Additional Information

Plant Biology

Coltsfoot is a perennial herb that grows to around one foot (30 cm) tall. It has flowering stems with purple scales and yellow-gold flowers. One of the plant's most striking features is its heart shaped leaves, which are deep green and smooth on the upper side, but significantly lighter - nearly white - on the other side. The stems are covered by a waxy layer that can easily be removed by hand. Since they usually spread through rhizomes, they are commonly found in the wild, forming colonies of 10 - 20 plants.

    Coltsfoot (Tussilago farfara) belongs to the large Asteraceae family, which comprises about 1,100 genera and 20,000 species, including well-known herbs such as artichoke (Cynara scolymus), dandelion (Taraxacum officinale), lettuce (Lactuca sativa), and marigold (Tagetes erecta).
