Pelargonium plant named ‘Fisorangtan’

Abstract

A new cultivar of Pelargonium particularly characterized by the combined features of large, salmon-orange, semi-double flowers, large inflorescences, dark green and slightly zoned foliage, a round and bushy plant habit with compact to medium growth, and an early to mid-season flowering response is disclosed.

Description

Genus and species: Pelargonium×hortorum.

Variety denomination: ‘Fisorangtan’.

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 ‘Fisorangtan’. The new cultivar is a product of a planned breeding program which had the objective of creating new varieties having orange, semi-double flowers, dark green, zoned foliage, and a well-branched growth habit with moderately vigorous growth. ‘Fisorangtan’ was discovered as a seedling resulting from a cross between the female parent, ‘Fisrocky Orange’ (U.S. Plant Pat. No. 12,365), which has orange, semi-double flowers, and dark green foliage with a narrow ring of zonation and the male parent, ‘Dueimap’ (U.S. Plant Pat. No. 13,241), which has bright orange, semi-double flowers, medium green foliage with weak zonation, and a compact to medium growth 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 Hillscheid, Germany, over a four-year period. ‘Fisorangtan’ 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. ‘Fisorangtan’ 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 were 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. Large salmon-orange, semi-double flowers with good stability of flower color;
  • 2. Large inflorescences on relatively short peduncles and no shattering of petals;
  • 3. Dark green foliage with weak zonation;
  • 4. Rounded and very well branched with a compact to medium plant habit;
  • 5. A mid-season flowering response; and
  • 6. Good stability of flower color and good 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 ‘Fisorangtan’. 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 ‘Fisorangtan’ are the related varieties ‘Fisrocky Orange’ (U.S. Plant Pat. No. 12,365) and ‘Dueimap’ (U.S. Plant Pat. No. 13,241) and the commercial cultivar ‘Gensoran’ (unpatented).

Cultivar ‘Fisorangtan’ differs from the female parent ‘Fisrocky Orange’ (U.S. Plant Pat. No. 12,365) in that ‘Fisorangtan’ has a somewhat deeper and more brilliant flower color and exhibits very little fading. Additionally, the upper surface of the leaves of ‘Fisorangtan’ exhibits a slightly weaker and narrower zonation than that of ‘Fisrocky Orange’.

Cultivar ‘Fisorangtan’ differs from the male parent ‘Dueimap’ (U.S. Plant Pat. No. 13,241) in that the flowers of ‘Fisorangtan’ are less orange in color and the foliage is darker green than that of ‘Dueimap’.

Cultivar ‘Fisorangtan’ differs from the commercial comparison variety ‘Gensoran’ (unpatented) in that the flower color of ‘Gensoran’ is a more brilliant orange and the inflorescences are composed of more, but smaller flowers Additionally, the peduncles of ‘Gensoran’ are partly reddish (on the side of the peduncle), while the peduncles of ‘Fisorangtan’ are mainly green with a weak infusion of brown near the upper end.
