Wild parsnip and garden parsnip are the same plant.
It's that time of year again, when the fear mongering posts about wild parsnip start going around. It's the exact same plant as the garden parsnip that has been cultivated for thousands of years and doesn't need any extra caution compared to a garden grown parsnip.
This pertains only to Pastinaca Sativa, not Heracleum species that are sometimes called cow parsnips.
Some of the main concerns I hear every year are:
"It looks like hemlock!!" No it doesn't. The leaves are significantly different and look nothing like either carrot or hemlock. The flowers are yellow, not white. The only resemblance to hemlock is that they're tall and green and share a similar form when viewed from a distance. Up close the differences are obvious, and once they flower it's unmistakable.
"They cause photosensitivity and blisters!!" That's true. So do garden variety parsnips, because they're the same thing. Parsnips have been cultivated for thousands of years without people burning all their skin off. How? You harvest them in early spring before the new growth comes up, late fall after the first few frosts, and in the early morning or late evening to avoid the sun. People have been doing this since the Roman empire. Gloves, sleeves and some soap to wash up with have been perfectly fine for millions of people over thousands of years. There is no reason to harvest them when they're in their peak growth season, and at their most dangerous, because they'll be starchy and woody anyway. Your granny was probably doing it this way, are you gonna be more scared of a parsnip than her?
"It can cause blindness!!" Don't get it in your eyes then. If you're not ripping them up like a maniac you're not going to get the sap all over. Don't rub your eyes with your gloves on and you'll be fine.
So where does the fear and misconception come from? It's a crossover from the landscaping/lawncare world. Wild parsnips are a common weed all over the world and often need to be removed when spaces are being cleared. Using lawnmowers, string trimmers, etc on parsnips will aerosolize their sap and completely coat your body in it. this kind of work is also usually done when it's sunny out. This combination makes wild parsnip a serious concern for people clearing brush and weeds where it grows. This isn't a concern you need to have unless you're planning on clearing out patches using machinery. When pulled by hand wearing gloves and long sleeves, the risk of harvesting wild and cultivated parsnips is exactly the same. Use a garden fork to loosen the soil so the root pulls easily and you won't even risk breaking a stem.
I hope this can dispel some of the fear around wild parsnips, because there really isn't any such thing. A parsnip is a parsnip, and any "wild" variety is really a combination of escaped garden varieties and the original native variety. Parsnips have been cultivated for so long that "wild parsnip" is really a misnomer. They've all been affected by human influence.
