Thanks for writing. I'm afraid in situations like this there's not a lot you can do. If you try to mirror the sun-loving plants on the shady side of your patio, they'll struggle and look weak compared to their counterparts in the bright light. Likewise, if you try to go with shade-loving varieties in full, hot sun their leaves will likely scorch from the sun and they'll look bad. Your best bet is to go with a design that doesn't depend on being symmetrical --- that way you can have whatever plants you want and they'll look natural.
