USPP21755P2 - Gerbera plant named ‘Redwood’ - Google Patents

Abstract

A new and distinct cultivar of Gerbera plant named ‘Redwood’, characterized by its compact, upright and uniformly mounding plant habit; freely flowering habit; orange red-colored ray and disc florets; and upright, strong and relatively short scapes.

Description

Botanical designation: Gerbera jamesonii.

Cultivar denomination: ‘REDWOOD’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Gerbera plant, botanically known as Gerbera jamesonii and hereinafter referred to by the name ‘Redwood’.

The new Gerbera plant is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new compact container Gerbera cultivars with numerous inflorescences, good garden performance and attractive inflorescence coloration.

The new Gerbera plant originated from a cross-pollination during the summer of 2005 in De Kwakel, The Netherlands of Gerbera jamesonii ‘Flomountain’, disclosed in U.S. Plant Pat. No. 21,340, as the female, or seed, parent Gerbera jamesonii ‘Flopacific’, disclosed in U.S. Plant patent application Ser. No. 12/454,018, as the male, or pollen, parent. The new Gerbera plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Kwakel, The Netherlands during the spring of 2006.

Asexual reproduction of the new Gerbera plant by tissue culture in a controlled environment in De Kwakel, The Netherlands since the summer of 2006 has shown that the unique features of this new Gerbera plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Gerbera have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Redwood’. These characteristics in combination distinguish ‘Redwood’ as a new and distinct cultivar of Gerbera:

• • 1. Compact, upright and uniformly mounding plant habit.
  • 2. Freely flowering habit.
  • 3. Orange red-colored ray and disc florets.
  • 4. Upright, strong and relatively short scapes.

Plants of the new Gerbera differ from plants of the female parent, ‘Flomountain’, in the following characteristics:

• • 1. Plants of the new Gerbera are broader than plants of ‘Flomountain’.
  • 2. Leaves of plants of the new Gerbera have more rounded apices than leaves of plants of ‘Flomountain’.
  • 3. Ray florets of plants of the new Gerbera are red orange in color whereas ray florets of plants of ‘Flomountain’ are light orange and orange in color.

Plants of the new Gerbera differ from plants of the male parent, ‘Flopacific’, in the following characteristics:

• • 1. Plants of the new Gerbera have larger inflorescences than plants of ‘Flopacific’.
  • 2. Plants of the new Gerbera and ‘Flopacific’ differ in ray floret coloration as plants of ‘Flopacific’ have pink and red purple-colored ray florets.

Plants of the new Gerbera can be compared to plants of the Gerbera jamesonii ‘Flomite’, disclosed in U.S. Plant Pat. No. 21,309. Plants of the new Gerbera differ from plants of ‘Flomite’ in the following characteristics:

• • 1. Plants of the new Gerbera are shorter than plants of ‘Flomite’.
  • 2. Plants of the new Gerbera have smaller inflorescences than plants of ‘Flomite’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Gerbera plant. The photograph shows the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Gerbera plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Redwood’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in a glass-covered greenhouse during the spring and summer in De Kwakel, The Netherlands and under conditions and practices which approximate those generally used in commercial container Gerbera production. During the production of the plants, day temperatures ranged from 19° C. to 26° C. and night temperatures ranged from 16° C. to 18° C. Rooted young tissue-cultured plants were planted in 19-cm containers and were six months old when the photograph was taken and ten months old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, 2007, except where general terms of ordinary dictionary significance are used.
