USPP18549P2 - Pelargonium plant named ‘Fisburg’ - Google Patents

Abstract

A new cultivar of pelargonium particularly characterized by having deep-purple, single-type flowers, floriferous with medium-sized inflorescences on relatively short peduncles, deep-green foliage with distinct zonation in the center of the leaves, medium to tall size, trailing, well-branched plant habit and an early flowering response, is disclosed.

Description

Genus and species: Pelargonium peltatum L'Héritier.

Variety denomination: ‘Fisburg’.

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 ‘Fisburg’. The new cultivar is a product of a planned breeding program which had the objective of creating new ivy geraniums in a variety of colors, having large, single-type flowers and suitable for the range of vigorously growing varieties. ‘Fisburg’ was discovered as a seedling resulting from the cross of the female parent ‘K98-3029-14’ (unpatented), a proprietary pelargonium plant having purple, semi-double flowers and the male parent ‘Nelson Reip’ (unpatented), a commercial pelargonium plant having deep-purple, single-type flowers.

The new cultivar was created in 2000 in Hillscheid, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Galdar, Gran Canaria, Spain, and Hillscheid, Germany over a five-year period. It has been found to retain its distinctive characteristics through successive asexual propagations. ‘Fisburg’ reproduces true to type in successive generations of asexual reproduction.

Plant Breeder's Rights for this cultivar were applied for in Germany on Apr. 4, 2005 and in Canada on Apr. 20, 2005.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Hillscheid, Germany.

• • 1. Deep-purple, single-type flowers with good stability of flower color;
  • 2. Floriferous with medium to large inflorescences;
  • 3. Deep-green foliage with distinct zonation in the center of the leaf;
  • 4. A medium-sized to tall, well-branched, trailing plant habit; and
  • 5. An early-season flowering response.

DESCRIPTION OF THE PHOTOGRAPHS

This new pelargonium plant is illustrated by the accompanying photographs which show overall plant habit including inflorescences, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of three 30-week-old plants in a hanging basket in early September and grown under greenhouse and outdoor conditions which approximate those generally used in commercial practice.

FIG. 1 shows the overall plant habit with blooms, buds and foliage.

FIG. 2 shows a close-up view of an inflorescence taken under artificial light.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Fisburg’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 15-week old plants, pinched once, in 12-cm pots in a greenhouse during late May. Color readings were taken under natural light in mid-May in the greenhouse. Color references are primarily to the RHS Colour Chart in The Royal Horticultural Society of London (RHS) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Fisburg’ differs from the female parent ‘K98-3029-14’ (unpatented) by having single-type flowers, while ‘K98-3029-14’ has semi-double flowers. In addition, ‘Fisburg’ has a less compact plant habit than ‘K98-3029-14’.

‘Fisburg’ differs from the male parent ‘Nelson Reip’ (unpatented) by having wider, rounder petals and a lower tendency for the flower color to fade then ‘Nelson Reip’. In addition, ‘Fisburg’ grows somewhat less vigorously and has shorter internodes than ‘Nelson Reip’.

‘Fisburg’ differs from the commercial variety ‘Fisblipur’ (U.S. Plant Pat. No. 15,214) by having a less bluish, more deep purple-red hue of flower color than ‘Fisblipur’. In addition, ‘Fisburg’ grows less vigorously than ‘Fisblipur’.

‘Fisburg’ differs from the commercial variety ‘Fisruby’ (U.S. Plant Patent Pending) by having more bluish, single-type flowers, while ‘Fisruby’ has less bluish, double flowers.
