Abstract

A new cultivar of Pelargonium named ‘KLEPP08212’ particularly characterized as an ivy pelargonium with bi-colored red and light-pink inflorescences, a medium growth habit and branching, an upright and light trailing plant habit, stable inflorescence color; and good tolerance to heat and rain, is disclosed.

Description

Genus and species: Pelargonium peltatum.

Variety denomination: ‘KLEPP08212’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Pelargonium, botanically known as Pelargonium peltatum, and hereinafter referred to by the cultivar name ‘KLEPP08212’. ‘KLEPP08212’ was produced by grafting the Pelargonium plant ‘Mexicanerin’ (unpatented), which contains a unique viroid that causes dichroism, with the Pelargonium plant ‘Royal Scarlet’ (unpatented). ‘Mexicanerin’ was the rootstock and ‘Royal Scarlet’ was the scion. The selection criterion for the scion was good red color, zonated leaf, and good growth and branching. After the grafting method, shoot tip cuttings were taken and propagated. The viroid of ‘Mexicanerin’ passed to the grafting and yielded a new phenotype of bi-colored red-white. There was variation among the plants and selections were made based on color intensity. A single plant selection was subsequently chosen for further evaluation and for asexual propagation via vegetative cuttings. While the mechanism of the viroid is not known, the new trait of dichroism is stable and heritable in that it is passed on to future generations through asexual propagation without the rootstock. The selection criteria used to obtain the final variety was color, growth, and earliness of flowering.

The new cultivar was created in 2006 in Stuttgart, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Stuttgart, Germany over three to four generations. ‘KLEPP08212’ has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar have not been applied for. ‘KLEPP08212’ has not been made publicly available more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal commercial practices in a greenhouse in Stuttgart, Germany.

- 1. Ivy pelargonium with bi-colored red and light-pink inflorescences;
- 2. A medium growth habit and good branching;
- 3. An upright and light trailing plant habit;
- 4. Stable inflorescence color; and
- 5. Good tolerance to heat and rain.

DESCRIPTION OF THE PHOTOGRAPH

This new Pelargonium plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.

The photograph is of a plant about 3-months old taken in Spring 2008 and grown from rooted cuttings in a 12-cm pot under greenhouse (glasshouse) in Stuttgart, Germany under conditions which approximate those generally used in commercial practice.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘KLEPP08212’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. The plant history was taken on 3-month old plants in 12-cm pots in a greenhouse (glasshouse) in January through April 2008. The plants were pinched once at five weeks. The color readings were determined under natural light. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).
