Question: Which now-classic holiday plant made its American public debut at the very first Philadelphia Flower Show in 1829?

Answer: The poinsettia, recently brought from Mexico, was introduced at the one-day show held June 6, 1829, in the Masonic Hall on Chestnut Street. That show was the first public flower show in America, put on by the Pennsylvania Horticultural Society just two years after its founding.
