Scientific profile
Pentaglottis sempervirens is a herbaceous, non-woody plant with broad leaves, reaching a height of around 0.3 m. The leaf area is large, approximately 23,740 mm², and the diaspores weigh about 4.95 mg. It forms arbuscular mycorrhizal associations. Ecologically, it is a warmth-loving species of semi-shade (light indicator 6) and fresh to moderately moist soils (moisture 6). It favours nutrient-rich, alkaline to basic conditions (nutrient indicator 6, reaction 7) and tolerates only slight disturbance (disturbance severity 0.65). Flowering is concentrated in May. The plant is introduced and established in Great Britain, also recorded across much of Europe, and persists in semi-wild habitats.
