Warning: Parsnip Sap

Nasty blisters from sap and sunlight!

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!
