I'm always rooting for the grass and flowers that push their way up through the cracks of the sidewalk, but I've never thought of creating a cement garden by intentionally growing plants and flowers in the cracks. Luckily somebody did...
CMG Landscape Architects did a project between two buildings that involved creating cracks in the existing cement foundation and planting flowers, vegetables and herbs. The result is quite extraordinary.
This is a really unique way to beautify an otherwise plain and boring urban cement patch. I think it's a great alternative to digging up an entire concrete patio to make room for a garden. Your urban garden oasis is just a jackhammer away.
