In the photo above we see another popular style of fence: white picket fences.
Note how the white picket fence in the photo above undulates, rather than running evenly across the top. This undulating style helps soften the hard lines of the clapboard house, in the background.
Despite the fact that this landscape is located downtown, it exudes a charm evocative of a country cottage. The white picket fence is partly responsible, but so are the black-eyed susans peeking out through the pickets. A more formal (and more conventional) planting of annual flowers just wouldn't have the same effect. Another idea would be hollyhocks, which are often used to grace white picket fences in the cottage garden style. But even these or other conventional perennials wouldn't connote "country" as effectively as do these wildflowers.
In the next landscape idea picture we'll look at another example of white picket fences.
