The Ohio State University is warning that some poisonous plants could be found in Ohio.
The post on the website for the Buckeye Yard and Garden onLine warns about the dangers of poison hemlock and wild parsnip.
It takes both plants two years to produce seeds.
Both weeds can be identified by their short flower stalks rising from a common point like the ribs on an umbrella.
According to the post, some wild parsnip plants could top 6-feet while poison hemlock could reach a height of 10-feet.
All parts of the poison hemlock are dangerous but the plant’s roots are the most poisonous.
“The toxins must be ingested or enter through the eyes or nasal passages to induce poisoning; they do not cause skin rashes or blistering,” according to the article written by assistant professor Joe Boggs and commercial horticulture educator Erik Draper.
However, wild parsnip has sap that can lead to blisters and skin discoloration.
Wild parsnip and poison hemlock commonly grow near each other but neither is native to Ohio.
