At this time of year parsnips are putting up flowering stems and lots of greens. Care is needed when handling these, especially on sunny days. The greens contain a chemical which can cause nasty blisters on the skin if exposed to sunlight (https://en.wikipedia.org/wiki/Parsnip#Toxicity). Wear gloves, and keep your sleeves rolled down. Whatever you do, don’t attack parsnips with a strimmer!
Nasty blisters from sap and sunlight!
