Tansy, also known as "tanacetum vulgare", is a perennial plant with dark green foliage and yellow flowers. It belongs to the Asteraceae family and can reach a height of up to 1 meter. Its leaves are finely cut, which gives it a light and airy appearance.

Tansy is a hardy plant, which grows easily in most well-drained soils. It appreciates sunny locations and also tolerates partial shade. It is recommended to plant tansy in a place where it will benefit from a few hours of sun per day to encourage its flowering.

Regarding the planting period, it is advisable to plant tansy in spring, once the risk of late frosts has passed. It is best to leave a space of around 30 centimeters between each plant to allow the tansy to fully develop. It is also possible to propagate it by dividing the tufts in spring or autumn.

Tansy usually flowers from July to September. Its small yellow flowers in flower heads are grouped in corymbs on strong, erect stems. They attract many pollinating insects, making them a beneficial plant for the garden.
