THE NATIONAL ARBORETUM
IN WASHINGTON, DC
http://www.usna.usda.gov
This arboretum was established by
an act of Congress
and is administered
by the U.S. Department of Agriculture,
Agriculture Research Service.
Located in Northeast Washington DC,
consisting of 446 acres, it serves as
an
institution of scientific research
and education. Research is conducted
with cooperative programs in collaboration
with many state universities
throughout
the country.
Many genetically improved crops and
ornamentals
have resulted from these
research programs. These plants with
improved
qualities have been subsequently
patented and released for the consumer
retail market.
Other than research, there are many
excellent
showcase and demonstration
gardens on ornamental, trees, shrubs,
herbs, and bonsai. These gardens are a great resource for all gardeners.
The National Arboretum has
an extensive collection of heirloom roses. These 'old variety roses'
usually bloom in spring. This is a good time to take in the splendor and
exquisite fragrance of these old time roses.
