The Pennsylvania Horticultural Society connects people with horticulture and together we create beautiful, healthy and sustainable communities.
In 1827, the nation's first passenger and freight railroad, the Baltimore & Ohio, was incorporated, slavery was abolished in the state of New York, and on November 24th, a group of gentleman farmers, botanists and other plant enthusiasts held a meeting to create the Pennsylvania Horticultural Society.

PHS produces the Philadelphia Flower Show, the world’s largest and oldest indoor flower show, and operates nationally renowned urban revitalization programs. It also oversees PHS Meadowbrook Farm, a boutique garden center in Abington Township, PA.
