Tanacetum vulgare is a perennial, herbaceous flowering plant of the aster family, native to temperate Europe and Asia. ... It is also known as common tansy, bitter buttons, cow bitter, or golden buttons. The Latin word vulgare means "common".
This perennial plant prefers well-drained, fertile garden soil but tolerate almost any soil conditions.
Cut the foliage and flower stems to the ground every year to keep growth in check. Tansy roots go deep so be prepared to do some heavy shovel lifting if you want to remove the plant completely. Your most effective recourse is to dig it out and throw it on your burn pile
