Growing Non-GMO Tansy Flower Seeds

When growing tansy plants from seed, starting indoors and transplanting is often ideal. Sow 3 to 4 seeds in small pots or seedling starters about 8 weeks before the last frost. After the frost danger has passed, harden off the seedlings and transplant to your garden. Be careful with allowing this plant to go to seed, since it will spread aggressively. Growing in containers can also help prevent uncontrolled rhizome (root) spreading.

Tansy flowers bloom in the mid-to-late summer with yellow button flowers and last throughout the season. As a low-maintenance perennial, it doesn’t require deadheading or pruning, but doing so may help it produce more blooms and keep it under control. Tansy is drought and deer tolerant.

Tansy in the Flower Garden

Tansy is often used as a border for flower gardens. Since it is drought tolerant, it thrives on garden edges. It also protects the other flowers by repelling insects, mice, deer, and other pests that can cause considerable damage. Tansy also has a scent from the flowers and leaves; this scent is often described as being like camphor or rosemary.

Companion Planting with Tansy

Tansy is primarily used to protect other plants from pests. It can be planted as a border around flower beds and vegetable gardens as an effective shield, or used as a ground cover nearby. Its ability to repel mosquitoes makes it an excellent choice to plant along with other flowers to make outdoor spaces more liveable. Additionally, it attracts beneficial pollinators such as butterflies and hummingbirds!

About Tansy Garden Seeds

Tansy contains a compound called thujone, which is a powerful chemical that can cause skin irritation if the leaves are touched with bare hands. It is also unsafe to ingest (Not Edible) and can cause stomach irritation or worse in humans. Tansy is toxic to pets and other animals.

Tansy blooms are small, usually less than 1 inch in size.

Tansy is often used for companion planting with squash, berries, roses, and other garden plants to protect them from insects. The flowers and leaves are sometimes dried to repel mosquitoes for longer or as an accent in floral arrangements.

While tansy originated in Europe and Asia, it was brought to North America and quickly became widespread, even invasive. Tansy can now be found throughout the United States.

⚠️Prohibited States:⚠️

Tansy eagerly spreads via rhizome root spreading. This makes it hard to control much like morning glory and ivy. Leaving even a small portion of roots behind will allow the plant to continue growing. It is illegal to grow in specific states as it can outcompete native plants, degrade pastures, and impede reforestation efforts. Before purchasing this seed it is important to check if growing tansy is prohibited in your state. If so, Black-eyed Susan is recommended as a good substitute.

It is illegal or prohibited to grow Tansy in many central and north western parts of the U.S. where it is considered a noxious weed, including Arizona, Colorado, Idaho, Minnesota, Montana, Oregon, Washington, and Wyoming. It is also considered noxious through parts of Alberta, British Columbia, and Nova Scotia provinces of Canada.

Tansy is considered invasive in many other areas of the United States. Below is a map representing the areas where it has been reported as invasive.

Tips From Our Gardeners

"While tansy is a beautiful and useful plant, it can be very invasive! I’d recommend starting with one or two plants and managing its spread till it fills out your desired area. It will be a lot easier to cut back one big plant instead of pulling out many small plants!"
