Colorado four o'clock is a perennial desert wildflower native to the southwestern United States and northern Mexico, grown for its magenta, funnel-shaped flowers that open in late afternoon. It needs full sun, very good drainage and little water, and it dies back to the ground in winter or drought and regrows from its root.
