The flowering period extends from May to September. About ten flowers are arranged in clusters of inflorescences . The sepals are 0.2 to 2 millimeters long and prickly.

The fruit is at most as long as the flower envelope.

The number of chromosomes is 2n = 36.

Occurrence

The hairy broken herb is a sub-Mediterranean floral element . Its distribution area extends from the Canary Islands across the Mediterranean to Pakistan , and it is also found in East Africa and South America .

In Central Europe, the hairy broken herb thrives on lime-poor , mostly weakly acidic, humus-poor , rather solidified, stony-sandy soils . It needs plenty of warmth in summer. It settled patchy sandy lawn , sandy roads, embankments and dunes , mostly in the upper and middle Rhine region , in the area of the mouth of the Main , at the foot of the Swiss Jura , the Lake Geneva and the Alpenfuß . In its Central European locations, it is rare to inconsistent. In Central Europe it is a character species of the order Corynephoretalia, but also occurs in societies of the Thero-Airion association or in the Kickxietum.

In Austria the hairy broken herb occurs scattered in the federal states of Vienna, Lower Austria, Burgenland and Upper Austria as well as inconsistently in Styria, in Carinthia, Salzburg, Tyrol and Vorarlberg in the collinen height level . The species is considered endangered in Austria and endangered in the northern foreland of the Alps.
