Known for its feathery, fern-like leaves and clusters of small, bright yellow button-like flowers, Tansy can grow up to 4 feet tall and spreads via rhizomes.

This plant has a long history of use in traditional medicine and as a natural insect repellent. It is also appreciated for its ornamental qualities, adding vibrant color and texture to gardens.

Temperature

Tansy is hardy in USDA zones 3-9. It can withstand a wide range of temperatures, making it adaptable to various climates.

Soil

This plant prefers well-drained, sandy or loamy soil with a pH of 6.0 to 7.5. Avoid heavy clay soils that retain water, as they can lead to root rot.
