I grow an entire wall of basil. Not even exaggerating. It’s an 8’ long row with about 15 plants of different varieties, which get 3-4 feet tall. By the end of summer I’m clipping a whole pound per week just to keep them from flowering. I give away gallons of pesto for thanksgiving and Christmas. If I cared I could probably make legitimately a couple thousand dollars at the farmers market if I wanted to.
