Mexican sunflowers have bright orange (sometimes yellow or red), daisy-like flowers that grow on tall, branching stems with multiple flowers per plant. The leaves are medium green and coarse. They begin blooming mid-summer and don't quit until late fall. They love hot, dry climates and average soil. They attract butterflies (Monarchs love them), bees, hummingbirds, and other beneficial pollinators.
