An innovative vegetable garden

I've been admiring vegetable gardens lately. Mine is looking quite nice enough, but is showing the stresses of drought and (excessive) woodchuck herbivory, not to mention dry weather-induced powdery mildew on (non-predated) squash leaves.

This lovely garden is tucked into a second lot behind a renovated house in Asheville, NC. They've created a studio/shed/office (?) behind their house that frames the vegetable garden.

It's delightfully laid out with green metal edges, and Southerners will appreciated the tobacco plants next to the asparagus.

And isn't this rainbarrel cool, screened by an attractive wall of tumbled stone?
