Have you ever seen those aerial photographs of managed landscapes and not managed landscapes adjacent to each other? They're meant to startle through the visualization of untenable differentiation. Not to minimize that, but this spot where the front yard meets the side yard has the qualities of those photos. Nothing, not even these dayflower weeds, will grow beyond this line. Its as if they know that that spot belongs to my landlord and just won't take the chance! He's a killer, a mad man they think. Do not cross that man. Don't even try it!
By the way, I am developing a notion that folks think vegetable gardening, as opposed to flower gardening, is a trashy activity. Why? All variables taken into consideration, people seem to dump more trash in my vegetable growing side yard. Is it because it speaks of work over beauty? Both sidewalks are residential and active. But the front yard always has flowers and the side yard pots with vegetables. Is it the weedy look of tomatoes? I suppose I'll never know, but it don't matter. Next year, I'm back to perennials over in the side yard with a handful of herbs because only those you need close at hand.
