It is grooved, hairy, and, except at the nodes, hollow. The stalk is sparsely branched. Over the winter above ground wild parsnip plants die back with only one or two leaves remaining on each plant. First year wild parsnip growth. Close-up of wild parsnip leaves. Each wild parsnip plant produces hundreds of small yellow flowers which bloom from June to mid-July.
The flowers are arranged in a loose compound umbel a structure made up of a number of short flower stalks which spread from a common point, looking like the ribs of an umbrella. An umbel can measure from four to eight inches 10 — 20 cm in diameter.

The flowers consist of five yellow petals curled inward, five stamens , and one pistil. Seeds mature by early July. Plants die after producing seeds; the dead stalk will remain standing through the winter. Seeds can remain viable in the soil for four years.

Wild parsnip invades and modifies disturbed open habitats. Well-established fields and meadows are not likely to be invaded, but parsnip can become well-established along the edges and in disturbed areas.
Once an infestation begins, it can spread into adjacent areas and form dense stands in high-quality fields and meadows. Wild parsnip is also very persistent on sites that remain disturbed or bare such as paths, roadsides, and utility rights-of-way.

While wild Parsnip roots are edible, the plant produces a compound in its leaves, stems, flowers and fruits that causes intense, localized burning, rash, severe blistering, and discoloration on contact with the skin on sunny days. This condition, known as phytophotodermatitis, is caused by furanocoumarin contained in the sap.
Affected areas can remain discolored and sensitive to sunlight for up to two years, similar to but not as severe as contact with giant hogweed. This reaction is not brought on by contact with the foliage of the plant, only by contact with the sap. Contact may occur when working, hiking, and harvesting crops, including when visiting u-pick operations. To reduce the risk of exposure to wild parsnip sap, when undertaking such pursuits one should wear long-sleeved shirts, gloves and long pants.
If one should come in contact with wild parsnip sap, you should immediately cover the exposed skin to prevent the reaction to sunlight but the area will remain sensitized for about eight hours.

The contact area should be washed with warm water and a mild soap. If exposure to sunlight causes a burn and blisters to develop the affected area should be covered with a cool, damp cloth to help relieve pain. The blistered skin should be kept out of the sunlight to avoid further burning. If blistering is severe, see a physician.

There is no cure for parsnip burns; however, a topical or systemic cortisone steroid may relieve discomfort. Andrew Link, Lacrosse Tribune The essential oil of parsnip roots contains a large percentage of Myristicine, a strong human hallucinogen. Remove new infestations while they are still small. Avoid mowing areas with wild parsnip when viable seeds are present as equipment readily spreads seed to new areas. Clean mowing equipment before moving from an area with wild parsnip to one without. Time control efforts to prevent spread of the plant.
Management decisions should be based on the quality of the area, the degree of the infestation, and use of the infested area by people or livestock. It's in the second season that the familiar yellow flowers appear on the tall stems.
Species Profiles
Wild parsnip flowers resemble Queen Anne's lace, in shape. And it turns out that's no coincidence. Schmalz explains that many plants in the parsnip family contain furocoumarins, chemicals that when combined with skin and ultraviolet light can cause what's known as a phytophotodermatitis. A wild parsnip plant growing in Monkton. Schmalz explains that the wild parsnip's second season is when the yellow flowers appear and the stem can be between four and six feet tall.
But unlike reactions to poison ivy or poison oak, Schmalz explains, brushing up against wild parsnip won't generally cause a problem. And then on top of that, in order for the reaction to complete, you typically need to have some kind of reaction occurring as a result of ultraviolet light contacting that sap on your skin.
That kind of interaction can happen if you pick the plant by hand or are weed whacking and get pieces of the plant on your exposed skin and if that skin is then exposed to sunlight. So people should take precautions when working with these plants.
Wear gloves, safety glasses, long sleeves and boots. Pick a cloudy day to handle the plant, if you can. And if you do get the sap on your skin, the Vermont Department of Health recommends washing the sap off immediately and then wearing clothes that prevent exposure to the sun for another 48 hours.

To manage poison parsnip on your property, Schmalz says you can mow the plant or use herbicides, though he cautions that you should mow before the flowers have gone to seed. If you see the flowers setting seed, bag them up so the seeds don't get into the soil.
