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.

  • Greater Yellow Lady's Slipper

    This orchid was once more common in southeastern Pennsylvania, but has become rare due to habitat loss. Lady’s slipper orchids can be incredibly long-lived; the plants seen here were planted in the Garden in 1963.  The greater yellow lady’s slipper was the first species entered into Longwood’s plant conservation program.
  • Flowering Dogwood

    The bright red berries produced in the fall, are a high-fat food source for over 36 species of birds, including wild turkeys, cardinals, and robins.  The tree supports more than 100 species of moths and butterflies, which lay their eggs on dogwood leaves—making it essential for local food webs. Because it flowers early, it’s also a critical nectar source for pollinators just coming out of winter dormancy. In fact, its ecological value is so high that Cornus florida is often promoted in native plant gardening for habitat restoration.  While the tree is too small for lumber, dogwood wood is incredibly hard and dense. It’s been used historically for golf club heads and handles for tools and knives.
