Seattle-based artists Francesca Lohmann and Rob Rhee probe the boundaries between "the natural and the manufactured" with sculptures based on the concept of subspontaneous plant species, which spread through human meddling but continue to flourish without further help. Both artists experiment with unpredictability in their processes, like Lohmann's sprouting potatoes, moldy sausage casings, and liquid plaster sculptures hardened in woven fabric bags and tubes, or Rhee's gourds grown in welded steel receptacles.
