Stanley Mehr, 94, who operated a flower business in McLean for more than 60 years, died Jan. 14 at his home in McLean. He had a brain tumor, a niece, Cynthia Young, said.

In 1951, Mr. Mehr and his brother, Seymour Mehr, bought a plot of land in then-rural McLean to grow flowers. In spite of proliferating development and Seymour’s death in 1957, Mehr Brothers Flowers continues to operate in McLean.

For many years, Mr. Mehr also worked for the U.S. Department of Agriculture’s Soil Conservation Service, advising farmers on erosion control and on growing soybeans. He retired from the USDA in the 1970s.

Stanley Mehr was born in New York City and graduated from the University of Wisconsin in the late 1930s. Because Mr. Mehr had raised pigeons as a boy, he served in an Army unit that used pigeons to relay messages in World War II. He came to Washington after the war.

Mr. Mehr’s niece said he spoke several languages and liked to greet customers in their native tongues. He wrote a column about flowers for a community newspaper.

His wife of 65 years, Maria Mehr, died in 2010.

Survivors include a daughter, Julie Mehr of McLean, and two sisters, Rosalind Krupp of Maplewood, N.J., and Rhoda Young of Springfield.
