Abstract

A new and distinct cultivar of geranium known by the cultivar name `Miro` is characterized by a salmon flower color, a semi-double flower form, dark foliage, medium zonation and a compact habit.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of geranium botanically known as Pelargonium zonale, and hereinafter referred to by the cultivar name `Miro`.

`Miro` is a product of planned breeding program which had the objective of creating new geranium cultivars with salmon flower color, semi-double flower form, dark foliage, early flower response.

`Miro` was originiated from a hybridization made in a controlled breeding program in Hagenbach, Germany, in 1991. The female parent was `Hagenbacher Lachs`, characterized by its salmon-pink flower color, semi-double flower form and medium green foliage. The male parent of `Miro` was `Hoennefruhling`, characterized by its light salmon-pink flower color, single flower form, strong zonation and very early flower response. Neither of the parent plants is patented or presently available on a commercial basis. Its semi-double flower distinguishes `Miro` from `Hoennefruhling` and its dark foliage distinguishes `Miro` from the medium green foliage of `Hagenbacher Lachs`.

`Miro` was discovered and selected as one flowering plant within the progeny of the stated cross by the inventors in September 1992 in a controlled environment in Hagenbach, Germany.

BACKGROUND OF THE NEW PLANT

The first act of asexual reproduction of miro was accomplished when vegetative cuttings were taken from the initial selection in January 1993 in a controlled environment in Hagenbach, Germany, by a technician working under formulations established and supervised by Gerd Endisch.

Horticultural examination of selected units initiated in May 1983 had demonstrated that the combination of characteristics as herein disclosed for `Miro` are firmly fixed and are retained through successive generations of asexual reproduction.

`Miro` has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and day length. The following observations, measurements, and comparisons describe plants grown in Hagenbach, Germany, under field conditions which approximate those generally used in commercial practice. The dimensions and measurements given below are approximate.

The following traits have been repeatedly observed and are determined to be basic characteristics of `Miro` to distinguish this geranium as a new and distinct cultivar:

1. salmon flower color

2. semi-double flower form

3. dark Foliage

4. medium zonation

5. compact habit

Of the many commercial cultivars known to the present inventor, the most similar in comparison to `Miro` is `Unica.`. Reference is made to Chart A below which compares certain characteristics of `Micro` to those same characteristics of `Unica`. In comparison to `Unica`, `Miro` exhibits leaf zonation, earlier flowers response and better salmon color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawing shows typical flower and foliage characteristics of `Miro` with colors being as true as possible with illustrations of this type.

DETAILED BOTANICAL DESCRIPTION
