The Huntington Library, Art Museum, and Botanical Gardens in San Marino, California USA has recently created a unique sign aimed at deterring plant theft. The sign marks the former location of a stolen specimen, references the value of The Huntington’s plant collection, and provides QR codes to online information about The Huntington’s conservation and research programs, and BGCI’s recent statements on plant poaching. We hope this is of value to others facing plant theft!
