Tanacetum vulgare
Common tansy (Tanacetum vulgare) is a fragrant perennial flowering herb native to Europe. It has bright yellow, button-like flowers and long, thin, divided leaves. Common tansy grows in a range of environments, including grasslands, woodlands, roadsides, and disturbed areas. It is easy to grow from seed and can become weedy in some areas. It provides nectar for pollinators, such as butterflies, and can also be used in herbal remedies. Common tansy is known to be invasive in some areas and therefore requires careful monitoring in the garden.

watering
Common tansy should be watered regularly when the soil is dry, about once every 7-10 days. Make sure not to overwater, as this can cause root rot. During the winter months, the plant does not need as much water; once every 2-3 weeks should suffice. In addition, it's important to note that in its natural environment, common tansy prefers moist soil. Therefore, if the plant is planted in a spot that is prone to drying out quickly (like a planter box on a sunny balcony, for example), it is important to water more frequently.
sunlight
Common tansy needs direct sunlight for at least 6 hours per day. It will grow best in full sun but can tolerate partial shade or dappled sun. During the spring, summer, and fall, the sun should be out for at least 6 hours for best results. In the winter it may not be necessary for the plant to have 6 consecutive hours of sun. A few hours of sunlight spread out during the day is acceptable in winter. Common tansy should be placed in a spot that provides direct sunlight for the majority of the day.
pruning
Common tansy should be pruned in early spring, shortly after the last frost and before new growth begins. Prune out the old, dead stems and any weak, damaged or diseased stems. Cut back by about a third, which will help encourage new, healthy growth. Prune main flower stems from well-established plants to ground-level and remove the square remains of last season's flowers. Pruning after flowering stimulates new growth for the following season.
