Senecio Jacobaea

These are tricky things. To be kept well away from livestock 🐄

Where we live it is dug out and burnt before the seed sets!

Help me identify this plant

Hi @johnp , welcome. Looks like a nice size plant you have here. Are you able to take a closer picture of the leaves and flower buds coming through? May help in identifying some of the plants finer details. Many thanks in advance!

Ragwort ! Maybe@

More than likely. It is toxic to horses and cattle
