If you're ever in San Francisco, you should make it your beeswax to check out the plant shop Flora Grubb.
Why? The most jaw-droppingly novel arrangements of plants I've ever seen. I recently made the trip out to Bayview (which also contains one-third of San Francisco's toxic waste) to explore the garden. To my delight, Flora Grubb has plants growing out of bicycles, sinks, and cars, and a "vertical garden" out of which colorful succulents sprout.
Some eye candy:
More of a crafter than a gardener myself, it inspired and reminded me to think of plants not just a means of nutrition, but as living entities that can be used in unexpected ways to beautify spaces and objects.
