Holly H. Shimizu has served as executive director of the
U.S. Botanic Garden since November 2000. She was introduced to gardening by her grandfather in Rhode Island.
After she graduated from high school in Philadelphia, she was unsure what direction to take. Her mother pointed out that nearby Temple University had an excellent horticultural school and Shimizu enrolled. She received her Associate of Science degree in horticulture and landscape design from Temple, where one of her professors insisted on called her by her botanical name, Ilex (Holly). She went on to earn a Bachelor of Science degree in horticulture from Pennsylvania State University.
She served as assistant executive director and chief horticulturalist of the U.S. Botanic Garden from 1988 to 1996, and then as managing director of the
Lewis Ginter Botanical Garden in Richmond, Virginia, before returning to the U.S. Botanic Garden in 2000 to assume the executive director position.
Shimizu was one of the correspondents, for 12 years, of
The Victory Garden, a gardening show broadcast on public television stations internationally. In addition, she can often be heard on National Public Radio and has written and lectured extensively in her field.
Her husband, Osamu Shimizu, is a garden designer who was botn in Japan. The couple met in England, fell in love in Belgium and married in the United States in 1979. They have a son, Bevan, and a daughter, Alexa.
