Hybrid tea roses are planted more often than all others combined. They produce their classic, large, well formed blooms singly on long straight stems. The plants can be as short as 2 feet, or as tall as 6 feet. Grandifloras are vigorous plants that may reach 10 feet in height. The flowers are very similar to hybrid tea roses, but very large, and with some cultivars, produced in groups.
Miniature roses are less than a foot tall and exhibit fine foliage and very small flowers.
The color range is almost as extensive as that of hybrid tea roses. Climbing roses retain the foliar and floral qualities of the original cultivar, but produce long, vigorous canes that can be trained as vines. The ultimate size depends on the parent plant. Climbing miniature roses, for example do not get very tall. Tree roses, or standards, are actually hybrid teas or floribundas grafted onto a 3-foot stem which has been grafted onto the understock.
