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.

  • Southern Magnolia

    Southern magnolia, is a stunning evergreen tree native to southeastern United States, and admired for its massive, creamy white flowers that can reach up to 12 inches in diameter. It thrives in hot, humid climates and can even tolerate occasional drought. Its thick, glossy leaves and lemon-scented blooms have made it a beloved symbol of the South. The flowers are so large and fragrant that they’re pollinated by beetles, not bees because magnolias evolved long before bees even existed!
  • Common Milkweed

     A North American native perennial celebrated for its fragrant clusters of pink to mauve flowers and its essential role in supporting wildlife. The plant is the primary host for monarch butterfly caterpillars, whose larvae feed exclusively on milkweed leaves and store the plant's toxic compounds as a defense against predators. In late summer, its distinctive seed pods split open to release silky, windborne seeds, creating a familiar seasonal spectacle. Although once considered a weed of fields and roadsides, common milkweed is now recognized as one of the most important plants for pollinator conservation.
