My favorite style of gardening, the one that suits the Appletree Garden, is a solid mix of annuals and perennials with some shrubs thrown in for backbone. Ideally, not a bit of soil or even mulch, in sight.
And my inspiration, I think, came from hiking with my parents in various national parks. One meadow I remember in particular was in Grand Teton National Park, mixed wildflowers two to three feet thick.
If you ever get tired of life, sit for a while in a meadow or garden like this!
