pelargonium plant named ‘Fistarol’

Abstract

A new cultivar of Pelargonium particularly characterized by having light red to coral, semi-double flowers with medium-sized inflorescences, dark-green foliage with medium-sized leaves and strong zonation, a vigorous growth habit, a relatively tall, rounded, bushy and tight plant habit and an early to mid-season flowering response, is disclosed.

Description

Genus and species: Pelargonium×hortorum.

Variety denomination: ‘Fistarol’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Pelargonium, botanically known as Pelargonium×hortorum and hereinafter referred to by the cultivar name ‘Fistarol’. The new cultivar is a product of a planned breeding program which had the objective of creating new varieties having pink flowers, good flower color stability, medium green foliage and vigorous growth. ‘Fistarol’ was discovered as a seedling resulting from a cross between the proprietary female parent ‘K92-1044-3’ (unpatented), a pelargonium having deep salmon-colored flowers and the male parent, ‘Fisvita’ (U.S. Plant Pat. No. 15,011), a pelargonium having light salmon and white semi-double flowers. A single plant selection was chosen for further evaluation and for asexual propagation in 2003.

The new cultivar was created in 2002 in Hillscheid, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Galdar, Gran Canaria, Spain, and Hillscheid, Germany, over a 4-year period. ‘Fistarol’ has not been observed under all possible environmental conditions, thus the phenotype may vary significantly with variations in the environment such as temperature, light intensity and day length. It has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar were applied for in Germany on Apr. 25, 2006 and in Canada on Apr. 26, 2006.

SUMMARY OF THE INVENTION

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

• • 1. Light red to coral, semi-double flowers;
  • 2. Medium-sized inflorescences that are initially short and later are borne well above the foliage;
  • 3. Dark-green, nearly round, medium-sized leaves with strong zonation;
  • 4. A vigorous growth habit and a relatively tall plant habit;
  • 5. A rounded, bushy and moderately tight plant habit; and
  • 6. An early to mid-season flowering response.

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 and un-pinched plant about 14-weeks-old and grown from rooted cuttings in a 14-cm pot under greenhouse conditions which approximate those generally used in commercial practice.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Fistarol’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 10-week-old, un-pinched plants in 12-cm pots in a greenhouse in mid-May 2006. The color readings were determined under natural light in mid-May from flowers grown in a greenhouse. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).
