Consider that in the northernmost parts of Scandinavia the growing season is 60 days long. The rest of the year is basically a prelude to or recovery from winter. This is all you need to know to understand the local impulse to spend every possible moment living outdoors, wallowing in nature. A picnic table, outdoor tub, and stylish privy will get you through the summer months just fine.
These are not people who take their gardens for granted. Nor do they fuss over them, or try to force nature to assume an artificial symmetry. Self-sowing wildflowers are rampant. Manicured lawns and precisely pruned shrubs, not so much.
For once, I think I am on the ball with my "wild woodland" border. It has self-sown lots of poppies - yellow ones earlier when there was nothing else and now opium poppies that are about four foot high, red, with purple center. Also, ground-hugging "weeds" such as white clover, groundsel and sorrel and borage, to name a few. From early Spring, there has ben a succession of colorful flowers, that came there in mysterious ways!
