Tansy Mustard is a particularly hardy annual found in disturbed, barren sites with bad soil. It is hairy, heavily branched and can vary in appearance, growing .5 to 2’ tall as either a clumping thicket or tall and erect. The tips of the stem branches are covered with yellow flowers that are made up of four petals. It blooms for about two months starting in April or May. It reproduces only from seed and can be toxic to grazing animals. Commonly found along railroads and prefers full sun.
