Longwood Gardens at Kennett Sq., Pennsylvania
I have visited this garden about five times. Once at Christmas, and the rest through out the year. The photos in this blog were taken in February 2012 during their annual orchid display. Of course there many other plants, but orchids are my favorite. Fortunately, we were blessed with a springlike day.
Longwood Gardens is so huge, you might need an entire day to see everything. The maps are small, but gives you an indication of how huge the site is.
