Grandiflora Roses: What Are They and How to Care for Them

Developed in 1954, Grandiflora Roses are a cross between a Floribunda and a Hybrid Tea Rose, gaining the long stems and fragrance of Tea Roses, with Floribunda-style clusters of flowers on the ends of each branch.

Grandifloras are tall, vigorous Roses that produce very large blooms, and grow in clusters or 'trusses', rather than single blooms. Due to their gorgeous nature, the blooms are traditionally used in cut flower arrangements because Grandiflora Roses are consistent rebloomers that grow to various shapes and heights and are available in a wide range of colors!
