The majestic sunflower, arguably the most recognized "American" flower, displays a perfect and intricate symmetry that can make you unknowingly stare for minutes at a time. Native Americans were the first to domesticate sunflowers to have a single large blossom and a variety of seed colors. Sunflowers are an excellent food source for bees, and birds literally flock to the seed heads in fall. Look for multi-branching, single flower, and even pollenless varieties. Whichever variety you choose, your garden will be even sunnier for it.
