Polish name: common tansy
Latin name: Tanacetum vulgare
Family: the asters Asteraceae (the composites Compositae), subfamily Asteroidae
Status in Poland: native plant or introduced and established in Ancient history
Tall perennial with a strong, not very pleasant camphor smell.
The stems are hard, stiff, alternate foliaged, and quadrangular. It forms imposing, pinnate leaves, with the lower ones usually pinnate-incisure, and the upper ones tooth-incisure.
Contrary to the pyrethrum flowers (chrysanths), to which it is sometimes classified by some botanists, it develops only orange or dark yellow disc flowers, with the calyx reduced to a membranous pappus. The marginal flowers in the head are one-sided truncate, more orange and female only, while the internal flowers are bisexual and lighter. It develops quite characteristic, umbellate inflorescences of the second order (corymbs), made of first order inflorescences (small, flat heads composed of thousands of inconspicuous, disc, single flowers).
The fruit of common tansy is an achene with 5 ribs and 1 seed. Only orthodox-type seeds with TSW 0,2 g. The germination rate for common tansy is typically 26.5-29%.
It is easy to cultivate, prefers light places with light, well-drained soils.
Common tansy is expansive and grows unlimitedly, therefore its development in the garden should be controlled.
As an element of urban flower meadows and bee pastures, it is intended to protect against unwanted arthropods such as mosquitoes and ticks.
As a plant with a strong odor, rich in potent secondary metabolites, tansy was formerly used as a spice (its head-like inflorescences were baked in a dough, and delicate young buds were marinated instead of capers).
It was put in coffins or shrouds were soaked in it so that the corpse would not stink, but it would mummify nicely.
To this day, in permacultures, biodynamic agriculture etc. it is used to produce natural pesticides against ticks, mosquitoes, meal moths, aphids, and the Colorado potato beetle (which is why it was called “insect herb” in many languages).
Like other herbs with a laxative and expectorant effect, it was used for external and internal deworming, against varicose veins, bruises and persistent rheumatic pains. Modern pharmacy still uses tansy preparations for head and genital lice. Research is ongoing to obtain safe anti herpes medications from this herb.
Excellent, a species valued for its long, late flowering, sometimes until the beginning of winter.
In the past, honey hunters used it to incense beehives during their honey picking.
