This class of rose came into existence when 'Queen Elizabeth' rose was introduced to the market in 1954. In fact, the grandiflora rose class embodies the maiden true blend of the characteristics of hybrid tea rose and floribunda. The grandiflora has inherited the form of the flowers as well as the long cutting stems from its hybrid tea rose parent. Similarly, this class has inherited the hardiness as well as plentiful, clustered blooms from its floribunda parent. In fact, most roses in the grandiflora class, however there are exceptions, are usually taller compared to either the floribundas of hybrid tea roses. Grandifloras are shrubs whose size as well as vigour has varied extensively from one cultivar to another. The floribundas that have been included in this article are the ones that are time-tested and have proved to be exceptional and reliable garden shrubs. Generally, floribundas do well in places where hybrid tea roses also flourish. In other words, it is best to grow this class of roses in the Northwest, Southwest, Mid-Atlantic states and some regions of the Rocky Mountain West, the Northeast and the Midwest where the temperatures during the winter months do not drop below -10�F (-23�C). As far as Canada is concerned, floribundas only flourish in the southeast and the coastal areas of the marine provinces as well as British Columbia. When grown in the Southeast, which has a combination of heat and humidity, grandifloras are generally found to be susceptible to diseases. However, this class of roses ought to be healthier when grown in elevated altitudes in the upper South.
