Classification of Rose
Roses are broadly classified under two groups:
i) Old Garden roses or Wild roses
ii) Modem Garden Roses
i) Old Garden Roses:
i) Old garden roses includes the crosses between:
a) European Roses x wild roses- and
b) Asian or China roses x wild roses
European roses are having tendency to produce the bloom only once in a year i.e. during summer while Asian or China roses are having habit to produce the flowers throughout the year or at least twice in a year. Due to the development modem roses old garden roses have become out dated.
ii) Modern Garden Roses:
Modern garden roses are developed as a result between the crosses of European Roses x Asian Roses (China roses) and have occupied the place in Commercial gardening. Modem garden roses includes: a) Hybrid Tea (H.T.) b)Floribunda c) Miniature (d)Polyantha (e) Ramblers (f) Creepers (g)Shrub
a) Hybrid Tea:
It is resulted from die crosses between Hybrid Perpetuals x Tea roses of China;
A variety of plant which bears double well shaped flower on erect stem in single. Due to its attractive colours, numerous varieties and fragrance, producing blooms on long canes, elongated buds, slow opening of buds different shapes and size of flowers, good keeping quality widi single, double, multi colour and stripped vars. Hybrid Tea has occupied the important and prestigeans position in the rose garden.
The first modem rose i.e. Hybrid Tea La-France was developed by Guillot in 1867, in France by crossing Hy Perpetuals x China Tea Rose e.g. John F. Keneddy, Gladiator, Superstar, Papa Meilland, First prize.
The first yellow pernet rose was developed by another French rose Breeder Pemet – Drucher by crossing Hy. Perpetual with Rosa lutea "(Rosa foetida) commonly known as Pernet rose’. The first Hy.Tea yellow rose was named as ‘Seleil door*.
It has been produced as a result of crosses between Hy. Tea x Polyantha.
Floribunda produce the flowers in cluster Df better shape and bigger size but the flowers are smaller than H-tea. in Floribunda also different colours, shapes and sizes of flowers are available. These roses witfi their large clusters of flowers given a splash of colours for long season.
The first Floribunda ‘ Rod h a tie’ was developed by crossing Hy. Tea x Dwarf Polyantha by a Danish Breeder Poulson in 1912. e.g. Baojaran, Iceberg, Red gold, Queen Elizabeth, Sea pearl.
These are also called as ‘Baby roses’. They are neat and compact but dwarf plants reaching to a height less than 12 inches and producing small or miniature flowers. They have long blooming period and least affected by cold weather and diseases. These are most ideally suited for edging, pots, rockeries and window gardens e.g. Red flush, pixie, Baby masquarade, Baby goldstar, Cri-cri.
They are dwarf type with small flowers in Jarge clusters, free flowering and perpetual bearing habit. The first polyantfia rose was produced as a result of cross between Rosa multi flora x a variety named Dwarf Pink China e.g. Echo, Flamboyent, Snow princess.
Ramblers required support to climb up and are suitable for covering-fences, walls and trellis. They are vigorous growing with small flowers in .clusters. The flowers are produced only in one flush during the year but it lasts for several weeks e.g. American pillar. Excelsa, Dorothy.
They are stiffer stem and generally have bigger size flowers. They produce the multi-petaled flowers in single on a stem like Hy. Tea or in cluster as iloribunda. The climbers are most suitable for arches, pergola, pillars e.g. Golden showers, Royal, gold, Delhi white pears.
These are perpetual flowering roses taller than bush type but shorter than climbers and provide continuous flowering. Suitable for hedge and shrubbery e.g. Fountain, Cock tail, Butterfly wings.
