USPP18973P2 - Pelargonium plant named ‘Fisrello’ - Google Patents

Abstract

A new cultivar of pelargonium particularly characterized by having bi-colored white and salmon-pink, semi-double, round flowers, medium-green foliage with weak zonation, a medium sized, rounded, well-branched and mounding plant habit, a high proportion of inflorescences to the foliage canopy and an early flowering response, is disclosed.

Description

Genus and species: Pelargonium×hortorum.

Variety denomination: ‘Fisrello’.

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 ‘Fisrello’. The new cultivar is a product of a planned breeding program which had the objective of creating a range of new medium-sized varieties having light-pink or light-salmon flowers, a good stability of flower color and medium-green foliage. ‘Fisrello’ was discovered as a seedling resulting from the self-pollination of the proprietary pelargonium plant ‘I92-61-2’ (unpatented), having light-pink to white, semi-double flowers.

The new cultivar was created in 1993 (self-pollination occurred in 1993 and selection of the off-spring occurred in 1994) in Hillscheid, Germany and has been asexually reproduced repeatedly by vegetative cuttings in Galdar, Gran Canaria, Spain, and Hillscheid, Germany over a twelve-year period. It has also been found to retain its distinctive characteristics through successive asexual propagations. ‘Fisrello’ 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 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. Semi-double, bi-colored light salmon-pink to white flowers;
  • 2. Floriferous with medium-sized inflorescences;
  • 3. Medium-green foliage with weak zonation;
  • 4. A medium sized plant habit;
  • 5. A rounded, well-branched and mounding plant habit; and
  • 6. An early flowering response.

DESCRIPTION OF THE PHOTOGRAPH

This new pelargonium plant is illustrated by the accompanying photograph which shows 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 photograph is of a plant approximately 14-weeks-old, un-pinched plant grown from rooted cuttings, in 14-cm pots and grown under greenhouse and outdoor conditions which approximate those generally used in commercial practice.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘Fisrello’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 11-week-old, un-pinched plants in 12-cm pots in a greenhouse during late-May. Color readings were taken under natural light in mid-May from flowers grown in the greenhouse. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Fisrello’ differs from the parent plant ‘I92-61-2’ (unpatented) by having leaves with more distinct zonation, while ‘I92-61-2’ has no leaf zonation. In addition, ‘Fisrello’ has a slightly deeper green foliage color than ‘I92-61-2’.

‘Fisrello’ differs from the commercial variety ‘Fisaqua’ (U.S. Plant Pat. No. 15,009) in that ‘Fisrello’ has bi-colored white and light salmon-pink flowers, while ‘Fisaqua’ has light-pink to light-rose flowers. Additionally, ‘Fisrello’ has shorter peduncles, smaller leaves, better branching and an earlier and more continuous flowering response than ‘Fisaqua’.

‘Fisrello’ differs from the commercial variety ‘Designer Light Pink’ (U.S. Plant Pat. No. 8,552) in that ‘Fisrello’ has bi-colored white and light salmon-pink flowers, while ‘Designer Light Pink’ has pink-lavender flowers.
