features
The Corsican mint is an evergreen, perennial, herbaceous plant with a pungent odor, which forms lawns and reaches heights of 3 to 12 centimeters with a normally prostrate habit . The above-ground parts of the plant are bald or slightly hairy. It forms aboveground runners. The spreading stems are thread-like.
Both foliage leaves and bracts are petiolate and have simple leaf blades that are 2 to 7 millimeters long, rounded-egg-shaped to elliptical and have entire margins and are buckled at the edge of the blade.
The flowering period extends from June to September. Less than 6 flowers stand together in pseudo whorls . They are individually at nodes. The flowers are five-fold. The five sepals grow together to form a 1 to 1.5 (rarely up to 2.5) millimeter long, top to bell-shaped calyx with triangular-awl calyx tips. The five light lilac petals are fused into a straight corolla tube and an only weakly two-lipped crown.
The fruits are decayed fruits that split into light brown chubs with a smooth surface.
