description

The kind is a perennial herbaceous plant ( Hemikryptophyt ). It becomes up to 2 m high and has a spreading habit. The leaves are divided into three numbers. When they are young, their pinnate sections are pointed forward at an acute angle, resulting in a broom-like effect. Later they are spread out, up to 10 cm long, 1 to 3 mm wide and pointed.
The umbels are large and have up to 4 bracts (but these often sloping). The flowers are yellow. The fruit is oval, usually 5 mm (up to 10 mm) long, 3 to 5 mm wide and has broad ribs (difficult to see on dried material.)
The number of chromosomes is 2n = 66.
distribution
Location requirements
Peucedanum officinale grows individually or in loose stocks in light-rich, lime-rich, alkaline, moderately dry, but at times somewhat watery places. Natural growth sites are perennial fringes, exposed stands of dry oak forests or little-used, poor meadows. The real hair strand is a character species of the Geranion sanguinei association in Central Europe, but also occurs in alluvial mesobrometes or in the Potentillo albae-Quercion petraeae.
General distribution
The real hair strand occurs in Europe, here scattered from the Iberian Peninsula, over France, Central Europe, to Italy and to the Balkan Peninsula. East to the Black Sea.
Distribution in Germany
Peucedanum officinale is only very scattered and rare in Germany; it occurs only in the middle and south of the area.
