Hybrid Ragwort
Jacobaea vulgaris x aquatica = J. x ostenfeldii
(Senecio aquaticus x jacobaea = S. x ostenfeldii)

Family: Asteraceae

Flowering: June-November. Biennial or perennial. Native.

A hybrid between Common Ragwort and Marsh Ragwort. It is intermediate in appearance between the parents and is usually found growing with them. Very variable and less than 15% fertile.

Widespread in Ireland but probably under-recorded as it is easily mistaken for Common Ragwort. Identification confirmed by Paul Green
