Tanacetum vulgare


plant overview
pretty but poisonous

Tansy is a perennial plant in the sunflower family that is native to Europe and Asia and features button-like, yellow flowers and feathery foliage. Because of the appearance of the flower heads and the bitter taste of the leaves, the herb is also known as Golden Buttons and Cow Bitter. Although this herb was commonly used as a flavoring agent during the Middle Ages, the risk of toxicity from ingesting certain compounds in the plant, namely thujone, marks this botanical as one not to be ingested. The herb is, however, when used with caution, an effective deterrent to pests, especially fleas and mice.

A Bit of Botany
a little botanical information about tansy

Tanacetum vulgare is a perennial, herbaceous flowering plant of the Asteraceae family.

The plant's erect stem is stout and somewhat reddish. It is usually smooth, growing 50–150 cm in height, and branching near the top.

Tansy features finely divided compound leaves 10-15 cm in length. The leaves are alternate, and are pinnately lobed. They are divided almost to the center into about seven pairs of segments (lobes), which are again divided into smaller lobes with saw-toothed edges. This gives the leaf an almost fernlike appearance.

The yellow flower heads are produced in terminal clusters from mid-to-late summer. The blooms are yellow, roundish, flat-topped, and button-like. The scent is similar to that of camphor with hints of rosemary.

common names & nomenclature
The common name tansy is derived from the Old French tanesie (13th century, Modern French tanaisie), from Latin tanacetum which means "wormwood," from a shortened form of Greek athanasia which means "immortality”.

Also known as:
golden buttons, cow bitter, tansy, common tansy, bitter buttons, mugwort

Cultivation & Harvesting
considerations for growing and harvesting tansy

Tansy is a common plant of waste ground, hedgerows, and herb gardens. It grows in full sun.

Will succeed in any typical garden soil.

Tansy is an invasive aggressive grower; therefore the plant's garden location should be chosen with this in mind. Division is very simple at almost any time in the growing season, though spring is probably best. Tansy can also grow via seed— it should be sown in spring in a greenhouse and grow on until large enough to pot up individually. Plant out the following summer in the garden.

Tansy is harvested as it is coming into flower and is dried for later use.

Store dried tansy in an airtight container in a cool, dry place.

Thoroughly research before growing and harvesting. Care should be taken when handling the plant. There are also toxic warnings on ingestion. Not for consumption!
