    Patterson Clark harvests D.C.’s invasive vegetation, from which he extracts paper fibers, plant pigments and printing blocks. Those converge at a letterpress to yield prints about the alien weeds. Patterson also produces data visualizations about energy and environmental policy for POLITICO. For several years, he wrote and illustrated the the Washington Post natural history column “Urban Jungle.”
