How to Select Fragrant Ground Cover
Fragrant ground cover can give off an aromatic scent when its leaves are lightly crushed underfoot or brushed against at the edge of a border, or it can offer fragrant flowers in garden beds and borders. Ground cover plants spread over bare soil, shading out weeds and providing a visual link between plants or different areas of the garden. Select plants that best fit the intended purpose, such as low-growing varieties with fragrant leaves for spaces between stepping stones or at border edges or long-blooming cultivars to provide scent over the growing season.
Stepping on ground cover growing on or near garden footpaths is unavoidable. Select low-growing ground cover with tough, aromatic stems and leaves for these areas.
'Magic Carpet' creeping thyme (Thymus serpyllum 'Magic Carpet') withstands light foot traffic when the plants are established. Hardy in U.S. Department of Agriculture plant hardiness zones 3 through 10, 'Magic Carpet' grows 1 to 2 inches tall and 12 to 15 inches wide and offer magenta-pink blooms late spring through summer. Its leaves are silver-green and emit a lemony fragrance.
Chamomile (Chamaemelum nobile) also tolerates a little foot traffic. Chamomile foliage is finely dissected and fernlike, and when it's bruised it gives off a fruity aroma. Yellow-centered, white daisylike flowers appear summer through fall. Growing 3 to 6 inches tall and 6 to 12 inches wide, chamomile is hardy in USDA zones 4 through 9. Select this plant if you'd like to create a small, flowering lawnlike area that won't be stepped on frequently.
To provide reliable, long-lasting fragrance in your garden, grow ground cover that features scented blooms over the growing season.

'Chewground' and 'Montrose White' are hardy in USDA zones 5 through 9.
