You have to be very careful of the stems and the leafs on Parsnip plants, they excrete an oil and when it gets on bare skin and then in the sun can cause a rash and or blisters, so make sure you read about them before planting them.

Thanks for the 'safety' tips for handling parsnips, buddy...Maybe I won't plant them after-all…??? The oil might hurt my cat's tender snout if she sniffs at them.
