The classification of the roses has been made by origin, historical development and growth features.
Important grades can be found here in the Rosarium:
ALBA – ROSES
Were already there in Roman culture, are already widespread in the Middle Ages. The origin of the R. alba is unclear; it is not a wild species, but a hybrid, probably a crossbred of R. damasceana x R. canina.
BOURBON – ROSES
They are the result of a coincidence crossing of the 'lie de Bourbon' /France) from R. chinensis x R. damascena.
DAMASCENA –ROSES
They are souvenirs of the crusaders to Europe in the 14th-century. It is probably a crossbred from R. galica and R. phoenicia respectively moschata.
GALLICA – ROSES
They have existed already since the 12th-century, as oldest cultivated rose at the Persians and Medes and in Europe since the 13th-century.
MOOS – ROSES
They are a mutation of R. centifolia. In England in culture since the start of the 18th-century.
MOEYSII – ROSES
Wild form, native of west china, imported to Europe around 1900; many forms and varieties were created.
PIMPINELLIFOLIA – ROSES
An especially large bloom form from the Altai-Mountains (west-Asia) is the crossbred partner for many early blooming Pimpinellifolia-hybrids. In the first half of the 19th-century, over 100 garden varieties were selected from this type in England and Scotland.
RUGOSA ROSES
Were imported from Japan to Europe in 1856. At the end of the 19th-century, they were used in France, Germany and the USA for diverse crossings.
CENTIFOLIAS
They were created in Holland in the 16th-century, probably from a crossing of R. damascena bifera x R. alba. They are also called cabbage roses.
BEDDING ROSES
POLYANTHA ROSES
Created in England in 1865, by cross breeding of the Japanese multi-flowering wild rose R. multiflora with taller roses. This category is named R. polyantha, due to its origin. Its characteristics are: low growth, rich flower, numerous small blossoms in large panicles.
Polyantha hybrids / Floribunda roses
Created Denmark, around 50 years later. They are the next progenies of the Polyantha roses through crossbreeding of large blooming rose varieties.
