Q.Plant Choices
The front of my house where I have flower beds, they are in shade all winter long, and during the summertime only part of the area gets afternoon sun. The question is, what type of plants should I get for this type of area where part of the bed gets some afternoon sun exposure during the summer but the rest of it is still in the shade? Now, for the back yard I have a flower bed in two different areas. One area gets sun all year long, and the other area where we have this large tree during the winter it’s all sun because the tree loses its leaves but during the summer once the tree has it’s leaves part of the are becomes complete shade and part of it gets morning sun and some afternoon sun. What type of plants should we get for this kind of area since the sun exposure changes? I really appreciate you help in this matter.

You wouldn't need to worry about the winter situation so much because most plants are dormant anyway, plus light is reduced during the winter regardless whether it is full sun. I suggest choosing plants based on the light in summer. Sounds like plants for sun and part sun and plants for shade would work. Also, most plants that need full sun will also do OK in part sun (except veggies). And plants for shade usually do fine with a little sun, too, or dappled shade.
Here are some suggestions.
