We spotted Michael Hellgren's green designs at the Stockholm Design Week. This less usual landscape architect designs vertical gardens, or better walls, made out of plants.

Växtväggen (Swedish for "Plantwall") is a self-supporting system composed of a reinforced, multi-layered, synthetic and absorbent felt-surface on which plants are applied into small pockets. Michael says: "Just like any garden, the vertical garden is a place of life and change. I try to achieve it by finding the essence of every plant - it could be a special color of its leafs, its texture, the way it growths etc - and give each species an environment where this may be at display."

His work with these living materials seem to blend with all kinds of places - so keep your eyes open for plant wall sightings. Apart from his interior applications we love this urban approach where contrasting plant walls enrich the public spaces of us city slickers.
