The San Antonio Botanical Garden continues its commitment to the arts via its Art in the Garden initiative. By bringing works of art, some permanently and some temporarily, into its confines, the garden is able to add another dimension of aesthetic joy to the experience it provides, and, as a bonus, to invite visitors to look at its botanical collections in fresh ways. Opening Thursday, and on view until February 18, the garden’s latest artistic foray will bring the clay sculptures of local ceramics master Diana Kersey to the Lucile Halsell Conservatory. Kersey’s work, which readers may know from her totem-like, nature-worshipping installation at VIA’s Five Points hub, or one of her other public art contributions around town, is uncannily organic, celebrating natural shapes and the patterns that emerge from the generous chaos of the Earth herself. Kersey, who will bring an array of objects large and small for this installation, is one of the most imaginative potters around, somehow commanding the clay with the playful precision of a brilliant painter.
