    Tansy is a tough plant that can grow in almost any sunny spot. While its ferny foliage and clusters of cheerful yellow button flowers are attractive, it can be invasive due to its underground runners and propensity to re-seed.

    Historically, tansy was grown for its medicinal properties, which included treating rheumatism, fevers, sores, intestinal worms, and other digestive problems. It can also be used as an insect repellent. Thomas Jefferson was growing it in his kitchen garden at Monticello.
