Patterson Clark shared his harvesting and art making processes at the Annual Meeting of the Audubon Naturalist Society last week at Woodend Sanctuary in Chevy Chase, Maryland.
I admire his dedication and inventiveness. Take a look at his brilliant art made of weed pulp paper and essence of weed ink, plus a ferocious amount of creative energy.
In my own quest to help native plants, I usually pull Lonicera japonica out of the trees or bushes it is choking and weave the vines into baskets.
