She says Posy Floral Design in Manhattan substituted pastel pink and green hydrangeas for the dark rust and green ones she had specified for 22 centerpieces.
"The use of predominantly pastel centerpieces had a significant impact on the look of the room and was entirely inconsistent with the vision the plaintiffs had bargained for," Glatt, a lawyer, said in the lawsuit, filed on behalf of herself, her husband, David, and her mother-in-law, Tobi Glatt, who paid for the flowers.
The flowers cost $27,000 (€19,000). The lawsuit asks for more than $400,000 (€281,000) in restitution and damages.
Stamos Arakas, the florist, said that he and his wife, Paula, tried to match the color of the hydrangeas with a picture Glatt had given them, but explained to her that the colors might not look the same.
"My father used to tell me, 'Don't deal with the lawyers," Arakas said. "Maybe he was right, God bless his soul."
The choice of the city of Helsinki is not incidental as the capital of Finland had hosted US-Soviet negotiations on the limitation of nuclear stockpiles in 1969
