Rosa polyantha - Wikipedia, the free encyclopedia

Polyantha literally: many-flowering roses, from the Greek "poly" (many) and "anthos" (flower). It is a group of modern garden roses originally derived from crosses between two species of East Asia (Rosa chinensis and Rosa multiflora), the polyanthas first appeared in France in the 19th century along with the tea hybrids.

These first polyanthas featured small, compact shrubs, others of an extended habit, with small flowers (2.5 cm or 1 inch in diameter) presented in large bouquets, in typical white, pink and red colors.

Its fame and main demand was for its prolific flowering: From spring to autumn, a healthy polyantha shrub is literally covered with flowers, creating a strong impact of color in the landscape. Polyantha roses are still considered low-maintenance, disease-resistant garden roses, and they are still popular for that reason.

Pink polyantha was described in 1843 by the German botanists Philipp Franz von Siebold and Joseph Gerhard Zuccarini a rose specimen from East Asia. But it turned out that the Swedish botanist Carl Peter Thunberg in 1784 had already described the same rose as Rosa multiflora .

The first varieties of hybrids of polyantha roses were introduced by Guillot in 1875 'Ma Paquerette' and introduced five years later 'Mignonette'.

Characteristics of Polyantha roses are the umbela inflorescences or also in large clusters of flowers and a very dense growth. They are usually unscented, although here too there are some good scented varieties (eg 'Natalie Nypels')

At the beginning of the 20th century the Polyantha hybrids are formed from breeding roses, which develop a strong color effect with slightly larger, usually semi-double flowers. They are often planted to increase the color effect of distance in groups. on varieties of simple flowers and double varieties.

When crossing with hybrid of tea and other roses silvetres arise types of a variety of intermediate forms, altogether arose the group of Floribunda roses. The Polyantha are very similar to the Rosales Floribunda.

They are compact, very thick shrubs, laden with small flowers. Bouquets composed generally of 7 to 15 small flowers, pentapétalas, simple or double.

They bloom in summer to autumn. They are planted in groups and to make borders generally of a single variety by mass, to obtain a mass effect of color. Good use in branches.
