Quotations
Many countries still refuse to recognize “grandiflora” as a legitimate name, largely on the ground that it seems to imply that the individual blooms are unusually large, whereas most grandifloras have somewhat smaller blooms than the larger hybrid teas.

✓ Climbing sports: These climbers — generally named after their original variety, such as ‘Climbing Queen Elizabeth’ from the famous, pink grandiflora — result from unusually vigorous canes that grow from popular hybrid teas, grandifloras, shrubs, and floribundas.

Our grandiflora stands 7 ft. tall on thornless stems, adorned with massive clusters of fragrant, 4-in., clear pink blossoms whose ruffled edges are tinged with a darker pink. Without a doubt, ‘Queen Elizabeth’ deserves to be the reigning monarch of grandifloras. Grandifloras blend well with other perennials and shrubs.
