Hundreds of the University of Michigan’s iconic peonies were reportedly cut in an act of vandalism – apparently perpetrated by at least one unidentified pro-Palestinian agitator.

The Ann Arbor school’s W.E. Upjohn Peony Garden, located in Nichols Arboretum, is home to North America’s largest collection of historic herbaceous peonies, according to The Associated Press – and it boasts about 800 plants with 10,000 flowers at peak bloom.

However, about 250 – or one-third of them – were found Sunday morning with most of their flowers cut off.

UMich is no stranger to acts of vandalism by anti-Israel agitators – university President Santa Ono’s home and the surrounding area were spray-painted with the words “intifada” and “coward” in October.

The Upjohn Garden incident also transpired on the same day as an alleged terrorist attack on a pro-Israel demonstration in Boulder, Colorado, that left multiple people injured.

The suspect, Mohamad Sabry Soliman, “stated that he wanted to kill all Zionist people,” according to a federal complaint.

The DPSS is actively investigating the matter, which the school describes as a “criminal incident.”

A Public Affairs representative for the university declined to comment further on the incident when reached by Fox News Digital.
