From artist Chrisina Kelly who is working on a project called Maize Field you might have stumbled upon in BK...
"This summer I'm growing blue corn in two areas of Brooklyn as part of a public art project called Maize Field. The gardens are located in Boerum Hill and Canarsie. I hope you'll have a chance to visit them over the course of the growing season.
Each garden is located in an area that was documented as Indian maizeland in the 17th century. They are traditional three sisters gardens (corn, beans and squash) using crop varieties that are part of the heritage of the Lenape and Haudenosaunee from this region. The gardens are a meditation of the change and displacements that have been a part of New York's history. The project participates in the continual change that defines the city by highlighting a historical past then integrating that history back into the present landscape.
You can learn more about the project on my website and follow the gardens on my blog.I hope you'll enjoy watching the corn grow."
