Ynghylch

Tansy is an aromatic plant of disturbed ground, rough grasslands, riverbanks and roadside verges. It has fern-like foliage and yellow flower heads that appear in clusters from July to October. It is a composite flower, so the flower heads are made up of lots of tiny flowers called 'disc florets', but no outer 'ray florets'. It has a long history of use for medicinal purposes and was cultivated by the Ancient Greeks. Now, many forms are available as decorative garden varieties, attracting a wide range of insects.

Sut i'w hadnabod

The leaves of Tansy alternate up the length of its reddish stem. Each leaf is divided into many leaflets, which are finely toothed, giving them a fern-like appearance. The yellow flower heads (consisting of lots of tiny flowers) look like small, rounded buttons and cluster together.

Dosbarthiad

Found throughout the UK, but scarcer in the north of Scotland.

Tansy leaves were traditionally eaten at Easter to help kill off the worms that the diet of fish at the time caused. They were quite bitter, so were mixed with eggs, milk and flour in a kind of pancake or omelette.
