Desert Botanical Gardens, Arnold Arboretum and Endor Community Garden

In Phoenix the temperature can soar above 100 degrees for days on end--an unlikely place for a garden. But at the Desert Botanical Gardens, horticulturists have assembled a world-class desert environment in an area that gets seven inches of rainfall a year. There are plants here that play dead to deter predators and others that defend themselves with thorns and thick wool.

Arnold Arboretum
Boston, Massachusetts

At the Arnold Arboretum history unfolds quietly in the changing of the seasons. On 265 acres a canopy of amazing trees includes dawn redwoods, mimosas and goldenrain trees. Established in 1872, the arboretum was designed to look like a park by famed landscape architect, Frederic Law Olmsted.

Endor Community Garden
Bronx, New York

Through the drive and determination of a neighborhood tired of litter and graffiti, a neglected corner of the Bronx became a garden. The result is Endor Community Garden-- three acres of land returned to life along the Henry Hudson Parkway. Local teenagers and adult volunteers pitch in to keep the garden looking great and to replant the original species that once grew here.
