Distribution of the species
On Mt. Paggaio, it has been observed in a relatively large altitudinal range, and specifically from 300 m asl. (north of the mountain) to almost up to the top. On the SE side of the mountain we can find it at altitudes higher than 900 m asl., reaching almost to the top.
Description of the species (biological and ecological features)
Perennial plant, with branching stems that reach a height of 90 cm, hairy and violet tinged. The leaves, up to 7 cm long, are oblong-elliptical, slightly or strongly heart-shaped at base, with serrated-crenate edges. The leaves have numerous glands, which produce essential oils that protect the plant from herbivores and pathogens. The inflorescences consist of numerous flowers, which can either be bisexual or only female with sterile male reproductive organs. The corolla of the flowers is bicolor, pink to blue, while the “neck” of the flower is sometimes white. It is considered a valuable medicinal plant, with expectorant, diuretic, antiseptic, cough, anti-asthmatic, antioxidant and sedative properties. Current research that could lead to its use as a bio-pesticide, capable of replacing antibiotics and chemical pesticides, is encouraging. It is found in forest openings and grasslands in the mountainous and subalpine zone up to 2,100 m asl. We will see it in flower during the months June and September.
Due to its relatively wide distribution on Mount Paggaio, no particular threats and pressures were observed or reported, which could lead to a significant reduction in its population.
