Astrantia maxima, (largest masterwort[3]), is a species of flowering plant in the family Apiaceae.

The cauline (borne on the stem as opposed to basal) leaves are generally two, sessile, amplexicaul and lanceolate-shaped with a trilobed apex.

The floral bracts are numerous (10 - 20), 10–18 millimetres (0.39–0.71 in) long, pinkish (sometimes white) with acuminate apex.

This perennial plant reproduces itself also by means of buds present at the ground level.

The seeds require a 2-3 month period of cold stratification for germination to take place.

[8] In Turkey, they are common in woodlands and lush meadows, at an altitude of 1,300–2,400 metres (4,300–7,900 ft) above sea level.

Its flowerheads provide summer colour in shades of red, pink and white.
