Pelargonium plant named ‘Fisroccal’

Abstract

A new cultivar of Pelargonium particularly characterized by having salmon-orange, semi-double flowers, large inflorescences, long and strong peduncles, medium green foliage with weak zonation, a round, bushy plant habit with vigorous growth, and a mid-season flowering response is disclosed.

Description

Genus and species: Pelargonium×hortorum.

Variety denomination: ‘Fisroccal’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Pelargonium, botanically known as Pelargonium×hortorum, a hybrid of Pelargonium zonale L'Héritier and hereinafter referred to by the cultivar name ‘Fisroccal’. The new cultivar is a product of a planned breeding program which had the objective of creating new varieties having orange semi-double flowers, deep green zonation of foliage, and a vigorous but well-branched growth habit. ‘Fisroccal’ was discovered as a seedling resulting from a cross between the female parent, ‘Fip 440’ (U.S. Plant Pat. No. 13,964), which has orange-red semi-double flowers, medium green foliage with distinct zonation, and a vigorous growth habit and the male parent, ‘Dueimap’ (U.S. Plant Pat. No. 13,241), which has bright orange, semi-double flowers, grass-green foliage without or with very slight zonation, and a medium-sized plant habit.

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 Hillsheid, Germany, over a four-year period. ‘Fisroccal’ 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. ‘Fisroccal’ reproduces true to type in successive generations of asexual reproduction.

Plant Breeder's Rights for this cultivar were applied for in Germany on Jun. 2, 2004. No sales or offers for sale of this cultivar have been made before early July 2004.

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. Salmon-orange, semi-double flowers with good stability of flower color;
  • 2. Large inflorescences on long, strong peduncles;
  • 3. Medium-green foliage with weak zonation;
  • 4. Tall, moderately tight plant habit with vigorous growth;
  • 5. A mid-season flowering response; and
  • 6. Fair rain resistance.

DESCRIPTION OF PHOTOGRAPH

This new geranium 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 twelve-week-old plant grown from rooted cuttings, grown in 14-cm pots, left un-pinched, and grown under greenhouse conditions which approximate those generally used in commercial practice.

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

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Fisroccal’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on twelve-week-old, un-pinched plants grown in 14-cm pots in a greenhouse during mid-May. 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).

COMPARISON WITH KNOWN CULTIVARS

Of the many commercial cultivars known to the present inventor, the most similar in comparison to ‘Fisroccal’ are the related varieties ‘Fip 440’ (U.S. Plant Pat. No. 13,964) and ‘Dueimap’ (U.S. Plant Pat. No. 13,241) and the commercial variety ‘Americana Coral’ (U.S. Plant Pat. No. 7,934).

Cultivar ‘Fisroccal’ differs from the female parent variety ‘Fip 440’ (U.S. Plant Pat. No. 13,964) in that the flowers of ‘Fisroccal’ are lighter in color with a more salmon-colored hue and it has leaves with less distinct zonation.

Cultivar ‘Fisroccal’ differs from the male parent ‘Dueimap’ (U.S. Plant Pat. No. 13,241) in that the flower color of ‘Fisroccal’ has a less deep orange and more salmon hue than ‘Dueimap’. Additionally, the foliage of ‘Fisroccal’ develops somewhat stronger zonation, it has larger umbels that are higher above the foliage, and the growth habit is generally more vigorous than that of ‘Dueimap’.

Cultivar ‘Fisroccal’ differs from the commercial variety ‘Americana Coral’ (U.S. Plant Pat. No. 7,934) in that ‘Fisroccal’ has a flower color that is slightly more orange in hue, has slightly wider inflorescences, and has somewhat smaller leaves with weak zonation. Additionally, ‘Americana Coral’ exhibits either no zonation or zonation that is very weak on its immature leaves.
