plants for narrow raised bed
We just completed a raised patio and have put a raised be around the perimetre. It is about 20" wide and on one side (facing the neighbours) we would like to put some sort of living wall (bamboo? cedars?) and on the longer section that faces the yard we would like to have something that rises up a bit (1-2 feet) that has season-long interest. Not sure if we want to do one type of plant or a mixture of two or three. We wondered if we should just do an long-blooming annual (impatiens?) that would allow us to experiment a little more - but wondered if anyone had any good perennial suggestions. Has anyone has seen a situation like this and might have some plant suggestions - for both the lower rising front edge and the high-rise green wall at the side.
