Clinopodium troodi is a
perennial herb that grows from a woody base (
rootstock). Its
stems trail or rise slightly ( to stems) and measure 2.5–35 cm in length. The stems bear both glandular secretions and fine hairs that range from very short and soft () to longer and spreading (patent-haired), each hair 0.1–0.8 mm long. Leaves sit in opposite pairs and vary from broadly egg-shaped (broadly ) to nearly round with tapered ends (-), about 3–11 mm long and 3–9 mm wide. Each leaf is carried on a small stalk (
petiole 1.5–9 mm long), has smooth edges (entire margins) or shallow, tooth-like notches near the tip (shallowly margins), and is sparsely curled-haired (-haired) with many tiny glands. Flowers are arranged in tight ringed clusters around the stem (), with each ring () bearing 2–10 flowers. Each bloom is enclosed by a two-lipped cup (, sub-bilabiate) 7–10.5 mm long, divided into five small lobes (teeth) and fringed with glandular hairs (). The petals form a two-lipped tube (, bilabiate) 12–21 mm long, coloured yellowish-violet to pale bluish-violet, which sticks well beyond the ; its lower lip is longer than the upper. After flowering it produces four small dry fruits () that are brown and egg-shaped with three flat sides (-), each about 1.8–2 × 0.7–1 mm. ==Subspecies==
