Abstract

A new and distinct cultivar of Alstroemeria plant named ‘Davina’, characterized by its compact and mounding plant habit; sturdy and strong plants; vigorous growth habit; salmon pink and yellow-colored flowers; and good garden performance.

Description

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘Davina’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, grown typically as a potted garden Alstroemeria, and hereinafter referred to by the name ‘Davina’.

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventor in Chichester, England. The objective of the breeding program is to create new compact potted garden Alstroemeria cultivars that have attractive foliage and flower coloration.

The new Alstroemeria plant originated from a cross-pollination made by the Inventor in Chichester, England in June, 2000, of a proprietary selection of Alstroemeria hybrida identified as code number T10, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as code number 465/1, not patented, as the male, or pollen, parent. The new Alstroemeria was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Chichester, England in May, 2002.

Asexual reproduction of the new Alstroemeria by tissue culture in a controlled greenhouse environment in Chichester, England since October, 2004, has shown that the unique features of this new Alstroemeria are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The new Alstroemeria has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Davina’. These characteristics in combination distinguish ‘Davina’ as a new and distinct cultivar of Alstroemeria:

- 1. Compact and mounding plant habit.
- 2. Sturdy and strong plants.
- 3. Vigorous growth habit.
- 4. Large salmon pink and yellow-colored flowers.
- 5. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the female parent selection. Plants of the new Alstroemeria differ from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Alstroemeria are more compact than plants of female parent selection.
- 2. Plants of the new Alstroemeria have larger flowers than plants of the female parent selection.
- 3. Plants of the new Alstroemeria and female parent selection differ in flower color as plants of female parent selection have lilac pink-colored flowers.

Plants of the new Alstroemeria can be compared to plants of the male parent selection. Plants of the new Alstroemeria differ from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Alstroemeria are more compact than plants of the male parent selection.
- 2. Plants of the new Alstroemeria have smaller flowers than plants of the male parent selection.
- 3. Plants of the new Alstroemeria and the male parent selection differ in flower color as plants of the male parent selection have pale orange-colored flowers.

Plants of the new Alstroemeria can be compared to plants of the Alstroemeria hybrida ‘Natalie’, disclosed in U.S. Plant Pat. No. 17,801. In side-by-side comparisons conducted in Chichester, England, plants of the new Alstroemeria differed from plants of ‘Natalie’ in the following characteristics:

- 1 Plants of the new Alstroemeria had larger flowers than plants of ‘Natalie’.
- 2. Plants of the new Alstroemeria and ‘Natalie’ differed in flower color as plants of ‘Natalie’ had red and white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Alstroemeria plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Davina’ grown in a container.

The photograph on the second sheet is a close-up view of typical flowers of ‘Davina’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Alstroemeria grown in Chichester, England during the summer in a glass-covered greenhouse in 16-cm containers. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 14° C. Plants used for the photographs and description had been growing for six months. Color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
