This is an expensive and delicate operation, usually done by hand. Hybrids continue to increase in importance, giving us many of our finest varieties-notably in ageratums, geraniums, marigolds, pansies, petunias, snapdragons, sultanas, wax begonias, and zinnias. They can be counted on for vigor and uniformity of color, size, and growth habit. And F, hybrids nearly always outclass standard inbred varieties in the abundance of blooms produced. These award-winning varieties have demonstrated superior performance in unbiased trialing tests conducted in widely separated parts of both the United States and Canada.

But you must also consider such important environmental factors as light. Plants obviously require light to grow. And the amount of light you have in different spots in your garden determines the kinds of plants to select for them.
