Sheep’s-bit scabious is rare and grows sporadically in southern Finland. There are fragmented stands further north, and the northern limit of its habitat is probably Liperi, where there is a feral stand. Sheep’s-bit belongs to the south and has spread to Finland during the Littorina climate, particularly with oak. Plants that are able to thrive at the limit of their habitat like dryish, sunny rock-tops and hills, and it can find a lot of suitable places. Sheep’s-bit does not seem to have exploited human activity in Finland, but in southern Swedish moors it is a common weed on ditch banks and beside highways. It is regionally endangered in Finland.
At first glance flowering sheep’s-bit scabious resembles plants from the Daisy family or devil’s-bit scabious (Succisa pratensis). Even the base of the inflorescence can have one or several whorled scale-like upper leaves – a clear feature of true capitulum. The inflorescence is however umbellate and the individual flower structure is campanulate: the flowers are regular (actinomorphic), the calyx is five-toothed, the corolla is initially tubular and five-lobed, and there are five stamens. The species can be differentiated from genus Campanula plants by the two-leaved gynoecium and the way that the capsule opens along two cracks in the tip.
Shepherd’s Scabious (Jasione Perennis) & Jasione crispa
Jasione laevis & Jasione crispa
World-wide 18 species in genus Jasione are known. A real natural shepherd’s scabious is extremely rare in Finland, introduced during wars and home from Middle-Europe. It looks a lot like sheep’s-bit scabious The first location in Finland was Kuusamo, but the species has been found also from Pirkanmaa. Both scabious species are also ornamentals and seeds can be bought from garden shops. The third scabious, possible in Finland is Jasione crispa but so far it has been happy in gardens and no escapes have been informed.
