Rose (Rosa species) plant types are available in an abundance of options. Varieties differ based on the size of the blossoms, the habit and height of the plant and the time of development. Whether you are looking for smaller roses appropriate for indoor use or very large blooms for visual impact in the garden, rose plants produce flowers in nearly every color of the spectrum.
The modern rose category includes all roses created after the year 1867. Modern roses include hybrid tea roses, grandifloras and floribundas. Hybrid tea roses, introduced in 1867, are the most widely used roses in gardening; with an aesthetically graceful quality, these rose plant types display pointed buds, vibrant flower color in all hues of the spectrum, excluding blue and black, and grow on long green stems. Hybrid tea roses reach up to 8 feet in height, according to the Clemson University Extension. Grandiflora rose plant types yield large blooms and also have pointed buds; blossoms grow in clusters, and this plant takes on a shrub-like appearance. Floribunda roses are medium in size but great in abundance; in a wide variety of color options, this plant type is considered a shrub. Less popular but also included in the modern rose group is the miniature rose. Miniature roses grow from 8 to 24 inches in height and display all plant parts proportionally smaller than their larger relatives. Miniature rose plant types are ideal for indoor growth in containers.
The old rose plant type consists of all roses developed before 1867, according to the Clemson University Extension. Old roses are prized for their sturdiness, fragrance and color. European and Chinese roses add a historic and cultural interest to this group. European old roses bloom during the spring and include purple, red, pink and white in their color options. European roses are gallicas, albas, damasks, moss roses and centifolias. Gallicas are upright shrub plant types, damasks are tall and arching with gray-green foliage, albas are tall shrub roses that reach up to 8 feet in height, moss roses are covered in a moss-like substance that smells like balsam and centifolias, also referred to as cabbage roses, are covered in thorns and grow in a bush form that grows to a height of 4 to 5 feet. Chinese roses include China roses, bourbon roses, noisette roses, tea roses and hybrid perpetuals. China roses display semi-double blooms, bourbon roses produce highly fragrant flowers on a shrub type plant, noisettes are tall shrubs with pastel-hued blooms, tea roses are repeat-bloomers with pale blooms and a scent reminiscent of tea and hybrid perpetuals are large bushes with fragrant flowers.
Climbing roses are plant types known for their vigor that ascend the structure they are grown upon, like trellises or buildings. Climbers include ramblers and large-flowered climbers. Ramblers display clustered, small flowers that bloom during late spring; ramblers may spread up to 20 feet within a season. Large-flowered climbers do not grow as quickly as ramblers but display large blooms and need consistent pruning, according to the Clemson University Extension.
