A tradition for over 40 years, the William Paca Garden Plant Sale provides the opportunity to take home a piece of history. HA volunteers personally raise over 8,000 plants – perennials, annuals, trees, vines, and vegetable starts – that represent the best of the old and the new. From heirloom tomatoes to Thomas Jefferson’s favorite snail vine, you will find something here to delight. . All proceeds of this beloved annual fundraiser support the programs of the William Paca Garden!
