San Antonio artist hides free ceramic vases along the river in Concepción Park | Daniela Oliver de Portillo

With help from sons Rodrigo, 10, and Emiliano, 8, Daniela Oliver de Portillo prepared to hide three of her art pieces in plain sight in the River Return section of Concepción Park. A gift for whoever finds them, the pieces are part of a larger project — “Hidden Blooms” — commissioned by the San Antonio River Foundation for its “Art In the Open” program. Oliver describes her project as both an interactive art installation and a scavenger hunt. What that means is that anyone who happens upon one of her handmade ceramic vases that holds delicate paper cyanotype flowers is free to take the piece home to enjoy.
