ANN ARBOR, Mich. — A pair of University of Michigan researchers are putting the “pee” in peony.

Rather, they’re putting pee ON peonies.

Environmental engineering professors Nancy Love and Krista Wigginton are regular visitors to the Ann Arbor school’s Nichols Arboretum, where they have been applying urine-based fertilizer to the heirloom peony beds ahead of the flowers’ annual spring bloom.

It’s all part of an effort to educate the public about their research showing that applying fertilizer derived from nutrient-rich urine could have environmental and economic benefits.
