A low woody perennial herb forming a spreading mat of tiny aromatic leaves, with small flowers in early summer. It requires excellent drainage and full sun and will not tolerate soggy soil. Useful as edging or between pavers.

Growing Thyme

Grow Thyme in full sun and low water. Mature plants reach 6 to 12 inches tall and spread 12 to 18 inches wide. Expect low maintenance to keep it looking intentional in a front yard.

In an HOA neighborhood

Thyme takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: front yard, foundation bed, border.

Wildlife value

Flowers offer nectar that generalist visitors will use, but as a non-native it feeds no local caterpillars. Treat it as garden interest rather than habitat.
