Abstract

A new and distinct cultivar of Lupine plant named ‘WCLRATH’, characterized by its upright plant habit; moderately vigorous to vigorous growth habit; numerous large light red purple and light yellow green bi-colored flowers arranged on dense terminal racemes; and good garden performance.

Description

Botanical designation: Lupinus hybrid.
Cultivar denomination: ‘WCLRATH’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Lupine plant, botanically known as Lupinus hybrid and hereinafter referred to by the name ‘WCLRATH’.
The new Lupine plant is a product of a planned breeding program conducted by the Inventor in Devon, United Kingdom. The objective of the breeding program is to develop new uniform and freely flowering Lupine plants with large attractive flowers.
The new Lupine plant originated from an open-pollination in June, 2012 of an unnamed selection of Lupinus Russell Hybrids, not patented, as the female, or seed, parent with an unknown selection of Lupinus hybrid as the male, or pollen, parent. The new Lupine plant was discovered and selected by the Inventor in June, 2012 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Devon, United Kingdom.
Asexual reproduction of the new Lupine plant by in vitro meristem culture in a controlled greenhouse environment in Hillegom, The Netherlands since March, 2013 has shown that the unique features of this new Lupine plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Lupine have not been observed under all possible combinations of environmental conditions and cultural practices. 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 ‘WCLRATH’. These characteristics in combination distinguish ‘WCLRATH’ as a new and distinct Lupine plant:
    • 1. Upright plant habit.
    • 2. Moderately vigorous to vigorous growth habit.
    • 3. Numerous large light red purple and light yellow green bi-colored flowers arranged on dense terminal racemes.
    • 4. Good garden performance.
Plants of the new Lupine can be compared to plants of the female parent selection. Plants of the new Lupine differ from plants of the female parent selection primarily in the following characteristics:
    • 1. Plants of the new Lupine are shorter than plants of the female parent selection.
    • 2. Plants of the new Lupine are more vigorous and healthier than plants of the female parent selection.
    • 3. Racemes of plants of the new Lupine are denser than racemes of plants of the female parent selection.
Plants of the new Lupine can be compared to plants of Lupinus hybrid ‘The Chatelaine’, not patented. Plants of the new Lupine differ primarily from plants of ‘The Chatelaine’ in the following characteristics:
    • 1. Plants of the new Lupine are shorter than plants of ‘The Chatelaine’.
    • 2. Plants of the new Lupine are more vigorous and healthier than plants of ‘The Chatelaine’.
    • 3. Plants of the new Lupine are more freely flowering than plants of ‘The Chatelaine’.
    • 4. Racemes of plants of the new Lupine are denser than racemes of plants of ‘The Chatelaine’.
    • 5. Plants of the new Lupine and ‘The Chatelaine’ differ in flower color as plants of ‘The Chatelaine’ have pink and white bi-colored flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Lupine 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 Lupine plant. The photograph on the first sheet is side perspective view of typical flowering plants of ‘WCLRATH’ grown in a ground bed. The photograph on the second sheet is a close-up view of a typical flowering plant of ‘WCLRATH’ grown in a ground bed.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants of the new Lupine grown during the spring and early summer in ground beds in an outdoor nursery in Hillegom, The Netherlands and under cultural practices typical of commercial Lupine production. During the production of the plants, day temperatures ranged from 13° C. to 27° C. and night temperatures ranged from 5° C. to 18° C. Plants were two years old when the photographs and the detailed description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
