A piece of blue-green is seen against a light in a jade store and factory in Antigua, Guatemala, on May 22, 2002. Since the 18th century, collectors, geologists and archaeologists have sought the answer to a frustrating mystery: The ancient Olmecs fashioned statues out of this striking blue-green jade, but the stone itself was nowhere to be found in the Americas. Now scientists believe they have discovered the source -- a mother lode of jade in Guatemala.

Greening Your Home

Expect your first harvest within a couple of years of planting the tree.
