This art piece is called Unity Fountain. The artist, Delia DeLapp, made it with enamel fused to copper in 2006.
Unity Fountain was a gift to the Garden from Jennifer and Jay Ellis in honor of their wedding in the English Garden. Instead of giving party favors, Jen wanted her wedding guests to contribute to the celebration, so she had them write messages on rocks which they left in the fountain. The fountain features two trees intertwined in union, ascending from the Earth in springtime through the sky and up to the heavens, symbolizing Jen and Jay’s eternal love and great bond to each other.
