Martha Stewart says she chose the bonsai as the symbol of a geriatric center that bears her name because of the tree's longevity.

"With the proper care and nurturing, a bonsai tree can live for well over a hundred years," Stewart said in a statement.

A ribbon-cutting ceremony for the Martha Stewart Center for Living at Mount Sinai Medical Center was set to take place today.

Stewart, 66, donated $5 million for the outpatient clinic in Manhattan, which she is dedicating to her 93-year-old mother, Martha Kostyra.

Stewart said she wanted the center, which is expected to open in November, to encourage older patients to "embrace a healthier lifestyle."
