiny seeds inside will be revealed.
Now you know that those black specks you see on your thyme plant in late summer aren’t dirt – they’re seeds!
Harvesting and Storing Thyme Seeds
Want to collect your own thyme seeds? Here are some tips:
-
Allow thyme plants to flower and set seed in the garden. Don’t harvest any leaves once flowers appear.
-
Watch for nutlets to turn brown and split open when mature.
-
Pick nutlets by hand and place them in a paper bag or envelope. Air dry for 1-2 weeks.
-
To remove seeds, rub nutlets between your fingers over a bowl. Pick out any remaining plant debris.
-
Store seeds in an airtight container in a cool, dark place. They remain viable for 2-3 years.
Proper harvesting and storage keeps your thyme seeds fresh until you’re ready to plant them.
Growing Thyme from Seeds
Adding more thyme plants from seed is simple. Thyme seeds require light and a warm environment to germinate. Follow these tips:
-
Start seeds indoors 6-8 weeks before your last spring frost date.
-
Sow seeds shallowly in sterile potting mix. Cover lightly with soil.
-
Maintain soil temperature of 70°F. Bottom heat speeds germination.
-
Keep seeds moist but not soggy. Mist to prevent drying out.
-
Seedlings emerge in 14-21 days. Transplant outdoors after last frost.
-
Space plants 10-12 inches apart in full sun and well-drained soil.
With proper care, you’ll enjoy tiny seedlings that mature into bountiful thyme plants.
If sowing directly outside, wait until after last frost when soil has warmed. Prepare seedbed in full sun, rake smooth, sow seeds, cover lightly with soil, tamp down, and water gently. Thin seedlings to proper spacing.
Extra Tips for Growing Thyme from Seeds
Here are a few additional pointers to help successfully grow thyme from seed:
-
Take care not to overwater. Thyme prefers drier conditions.
-
Clip plants back halfway in early summer to encourage bushy new growth.
-
Thyme grown from seed often has better flavor than nursery transplants.
-
Choose upright growing varieties if you plan to harvest frequently. The stems are easier to access.
-
Allow some flowers and seeds to develop each year. This ensures an ongoing supply of seeds.
Enjoying Your Homegrown Thyme
A little patience and care yields wonderful rewards when growing thyme from seed. Soon you’ll have plenty of fragrant leaves for seasoning dishes.
Here are some ways to use homegrown thyme:
-
Add fresh or dried leaves while cooking soups, meats, vegetables, and more.
-
Make bundles of fresh thyme sprigs to add great flavor to stocks.
-
Infuse olive oil or vinegar with thyme. Perfect for marinades and dressings.
-
Craft aromatic thyme soaps, sachets, and potpourri.

Brew tea from fresh or dried thyme leaves and flowers for a soothing beverage.
Now that you know what thyme seeds look like, it’s time to start planting and enjoy this versatile herb fresh from your garden.
How to Transplant Creeping Thyme Seedlings Outdoors
Plan to transplant your creeping thyme seedlings outside anytime after the last frost date for your area has passed. Before transplanting, be sure to harden them off for a week or two by gradually exposing them to full sun and wind to avoid transplant shock.Â
Red or White Creeping Thyme
âMost creeping thymes bloom purple. But, if you want either a more subtle or a more vibrant look to your creeping thyme while it is in bloom you can also find varieties that bloom white or red (more accurately described as a bright fuchsia-pink).
âA dense, low-growing, thyme variety with lavender blooms and a unique pale silvery-green fuzzy foliage. A great choice if you want to add some contrasting ever-gray foliage to your garden.
