My favorite San Francisco garden store, Flora Grubb Gardens, has an installation of a new vertical garden from Woolly Pocket Garden. It’s a modular system for green walls using a simple pocket design. The pockets are a breathable felt made from recycled plastic bottles, and the vertical gardens can be easily installed indoors or outdoors.
And here’s an image of a “green ledge” above a storefront in San Francisco’s Mission District (taken by Leanne Waldal).
