They are usually small, violet-blue or purple in color and appear in glomeruli, groups of three per leaf axil. corolla It is long and exceeds the size of the calyx, being aromatic and attracting numerous pollinators like bees.
Su natural habitat It includes shady and humid forests, roadsides, hedgerows, fertile meadows, and forest edges, demonstrating great adaptability. Although it prefers moist, organic-rich soils, it can grow in a wide range of environmental conditions, from shady to sunny areas.
Ecology, habitat and dispersion
Glechoma hederacea behaves like hemicryptophyte species; that is, its replacement buds remain on the soil surface, allowing it to survive unfavorable seasons. It has a wide cold resistance, supporting light frosts and very low temperatures. It tolerates moderate drought although it thrives best with regular moisture. In addition, its dispersal is mainly carried out by myrmecochoria (dispersion by ants) and, to a lesser extent, by human action and wind.
It is part of scionitrophilous plant communities of perennial grasses, often found on forest edges and meadow margins, growing on fresh, loose, and nutrient-rich substrates. Its presence indicates fertile, slightly alkaline soils (pH 5.5–8), with good moisture and low salinity levels.
Flowering takes place from March to June and, after pollination, produces small seeds that can be dispersed over moderate distances. Its colonizing capacity is reinforced by the production of stolons which allow the formation of extensive colonies.
