Pestplanten tromsøsvineblom Jacobaea alpina x subalpina i Norge - opphav og status
Jacobaea alpina (syn. Senecio alpinus, S. cordatus ) and J. subalpina (syn. Senecio subalpinus ) are native to the mountains of Central Europe. Both were cultivated as ornamentals in late 19th century Tromsø. From the early 1990’s onwards, numerous Jacobaea stands have been noticed outside gardens,...
