It is ruderal plant, i.e. growing in weed places, namely, waste lands, embankments, ravines, ditches, sides of roads, etc.; it prefers humid places and loam.

The species belongs to the Asteraceae family.


In Latin, tussis means cough and ago from the verb agere means I push outside (in one of its many meaning, since agere is more or less the equivalent of to do). This reflects a common use of the plant and it was probably brought in North America by early settlers for medicinal reasons.

As for the species name, plenty of references say: “The specific name of the plant is derived from Farfarus, an ancient name of the White Poplar, the leaves of which present some resemblance in form and color to those of this plant.” But in the most classical of the Latin to French dictionary, the Dictionnaire Illustré Latin Français by Félix Gaffiot, at the entry farfarus, Mr. Gaffiot cites the word as used by Pliny the Elder (23-79) in his Naturalis Historia, book 24, paragraph 35, and by Plautus (c. 254-184 BC) in the line 478 of his comedy Poenulus; he then translates it as tussilage, one of the French names of Tussilago. So, choose whichever explanation you like, (and I prefer the second one and I don't have the time, in order to settle the matter, to check what Mr. Gaffiot said).

Blooms first appear in early spring and continue into mid spring; it is quite often the first plant to bloom; in my area, 25 km North of Montréal, I have seen a few in bloom at the end of March (on a slope, facing south) and there was still plenty of snow just around; the last snow banks had not yet melted. Flower heads have even been known to push through snow.


Tussilago farfara is a perennial herb which spreads mainly through underground rhizomes. During the summer, food is stored in the rhizomes for the following year's early spring growth. The plant has no main stem.


Flower heads



Frequently on alkaline clays, in roadsides, trail sides, fields wasteland, often as a pioneer. The plant prefer damp soils and full sunlight.

Flower buds and young flowers, raw or cooked, are edible. With a pleasant aniseed flavour they add a distinctive aromatic flavour to salads. Young leaves, raw or cooked, are also edible. They can be used in salads, added to soups, or cooked as a vegetable. The leaves have a bitter taste unless they are washed after being boiled. An aromatic tea is made from the fresh or dried leaves and flowers. It is said to have a liquorice-like flavour. The dried and burnt leaves are used as a salt substitute. The slender rootstock can be candied in sugar syrup.

Tussilago farfara has a long history of medicinal use, mainly as a treatment for respiratory ailments such as coughs, hoarseness, and bronchitis. It is also used as a poultice (fresh mashed leaves) for difficult to heal sores.

Both the flowers and leaves are used, but these parts are harvested separately due to the staggered appearance of flowers and leaves. Modern herbalists either prepare an infusion (like tea) or a syrup that is taken orally for respiratory problems. However, most herbalists are moving away from the use of Tussilago farfara due to recent findings that it contains highly carcinogenic pyrrolizidine alkaloids.
