The downtown St. Paul empty lot at Robert and 10th Streets, which is supposed to eventually become the city’s newest park — Pedro Park —  will again have a temporary incarnation this summer as the Urban Flower Field.

The project, by Public Art St. Paul, kicks off Saturday with a look at the intersection of science and art.

Like last year, artists and scientists will transform the space with flowers and art and projects to remediate the soil.

The opening ceremony will be from 10 a.m. to noon Saturday; organizers say visitors “can paint fieldstones to place along the art-filled paths, enjoy a glass of lemonade and talk with the artists and scientists behind the project.”

The space was donated to the city by the Pedro family, which ran a luggage (not furniture, as I said earlier) store there for years, but that was in 2009, and other than the flower field, there’s not been much action on the park project.
