    Tansy is an extremely hardy perennial with a strong smelling scent that acts as a natural insect repellant. Historically it was used to keep vermin and pests (lice, flies, fleas) out of homes and storage areas.

    It was introduced from Europe and grows in most of the US. It's a nice background plant, growing in clumps about 3 feet high. It has feathery, dark green narrow, lance shaped leaves growing alternately along the stem. At the top of the stem the blooms appear in clusters of small, button-like, yellow flowerheads. They bloom from July to October.

    Tansy grows wild all over my property here in Eastern Washington. A little bit more than I would like sometimes, but I've learned to live with it. It's pretty when it's blooming, but I don't care for the smell of it.

    Tansy (Tanacetum vulgare) has value to the garden as a companion plant, reportedly attracting ladybugs, lacewings, parasitic mini-wasps, and tachinid flies, and helping to repel Japanese beetles, striped cucumber beetle, squash bugs, ants, and flies. It has a long history of use as a medicinal herb and as an insect repellant. Unfortunately, Tansy is an aggressive seeder that has become invasive in many areas.
