Senecio spartioides
Also called Broom senecio, Butterweed, Broomweed, Broomlike Ragwort, Broom Groundsel, Many Headed Groundsel
Broom-like ragwort (Senecio spartioides) is a native subshrub of dry, rocky, disturbed ground in the western US and northern Mexico, growing up to about a metre tall. It is a wild species rather than a commonly grown garden plant, and it thrives with sun, good drainage and little water.
Senecio spartioides is a species of flowering plant in the aster family known by the common name broom-like ragwort. It is native to the western United States as far east as the Dakotas, Texas, and northern Mexico. It can be found in dry, rocky, often disturbed areas in various habitat types. It is a subshrub which can exceed a meter in height, its arching stems growing from a woody-topped taproot. The leaves are linear in shape and up to 10 centimeters long. The leaves usually have smooth, unlobed edges, but slightly lobed leaves are seen at times. The leaves are evenly distributed along the stems, the ones low on the stems withering away early, giving the plant a naked appearance on the lower half while the top is still lush green and blooming. The inflorescences are spreading, flat-topped arrays of many cylindrical flower heads.
