Longwood Gardens, one of America’s quintessential landscapes, is a place of ever-changing seasonal beauty, handcrafted feats of horticultural wonder, and an awe-inspiring collection of the most beautiful plants from around the globe. 

From our humble beginnings as a Quaker farmstead and arboretum, to Pierre S. du Pont’s forward-thinking stewardship, to today’s collection of renowned landscape designers, horticulturists, and architects, our great garden of the world evolves and emerges again and again.

Through Longwood Gardens and its program of outstanding horticultural display, every visitor to the Gardens has the opportunity to gain, culturally and spiritually, a better peace of mind.

  • Chrysanthemum Festival 2026

    Chrysanthemum Festival fills our historic conservatories with color and artistry October 16–November 15, 2026. In the Exhibition Hall, a vibrant mum curtain provides a backdrop for tiered pagodas and living viewing stones, chrysanthemums trained into shapes inspired by natural rock formations and landscapes. These imaginative displays are just the beginning: explore the many chrysanthemum varieties, colors, and forms throughout the conservatories, from spirals and cascading baskets to clouds and towering columns. 

  • Sugar Maple

    The sugar maple (Acer saccharum) a majestic tree native to eastern North America, bursts into brilliant shades of red, orange, and gold each fall, making it a seasonal showstopper. Its sap is used to make maple syrup, and its dense wood is valued for furniture and flooring. In forests, it supports biodiversity by providing food and shelter for birds, insects, and mammals, while its deep roots help prevent soil erosion.
