For the last 40 years the Dutch have been at the forefront of very interesting pubic natural planting designs.
I came across this municipal area on the site of a busy road in front of some apartments near Narden Bussom just outside Amsterdam.
The key elements are large swathes of single species planting linked together with other swathes of differently coloured and textured plants.
Perhaps it is a little too bright and tacky on the eye but cycling past this every day would give you a lift.
The benefits of this style is that it gives the eye a place to relax into and it creates ribbons of movement that give a musicality to a landscape, working especially well in an urban setting.
Also it is very low maintenance!
