Gardeners in Maine have told me this flower is a real pain. It’s a perennial that’s hard to get rid of if it’s in your yard.
Originally from Eurasia, Tansy (Tanacetum vulgare) looks like a daisy without any white petals. It was brought to North America as a medicinal herb but it grows too well in Maine’s coastal climate.
I often see it by the side of the road and wonder … where are the white petals?
