Winter annual; flowers June to July. Grows one to three feet tall. Leaves alternate, with a coarse, rough texture when touched. Cotyledons (seed leaves) have a dark purple vein. Flower heads narrow and topped with pink, lavender or purple flowers in groups of up to five. Seeds have a distinct ring of dark, stiff, bristles encircling broad end.
Found in range, forest and disturbed non-crop lands. The primary Pacific Northwest habitat is southern slopes in steep canyon grasslands.
Common crupina is a native to the Mediterranean region.  The source and means of crupina's introduction into the U.S. is not known.  The first population was discovered in Idaho in 1969. The plant was spread to northeastern Oregon through contaminated hay.
