Grandiflora roses are crosses between hybrid tea roses and floribunda roses. Blooms have the impressive size, classic form and extensive colour range of hybrid tea roses, but are usually borne in clusters of three to five blooms. They will provide a long season of colour, blooming from early through late summer.
Plants are usually large and dense, creating quite a commanding presence in the landscape. Grandiflora roses are especially striking in the back border, or as a friendly fence along a property line. They can also be used as accents on the end of a border, or as specimen plants in the perennial garden. Clusters make sensational bouquets for indoor enjoyment.
Grandiflora roses are a cross between floribunda and hybrid tea roses. Most varieties produce large classic blooms, though some varieties of grandiflora rose produce old-fashioned very double flowers. Blossoms appear in clusters of three to five, creating intense bunches of red, purple, gold - grandifloras are available in a rainbow of colors. Some varieties reach heights of 5 feet. Our grandifloras perform well in hardiness zones 4 to 10. They tolerate a variety of soil conditions, including clay, loamy or sandy. Individual cultivars have differing light requirements, but most prefer half to full sun. Be sure to check individual varieties for planting and care instructions.
