Have you thought about adding the tansy flower, also known as Tanacetum vulgare, to your garden? This plant has been used for many years for both health and practical reasons. It's key to know the good and the bad about tansy before using it in your garden. What sets tansy apart, and how can gardeners use it safely?
Introduction to the Tansy Flower
Tanacetum vulgare, also known as the common tansy or bitter buttons, is a perennial plant. It can grow up to 5 feet tall. This plant has reddish-brown stems and leaves that look like ferns.
The leaves are deeply lobed and green. The plant's flowers are bright yellow and shaped like buttons. They grow in flat clusters at the stem ends. When you crush the leaves or flowers, they give off a strong smell.
The name "tansy" comes from the Greek word "athanasia," meaning "immortality." This is because the dried flowers last a long time. Originally from Europe and Asia, it was brought to North America in the 1600s for its beauty and healing uses.
Since then, tansy has spread quickly and is now seen as a weed in many places. It grows fast and spreads through seeds and underground stems. This makes it a problem in the Midwestern and Northwestern United States.

Growing and Caring for the Tansy Flower
Growing the tansy flower (Tanacetum vulgare) is easy because it does well in many conditions. This perennial herb grows 1-5 feet tall, with fern-like leaves and yellow flowers. Let's look at the key things you need to know to grow and care for this garden plant.
Tansy likes full sun but can handle some shade. It grows in USDA Zones 3-8, but may need winter protection in cold areas. When planting, pick a spot with well-draining, rich soil and a pH of 4.8-7.5. Adding compost to the soil helps with nutrients. Plant tansy 12-18 inches apart to let them spread.
Tansy doesn't need much water. New plants need about 1-2 inches of water a week in the first season. After that, it's quite tough and only needs water every 1-2 months, depending on the weather. Too much water can cause root rot, so watch the soil carefully.
This plant is easy to care for. Remove dead flowers to stop them from spreading and encourage more blooms. In early spring, cut it back to the ground for a neat look. But be careful when pruning because the plant can irritate some people's skin.
To keep the plant in check, divide tansy clumps in the fall. This stops it from getting too big and makes the plant healthier. With these tips, you can easily add the beautiful and fragrant tansy flower to your garden.
Tansy Flower Uses and Benefits
The bright yellow flowers of tansy brighten up the garden from mid-summer to fall. Its fern-like leaves add an interesting texture. Tansy is great for cut flower arrangements, can be dried for decor, and draws in bees, butterflies, and hummingbirds.
As a tansy companion planting, it keeps pests like aphids, spider mites, and ants away. A 2001 study by Chiasson et al. found its essential oils can be natural insecticides.
Tansy has been used for medicinal uses but many of these uses are now seen as unsafe because of its thujone content. In the past, it was used for digestive issues, worms, and other ailments. A 1999 study by Williams et al. showed its anti-inflammatory effects, hinting at its potential as a herbal remedy.
Some herbalists still use tansy on the skin for skin issues, bug bites, and muscle pain. But, taking it inside should only be done with a doctor's advice. Its bug-fighting properties also make it a natural pest repellent.
Tansy is considered a weed in many US states. Yet, in the right garden, its tansy garden benefits can be valuable. Knowing its uses and risks is key to making the most of it.
Potential Risks and Cautions with Tansy Flower
The tansy flower (Tanacetum vulgare) has many benefits but also some safety risks. It has a compound called thujone that is toxic if eaten in large amounts. Eating tansy can cause serious stomach problems, seizures, and even death. This makes it very dangerous for pregnant women, as it can cause abortions.
Handling the tansy plant can also irritate the skin and cause allergic reactions in some people. So, be careful when growing and working with tansy, especially around kids and pets. Never eat it without a doctor's advice.
Tansy is also very invasive. It spreads quickly by seed and underground roots, taking over gardens and pushing out other plants. In many places, tansy is seen as a noxious weed that needs controlling. To stop it from becoming a problem, remove the flowers before they seed and consider keeping it in containers. Pulling or digging up the plant works well, but make sure to get all the roots to prevent it from coming back.
