I love this tiny thyme! It’s Elfin Creeping Thyme.
It flows over the rocks like water.
Its new leaves are bright green. Some leaves blush to burgundy. Most stay a soothing bluish green.
Its leaves are so tiny, that the clump looks like carpet until you lean in to get a closer look.
The trick to keeping thyme happy is DRAINAGE. They hate sitting in soggy soil
That’s why my thyme gets perched on top of a rock wall.
