Annual Broomweed, Common Broomweed, Prairie Broomweed

Amphiachyris dracunculoides (DC.) Nutt.

Asteraceae (Sunflower Family)


Annual Broomweed is a warm-season native plant in the Sunflower family. It is an annual that has a single stem growing 15 to 30 inches or 38 to 76 cm tall. The plant branches near the top to form a uniform crown with small yellow flowers in July through November. This growth arrangement distinguishes Annual Broomweed from Perennial Broomweed. The first leaves usually are lance-shaped and form along the main stem, shedding when the crown begins to develop. Older leaves are fine and located alternately along the branch stems. Annual Broomweed provides poor grazing for wildlife and livestock.


The habitat is broad, ranging from dry native ranges to disturbed sites. It is found most typically on heavy clay soils.
