"Grandiflora" is a term coined in 1954 to describe a new rose developed from a cross between hybrid tea and floribunda roses. Grandifloras tend to carry their flowers in clusters on top of tall stems. The flower size is a bit larger than floribunda. Grandifloras are one of the taller roses in the modern rose class, so they work well in the back of the border or as a screen. Grandiflora blooms are usually double but lack a striking fragrance. 'Queen Elizabeth' was the very first entry in the grandiflora class.
