A bed built around red creeping thyme
The planner designed this bed around red creeping thyme when this page was made: a 12 × 6 ft (3.7 × 1.8 m) English border in zone 6, full sun. It chose the other plants from the 715 that suit those conditions and its dry soil, and says below why red creeping thyme stands where it does.
The plants
- 1 Red creeping thyme × 11, red
- 2 Alpine aster × 5, purple
- 3 Little bluestem 'The Blues' × 8, tan
- 4 Brown-eyed Susan × 3, yellow
- 5 Silver sage × 1, silver leaves
- 6 Butterfly weed × 3, orange
- 7 Ornamental onion 'Purple Sensation' × 4, purple
- 8 Tulip 'Lilac Wonder' × 12, pink
Why this plant
- The only dense clusters. The others are daisies, spires, flat plates and others. Shape reads at a distance, where colours blur.
- The only red.
Why here
- On the front edge. At 2 in it frames the bed without hiding it, and it is in leaf all season. It finishes 47% of the edge.
- 11 plants in 3 runs (5, 3 and 3). Runs of different lengths make the edge a frame, not a ruled line.
- Fine leaf against bold. Silver sage is beside it: the strongest contrast of leaf there is.
Why now
- In flower for six weeks. From early June to mid July.
- Part of the bed's peak. With alpine aster and ornamental onion 'Purple Sensation' in early June: 3 kinds at once. No week has more.
- The only leaves in winter. From November to March it is what there is to look at.
Planned as an English border: 4 of the 6 groups (67%) are drifts, longer along the bed than they are deep. Neither end outweighs the other: the visual weight is split 48 to 52, left to right. Silver sage, red creeping thyme and alpine aster finish the front edge.
The planner's own design check: 12 Excellent, 5 Good. It flags one thing to watch: Nothing on this plan is highly poisonous or an aggressive spreader.

Where red creeping thyme goes in a border
At 2 in it belongs at the front of a bed. In the planner's ten height classes it is ground-hugging (up to 6 in).
Its job: carpet. A groundcover planted in threes and fives to cover the soil: along the front, and just behind it.
The brightest carpet thyme, and the one most often used between stepping stones and as a lawn substitute on dry banks. It takes light foot traffic.
- Between stepping stones
- A flowering lawn substitute
- Dry banks and wall tops
What to plant with red creeping thyme
Plants recorded as good partners for it, and what each pairing does:
- Woolly thyme: its grey-green leaves are a setting for the flowers, before and after; happy in the same dry soil.
- Hens and chicks: its green leaves are a setting for the flowers, before and after; tall enough (4 in) to stand behind it; happy in the same dry soil.
- Blue fescue: its blue-green leaves are a setting for the flowers, before and after; tall enough (10 in) to stand behind it; happy in the same dry soil.
Questions about red creeping thyme
Does red creeping thyme need sun or shade?
Red creeping thyme grows in full sun (6 or more hours of direct sun a day).
It wants dry, sharply drained soil, on the lean side, with no feeding, and little watering once settled. Once settled in, it stands drought.
What zones does red creeping thyme grow in?
USDA zones 4 to 9. It is hardy to zone 4, which means it survives winter nights down to about −20 °F (−29 °C).

When does red creeping thyme flower in my zone?
In zone 5 it flowers early June to mid July. As a summer flower it moves about half a week for every zone: earlier where it is warmer.
| Zone 4 | Mid June to mid July |
|---|---|
| Zone 5 | Early June to mid July |
| Zone 6 | Early June to mid July |
| Zone 7 | Late May to early July |
| Zone 8 | Late May to early July |
| Zone 9 | Late May to late June |
Worked out from Hopkins' bioclimatic law: spring arrives about four days later for each degree of latitude north, and one zone is roughly two degrees. A warm spring or a cold one moves any garden two weeks either way.
How far apart should red creeping thyme be planted?
12 in (30 cm) apart, from the middle of one plant to the middle of the next. That is a little closer than its full width of 18 in (45 cm), so a group knits into one patch.
It grows 2 in (5 cm) tall. Give it the full distance from anything taller, or it will lean out towards the light.
How many red creeping thyme plants do I need?
At 12 in apart, set out in staggered rows:
- 12 to fill 10 square feet (about 1 m²)
- 11 for a single row 10 ft (3 m) long
- 38 to fill a 4 × 8 ft bed on its own
In a mixed border, plant it as threes and fives, along the front and just behind it.
In the bed above, the planner used 11 in three groups.
Is red creeping thyme poisonous to dogs and cats?
No toxicity is recorded for dogs, cats, horses or people, according to NC State Extension.
"Not toxic" is not "edible": a pet that eats a lot of any plant can be sick.
Is there a native plant like red creeping thyme?
Red creeping thyme comes from Greenland, Europe to Turkey. These North American natives come closest to doing its job:
- Three-toothed cinquefoil: the same job in a bed and the same flowering time; 4 in taller, white, not red.
- Woolly yarrow: the same job in a bed and the same flowering time; 6 in taller, yellow, not red.
Matched the way the planner's Swap button matches plants: the same job in a bed, then size, then flowering time.
Do deer eat red creeping thyme?
Mostly not. NC State lists it as resistant to deer and rabbits. No plant is proof against a hungry deer in a hard winter, but this one is low on the menu.
What flowers after red creeping thyme?
Red creeping thyme is over by mid July. These start as it finishes and carry the same spot on, so it never goes flat:
- Lilyturf: from early August to mid September, 16 in tall.
- Black-eyed Susan: from mid July to mid September, 24 in tall.
- Ornamental onion 'Millenium': from mid July to late August, 18 in tall.
What does red creeping thyme look like in winter?
Red creeping thyme keeps its dark green leaves all winter, so it is one of the plants that hold a bed together from November to March, when the perennials have gone.
Is red creeping thyme good for bees and butterflies?
Red creeping thyme is visited by pollinators, bees and butterflies.

Checked against NC State Extension and VASCAN (plants of Canada). Flowering times are for zone 5: later in colder zones, earlier in warmer ones.

Check your local invasive species list before planting anything with a spread warning.
