A flower at the New York Public Library reportedly died just days after the Rolling Stones rocker allegedly lit up a cigarette and used the plant's pot as an ashtray.
Richards, 66, had been at the library's Cullman Center for Scholars and Writers on October 29 for a talk about his new memoir, Life.
And before he went onstage it is claimed he had a cigarette in the office of deputy director Marie d'Origny. She said he opened the window as he smoked.
But the orchid - a Phalaenopsis amabilis - apparently couldn't take the smoke and the draught from the open window, and its 12 white flowers fell off four days later, the New York Daily News reports.
A representative for the musician was unavailable for comment.
