USPP18721P2 - Pelargonium plant named ‘Gramon ’ - Google Patents

Abstract

A new cultivar of pelargonium particularly characterized by having salmon-orange, single, stellar-type flowers with relatively long peduncles, floriferous with medium-sized inflorescences borne well-above the foliage, medium-green foliage with strong zonation, a medium to tall-sized, rounded and well-branched plant habit, an early and continuous flowering response and good resistance to rain, is disclosed.

Description

Genus and species: Pelargonium×hortorum.

Variety denomination: ‘Gramon’.

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 ‘Gramon’. The new cultivar is a product of a planned breeding program which had the objective of creating new varieties having stellar-type flowers, medium-green foliage, medium-sized and well branching plants in a variety of flower colors. ‘Gramon’ was discovered as a seedling resulting from the cross of the female parent ‘K99-4006-2’ (unpatented), proprietary pelargonium plant having light-salmon, single-type flowers and the male parent ‘K00-5035-15’ (unpatented), a proprietary pelargonium plant having pink double flowers.

The new cultivar was created in 2001 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. ‘Gramon’ has been found to retain its distinctive characteristics through successive asexual propagations, ‘Gramon’ 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. Single, stellar-type, salmon-orange flowers with relatively long peduncles;
  • 2. Floriferous with medium-sized inflorescences well-above the foliage;
  • 3. Medium-green foliage with strong zonation;
  • 4. Medium-sized or taller plant habit;
  • 5. A rounded, well-branched and bushy plant habit;
  • 6. Good rain resistance; and
  • 7. An early and continuous 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 an about 14-week-old, un-pinched plant grown from rooted cuttings, in 12-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 ‘Gramon’. The data which define these characteristics were collected from asexual reproductions carried out in Hillscheid, Germany. The plant history was taken on 12-week old, un-pinched plants in 12-cm pots in a greenhouse during late May. Color readings were taken under natural light in late May from flowers grown in the greenhouse. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (RHS) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS

‘Gramon’ differs from the female parent ‘K99-400602’ (unpatented) by having deeper salmon-orange flowers, while ‘K99-400602’ has light-salmon colored flowers.

‘Gramon’ differs from the male parent ‘K00-5035-15’ (unpatented) by having salmon-orange and single-type flowers, while ‘K00-5035-15’ has pink, double flowers.

‘Gramon’ differs from the commercial variety ‘Shalimar’ (unpatented) by having salmon-orange flowers, while ‘Shalimar’ has light-pink flowers. In addition, ‘Gramon’ has a shorter plant habit and shorter peduncles than ‘Shalimar’.

‘Gramon’ differs from the commercial comparison variety ‘Sunrise Salmon Flash’ (U.S. Plant Pat. No. 13,306) in that ‘Gramon’ has a deeper and more orange hue of flower color, while ‘Sunrise Salmon Flash’ has lighter, salmon-pink flowers (roughly RHS 55C and RHS 55D to RHS 52D). Additionally, ‘Sunrise Salmon Flash’ has somewhat smaller flowers, where the upper and lower petals are about equal size and has a more closed corolla shape (nearly no gaps between the petals).

‘Gramon’ differs from the commercial comparison variety ‘Grasalm’ (U.S. Plant Pat. No. 16,642) in that ‘Gramon’ has salmon-orange flowers, while ‘Grasalm’ has rose-red flowers.
