Humphry Marshall’s 300th Birthday Anniversary is a day-long celebration, full of activities where families can learn about Humphry Marshall (1722-1801), America’s preeminent botanists and horticulturist who wrote Arbustrum Americanum, which is recognized as the first botanical treatise written by an American. The special day is sponsored by the Friends of Martin's Tavern with support by West Bradford Township. It's held in Marshallton, PA on the grounds of Martin’s Tavern and the newly created Humphry Marshall Park.


The full day celebration includes outdoor community events, prominent speakers, colonial re-enactors, open hearth cooking and tastings, period music, colonial brews, and children's activities. For kids, there will be colonial games & crafts, and a special native tree propagation program. Saplings grown from these seeds will be part of a tree planting program in township parks. Charlie Zahm is performing early American songs throughout the day as well.

Who was Humphry Marshall?

Humphry Marshall (1722-1801), the namesake of Marshallton, Chester County, was a celebrated botanist and scientist who played a role in America’s transformation from a frontier wilderness to a productive landscape. As a Quaker, Humphry was not active in the American Revolution, but he saw himself as an American and encouraged his fellow colonists to understand and capitalize on the country’s native plants and natural assets. In his lifetime, Marshall was known for his contributions to astronomy, meteorology, agriculture, and natural science. Today, he is best known as the author of Arbustum Americanum (1785), the first publication and catalogue of native plants, shrubs, and trees written by an American and published in America.
