Agastache scrophulariifolia, also known as the purple giant hyssop, is a perennial plant that grows throughout the US and Northern Ontario, CN. Its name comes from the similarity of its leaves to plants of the genus Scrophularia. It is a beneficial plant to pollinators and is noted for its medicinal properties, as many plants in the mint family are. It tends to grow in disturbed or open areas where it does not have to interact with non-native competitive plants.
