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.

  • Smooth Aster

    ‘Bluebird’ is a native aster selection from Mt. Cuba Center that offers violet-blue flowers in abundance on 3-foot stems.  Asters are late blooming perennials that attract pollinators and bring color to the garden in autumn.  Discover other native species of asters in bloom throughout the outdoor gardens!
