It's built around the compass and each quadrant is based on a color. I may have the colors wrong and will edit after the gardener corrects me.
White, yellow, red, purple/blue. A lovely tree is in the center and a ring of rocks defines the edge. I have to admit that being Princess Practical, when I first saw the design as it's going in I thought "you can't put a garden under a tree!" That thought was immediately followed by "says who?" The 2nd thought was the correct one. You can put a garden wherever you want.
Here it is with the rocks and a few baby plants.
And here it is this morning. You can see the added mulch of wood shavings which looks great. It has a substrate of cardboard and paper. I'm stealing the idea for the area around my camper I think.
A bit of the "yellow" quadrant featuring a calendula plant. I've never gotten calendula to grow at all so I'm impressed.
A bit of the white quadrant
Red quadrant (poorly centered)
More lovely plants. I like the mix. Mostly herbs and whatnot with decorative grasses.
Bit of art near the center.
It's really lovely. I find it fascinating that a mullein, with yellow flowers, planted itself in the yellow quadrant.
The garden follows most of the principles I just read about in Sepp Holzer's book on permaculture. Trees, rocks, mulch, microclimates. This tiny garden has it all going on.
