Rock Creek Park
Named after the Potomac River tributary that snakes through Northwest DC from the Kennedy Center into suburban Maryland, 2,800-acre Rock Creek Park is one of the nation’s finest and largest city parks.

Within city limits, the park boasts 29 miles of foot trails and 13 miles of bridle paths. The creek itself tumbles through six miles of wooded forests, rolling hills and quiet wilderness in the heart of the busy city before fading into the Maryland suburbs.

Washington National Cathedral Gardens
Metro: Woodley Park-Zoo/ Adams Morgan
The Washington National Cathedral's 57 acre-tract provides a perfect view of the city. Located atop the highest point of the city, the grounds of the Cathedral include a variety of gardens.  The Cathedral's small herb garden features rosemary, thyme and mint.  The herb garden also includes Herb Cottage, where visitors can purchase herbs and herb-flavored vinegar.  The Bishop's Garden is the setting for magnolias, orchids and exquisite flowers.  The Little Garden is designed to look like a medieval herb garden surrounded by hedges of old English boxwood. The Cathedral is also home to a rather mysterious treasure, the Glastonbury thorn tree.  This English tree, according to legend, blooms only on Christmas Day and when royalty visits.  The tree has lived up to the legend so far.  It has bloomed only on Christmas Day.  The other five times it bloomed were for Queen Elizabeth's visits in 1951, 1957 and 2007 and for Prince Charles' visits in 1981 and 2005. The Cathedral is also the site of the annual Flower Mart held in early May. 

Woodlawn Plantation Gardens
Overlooking the Potomac River in Mount Vernon, Virginia, Woodlawn Plantation is known primarily for its extensive collection of old-fashioned roses.  Roses were a favorite of the plantation's original owner Nelly Custis Lewis, George Washington's foster daughter.  During a reconstruction of the gardens, the Garden Club of Virginia included two parterres (formal rose bed areas) in honor of Ms. Lewis.  These parterres hold more than 36 beds of roses.  (Phone: 703-780-4000)
