it is always pretty easy to spot tansy in an herb garden. my plants happen to be the tallest in my garden with distinctive fern-like leaves. the leaves are bright green with small heads of round button size yellow flowers. this is one of the herbs that will grow in just about any type of soil, and will tolerate very dry conditions. it is very easy to grow by roots and is very easily propagated.
tansy has great insect killing properties and was often hung in kitchens during the colonial days to repel flies. it was also used in sachets to store with clothing during those times. it is said that the leafy foliage will keep cats out of the garden and away from the flower beds.
tansy is a great perennial herb and is grown in my Michigan herb garden each year.
