Description
Woolly Creeping Thyme forms a solid very low mat of silver-grey foliage with tiny leaves that are covered in long hairs, which gives the plant its “woolly” appearance and wonderful texture in the garden. Pink flowers come in early spring but this species is not as floriferous as other species. A full sun lover that looks especially nice around stones and boulders in the rock garden or around the garden pond, between stepping stones in paths and walkways, as a groundcover around roses, shrubs, and small trees such as Japanese maples, or as a soil cover and spiller plant in container gardens.
Landscape & Garden Uses
Growing 1 to 2 inches tall and spreading to 18 inches or more over time, Wooly Thyme tolerates foot traffic well so is perfect for use to fill the gaps between stepping stones and pavers or as a groundcover or underplanting for shrubs, roses, perennials and small trees, such as Japanese maples. Very nice around and growing over stones and boulders. Flowering bulbs will pop right through it in spring. Also serves nicely as a soil cover in container gardens. A fine addition to rock gardens and the Xeriscape (low water needs).
Tip: When planting between closely spaced stepping stones or pavers the root ball of some creeping thymes can be divided so as to fit in to the smaller gaps. Just make sure plants have rooted across the soil surface in the pot. If there is only a single stem with branches do not try to divide the plant!
Suggested Spacing: 18 inches apart for mass planting; 6 to 12 inches apart to fill gaps between stepping stones or pavers

Growing Preferences
When planted right and in the right spot, Woolly Thyme is easy to grow. It grows best in light, lightly moist to dry, well-drained soil and full sun. A little shade is okay. Will tolerate rainy periods but constantly soggy soil is a killer. So just make sure to plant in a well-drained site!
