Wild Parsnips
It was likely brought to North America by European settlers, who grew it for its edible root. Since its introduction, wild parsnip has escaped from cultivated gardens and spread across the continent. Wild parsnip roots are edible, but the sap of the plant can cause severe burns.

Collecting the plant from the wild should only be done with extreme care. See the section Protective Clothing below. It typically grows a low, spindly rosette of leaves in the first year while the root develops. In the second year it flowers on a tall stalk and then dies. The plant can form dense stands and spreads quickly in disturbed areas such as abandoned yards, waste dumps, meadows, open fields, roadsides and railway embankments.

Its seeds are easily dispersed by wind and water, and on mowing or other equipment. Like giant hogweed and other members of the carrot family, it produces sap containing chemicals that can cause human skin to react to sunlight, resulting in intense burns, rashes or blisters. It has been reported in all provinces and territories of Canada except Nunavut. The plant is currently found throughout eastern and southern Ontario, and researchers believe it is spreading from east to west across the province. Greenish-white globe-like flower clusters 8 to 25 cm across Leaves: Alternate leaves, divided into 2 to 3 leaflets Stem: Yellowish-green flower clusters 10 to 20 cm across Leaves: Leaves consist of 2 to 5 pairs of leaflets that grow across from each other along the stem, and one diamond-shaped leaflet on the end Leaflets toothed and often shaped like a mitten Stem: White umbrella-shaped flower cluster 10 to 30 cm across, made up of 15 to 30 small clusters Leaves: Leaves have lobes shaped like a hand with fingers, with fuzzy undersides up to 0.
Hollow, 5 cm thick at base Green, few to no purple spots Soft and fuzzy hairs Origin: White flower cluster 5 to 10 cm across. Pale pink before fully opened. Often single purple flower in centre of flower cluster Leaves: Each segment of the lower leaves is further divided into fine lobes, resulting in a feathery appearance Stem: Green, 1 to 2.

Non-native Wild Parsnip Removal and Management If you have small clusters of wild parsnip on your property fewer than plants , you may be able to manage the plant yourself. Wear protective clothing and dispose of plants carefully, as described below. To remove larger infestations thousands of plants , you will likely need a professional exterminator and repeated treatments over several years.
The guide to Best Management Practices for Wild Parsnip describes the most effective and environmentally safe control practices for this species. To manage wild parsnip effectively, learn how to identify the plant in both its first-year stage as a small rosette of leaves, and in its second year, as a tall flowering plant. The area must be monitored for several seasons to ensure complete eradication. Wear protective clothing, including waterproof gloves, long-sleeved shirts, pants and eye protection.
A disposable spray suit over your normal clothing provides the best protection. Spray suits are commercial-grade waterproof coveralls.

After working around the plant, remove your protective clothing carefully to avoid transferring any sap from your clothing onto your skin. Wash your rubber gloves with soap and water, then take off your spray suit or outer clothing. Wash your rubber gloves again and then take them off. Finally, take off your protective eye wear. Put non-disposable clothing in the laundry and wash yourself immediately with soap and water. For a small infestation in a yard or garden fewer than plants , dig out as much of the taproot as you can with a sharp shovel or spade. Digging is most effective in the spring when the soil is moist and the taproot is more easily removed.
Follow-up digging will be required every few weeks to deal with re-growth if the taproot was not completely removed or missed plants. Pulling up the plants is impractical for larger infestations, but mowing can be effective if begun just after peak blooming, but before the seeds set in the late summer or early fall. Cut plants will likely re-sprout after mowing, so it is important to combine mowing with other control methods. Another method of control is to cover the dug or mowed areas with black plastic to smother new growth of all plants.
The plastic should be left in place for at least one season to ensure the roots are smothered. The area must be replanted after the plastic is removed to replace desirable plants and rehabilitate the soil. Contact with the plant, which is found throughout North America, can cause a painful light-sensitve rash similar to that of the Wild Hogweed. Wild parsnip is most irritating while flowering.
When bruised or damaged, Poison ivy, poison oak and poison sumac release an oil called "urushiol" which can cause contact dermatitis, an uncomfortable allergic rash. Most people exposed to the oil will develop an itchy red rash with bumps or blisters.

Severe reactions may require medical attention, according to the CDC. Burning the plants is especially dangerous, as the allergens can irritate the lungs when inhaled.

Poison oak is found primarily in the southeast and west coast. Its leaves have three parts and the plant can take the form of a shrub or vine. The plant may have yellow or green flowers and clusters of greenish or white berries. Poison ivy, perhaps the most notorious of the allergenic plants, is found in nearly every state with the exception of Alaska, Hawaii and California. The plant can be recognized by its three shiny leaves, which can be green or red depending on the season.
Some varieties grow on a climbing vine and the plant may have yellow or green flowers and white, green-yellow or amber berries. Poison sumac is most common near the Mississippi River and boggy areas of the southeast. Each stem on this woody plant has seven to thirteen leaves, arranged in pairs.
