There's a plant thief on the loose in Sunnyside, lock up your flowers.

According to the Sunnyside Post, plants in Sunnyside Gardens are unsafe. For the third time since March, a criminal with a green thumb has stolen plants from Terry Murphy, a resident of 47th Street.

The most recent incident occurred Sunday night when a large “Sum and Substance Hosta” was stolen from his front yard…

“It’s a very bizarre kind of thing to steal,” he said.

The plant was apparently not worth more than $25, but this wasn’t the only plant Murphy lost to crime.

In addition to “Hostas,” a small tree was also stolen from his property, according to Murphy, who has moved many of his plants to the backyard.
