Nick Grillo immigrated to Connecticut from Italy. In Southington he worked as a laborer in a greenhouse and in 1915, set up his own greenhouse in the Milldale portion of Southington. In 1938, Grillo developed the Thornless Beauty—the first hybrid tea rose without thorns. He patented the Grillodale rose in 1923 and in 1931 the American Pride Rose.
