For better or worse, this has become a shade garden, at least parts that border a strip of forest along the southern edge of the property, in front, and along the northern border where dozens of trees I’ve planted over three decades have grown in. This leaves only an area in the center of the rear garden where there’s a spot of sun, which is mostly occupied by the large koi pond. Otherwise, only a few small areas receive any more than a few hours of direct sun. And, it’s not so bad. In fact, I think I might prefer the shade rather than a sun baked garden.
Certainly, there are limitations. Finding enough soil to plant in between maple roots can be a challenge, but an aggressive wood spurge (Euphorbia robbiae) has spread through the worst of the driest shade, and hostas and ferns have managed to make the rest of it look presentable without too much effort on my part.
In shade, flowers are a bit more limited, but then the gardener must learn to appreciate varying textures and shades of green. Which, I do.
