These award-winning varieties have demonstrated superior performance in unbiased trialing tests conducted in widely separated parts of both the United States and Canada. Survival is all-important. And the kinds of plants you grow should be chosen with this in mind. Choosing varieties for a particular purpose or effect is one thing. 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. Do this on a bright, sunny day. As a guide, full sunlight is regarded as 3000 FC or more through the day, with no shade falling on the plants. Partial sunlight indicates shade or dense shadows for a portion of the day, or roughly 1200 to 3000 FC of light. Few flowering or foliage plants will flourish in dense shade, unless they are first grown in sunlight and then moved there when well developed.
