My question is this: I have an under the deck shady area that we can walk upright in. It faces south and gets some pretty good sun-2 hours or more in the late morning on the edges (half the bed). The rest of the bed does not get anything, but what comes through the deck planks. This sun is high noon to mid afternoon. I was planning on shade plants (Hostas that take shade) for this area and some Astilbe (even though they are not low water use). Any other ideas? For the outside one half, I have selected Hosta X Paul's Glory (does best in Light Shade). Can I get by with plants that take more light just because of our intense sun?
