We already mentioned the prevalence of the outdoor arena at last weekend's Dwell on Design in LA. But its worth delving into the trend of moving the outdoor world inward. And at Dwell, a few designs making it easy to place plants in non-traditional indoor locations—like a wall—suggest that greenery may be taking the place of more traditional works of art.

About a year ago, we posted about a great Kickstarter project, Urbio. Designers Beau Oyler and Jared Aller surpassed their goal by about $60,000, and the resulting product was in effect at Dwell, as the modular board + magnetic planter systems are now in production and available.

Another take on plants-as-art is local Los Angeles plant and design shop Potted's City Planter. The planters are essentially a sheet of steel, with a rectangular steel pot, hand-finished with a sealed rust patina. The industrial steel combines nicely with the organic matter.

And another interesting rectangular solution for 'planting' vertically indoors was the basic raised-bed-for-your-wall, Shelter Black's Garden State Box. The box is essentially a wood frame, with a wire mesh built in for securing plants. Available for purchase, or just DIY.
