Daisies are perennial flowers composed of white petals and a yellow center, explains The Flower Expert. They are propagated by division or by planting seeds in spring or late autumn, and have a growing habit of spreading. Smooth and leafless, daisy stems support a single flower.
Daisies are native to north and central Europe, and the English daisy is a serious weed in the northwest United States. The daisy flower opens at dawn and is a symbol of innocence, purity and new beginnings. There are several varieties of daisies, including the Gerber daisy, Lazy daisy, African daisy, Butter daisy and Giant daisy.
