Description
A fairy tale floribunda rose with beautiful, freely positioned nostalgic flowers of dark red colour, gathered in small clusters. Her flowers, despite being thin and silky, showed excellent hardiness to unfavorable weather conditions. Moreover, when the flower fades, they fall off cleanly from the plant so there is no need for deadheading. Forms very compact, bushy, slightly spreading plant with attractive medium green glossy leaves. Blooms in flushes throughout the season.
DESCRIPTION OF THE NEW VARIETY
The following is a description of ‘KORcasima’, as observed in its growth in August, 2008 in a nursery in Jackson County, Oreg. on plants of three years of age. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2015 except where common terms of color are used.

Name origin
This rose is a part of the 'Kordes Fairy Tale Rose' collection and pays homage to one the most popular and known European fairy tales about a young girl and a sly wolf, the origins of the tail can be traced back to several pre-17th century European folk tales.

Parentage
ORIGIN OF THE VARIETY
The objective of the hybridization was to create a new and distinct rose plant with unique qualities, such as:
-
Compact and uniform growth and flowering when grown as a plant from cuttings;
-
Abundant attractive, recurrent flowers;
-
Attractive and abundant foliage; and
-
Resistance to diseases encountered in landscapes and gardens.
This combination of qualities is not present in prior rose cultivars. These objectives have been substantially achieved and in that distinguish ‘KORcasima’ from all other varieties.
BACKGROUND OF THE VARIETY
The ‘KORcasima’ variety originated from a controlled crossing in a breeding program of two distinct parents during the summer of 2002. The crossing was between an ‘un-named seedling’ and ‘Insel Mainau’ by Reimer Kordes, 1959.
As part of a rose development program, Wilhelm Kordes germinated seeds from the aforementioned hybridization and conducted evaluations and observations on the resulting seedlings in a controlled environment in Offenseth-Sparrieshoop, Germany.
The resulting seeds were planted during the following winter. The resulting seedlings were evaluated and exhibited distinctive physical and biological characteristics. The new rose plant was selected as a single plant from the seedling beds due to its superior characteristics and asexually propagated for further evaluation. This new and distinctive rose variety is named ‘KORcasima’.
The new rose plant ‘KORcasima’ was selected in May, 2003 from the seedling beds to be asexually propagated for further evaluation. The first asexual propagation of ‘KORcasima’ was done by budding to seedling understocks in July, 2003 at the inventor's nursery in Offenseth-Sparrieshoop, Germany.
This initial and other subsequent propagations conducted in controlled environments demonstrate that ‘KORcasima’ reproduces true to type in successive generations of asexual reproduction.
COMPARISON WITH PARENTS
The ‘KORcasima’ may be distinguished from its seed parent, an ‘un-named seedling’, by the following combination of characteristics:
-
The flower size of the ‘un-named seedling’ is small, while the flower size of ‘KORcasima’ is medium to large.
-
The petal count of the ‘un-named seedling’ is semi-double, while the petal count of ‘KORcasima’ is very double.
The new rose plant may be distinguished from its pollen parent, an ‘Insel Mainau’ by the following combination of characteristics:
-
The disease resistance of ‘Insel Mainau’ is poor, while the disease resistance of ‘KORcasima’ is good.
-
The height of ‘Insel Mainau’ is 40–50 cm, while the height of ‘KORcasima’ is 70–80 cm.
