At the Houston Center for Contemporary Craft, we look at the work of artists Julia Barello and Beverly Penn. Both of them create installations that evoke the plant world: Penn by making bronze castings of real flowers, leaves, stems, branches and seed-pods; Barello by cutting plant-parts out of sheets of exposed x-ray, MRI, and other types of medical-imaging film.
