Mouse-ear Hawkweed

Pilosella officinarum

Description:

It is a hispid (hairy) perennial plant, with a basal rosette of leaves. The whole plant, with the exception of the flower parts, is covered in glandular hairs, usually whitish, sometimes reddish on the stem. The rosette leaves are entire, acute to blunt, and range from 1–12 centimetres (0.39–4.72 in) long and 0.5–2 centimetres (0.20–0.79 in) broad. Their underside is tomentose (covered with hair). The flowering stem (scape) is generally between 5–50 centimetres (2.0–19.7 in) tall, and sprouts from the centre of the basal rosette. The flowerheads are borne singly on the scape and are a pale lemon-yellow colour, with the outermost ligules having a reddish underside. (Wikipedia)

Habitat:

The plant favours dry, sunny areas. It grows well on sandy and similarly less fertile ground types. It produces stolons are which generate a new rosette at their extremity, each rosette has the possibility of developing into a new clone forming dense mats in open space. It also propagates by seeds. (Wikipedia)

Notes:

The Mouse-ear Hawkweed contains umbelliferone, a compound similar to coumarin and a known antibiotic against brucellosis, as well as a frequent active compound in sunscreen lotions. The plant is also a potent diuretic. (Wikipedia) Synonym: Hieracium pilosella. Greek name: Ιεράκιον το μακρανθές (Π.Γ. Γεννάδιος)
