Help! Ragwort said to be very poisonous to horses+cattle. However, Common Ragwort is Senecio Jacobaea and St John's Wort (right) is Hypericum perforatum (both referred to as Ragwort but different species). Are BOTH equally poisonous??? @joshual951 @nervousbotanist @BSBIbotany https://t.co/EFjqvOFxi5
