Tansy is a
perennial plant of the UK, typically found growing in grassland and waste ground, to a mature height of up to 120cm.
Although part of the Daisy family, the composite flowerheads of Tansy do not have long-petalled outer 'ray' florets and are made up entirely of golden 'disc' florets, similar to those found at the centre of the daisy. The appearance of these flowers gives rise to the common name 'Golden Buttons'.
