Tanacetum

Tanacetum is a genus of about 150 species in the family Asteraceae, native to many regions of the Northern Hemisphere.
They can be annuals, perennials or sub-shrubs, with feathery aromatic leaves and daisy-like or button-like flowers on woody stems. Some species have yellow disk florets and no ray florets, while others have both ray and disk florets, usually in yellow or white. The most popular species is Tanacetum vulgare, commonly known as Tansy.

Name meaning

The genus name is derived from an altered form of the Greek word “athanasia”, which means “immortality”, in reference to the long-lasting flowers or to its use as an embalming herb.

Tanacetum symbolism

Tanacetum symbolizes protection, health, resistance and immortality.

Its stability and resistance was expressed in the following poem by Arthur Ketchum:
„When by the roadsides in the sun
I see the tansy’s gold and green,
I know that there in other days
Hearthstone and love and life have been.
There is no need of other sign
To mark the years of labor spent;
For all the dream, for all the hope,
The tansy stands as monument.”
