Cow parsnip (Heracleum maximum) is a native biennial, often given a bad wrap due to its similar look to invasive giant hogweed and its phototoxic sap (albeit not as severe as hogweed, but can still be harmful). However, they have beautiful flowers, are beloved by many pollinators and is part of our ecosystem. Does great in part shade-full sun and can make a great addition if you have a spot where you dont need to make contact with it! The ones we have at the nursery now are on their second season and starting to produce their flowers for the year!
