Mastic thyme
Thymus mastichina

A low, camphor-scented thyme carpeting the hottest, driest ground — living mulch for pollinators and the kitchen. Hates wet feet and fades fast on rich soil.
Mastic thyme in a syntropic line
Mastic thyme belongs in the Ground cover layer as a Secondary productive species. Aim for 2–4 species for resilient, continuous cover. Rough in-row spacing starts around 0.3 m in a syntropic row. Good line partners include Bladder senna, Casuarina. As a Secondary species it carries mid-term yield and structure while climax trees slowly claim the canopy.
