Lupine plant named ‘Terracotta’

Abstract

A new and distinct cultivar of Lupine plant named ‘Terracotta’, characterized by its upright plant habit; vigorous growth habit; numerous large orange red-colored flowers arranged on dense terminal racemes; and good garden performance.

Description

Botanical designation: Lupinus hybrid.

Cultivar denomination: ‘TERRACOTTA’.

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 ‘Terracotta’.

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, 2005 of a seedling selection of Lupinus hybrid identified as Lupinus Russell Hybrid Seedling WCL 024/62, 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, 2006 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 micro propagation in a controlled greenhouse environment in Hillegom, The Netherlands since March, 2009 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 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 ‘Terracotta’. These characteristics in combination distinguish ‘Terracotta’ as a new and distinct Lupine plant:

• • 1. Upright plant habit.
  • 2. Vigorous growth habit.
  • 3. Numerous large orange red-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 plant growth habit and flower color.

Plants of the new Lupine can be compared to plants of Lupinus hybrid ‘Manhattan Lights’, disclosed in U.S. Plant Pat. No. 18,868. Plants of the new Lupine differ from plants of ‘Manhattan Lights’ in the following characteristics:

• • 1. Plants of the new Lupine are shorter than plants of ‘Manhattan Lights’.
  • 2. Plants of the new Lupine and ‘Manhattan Lights’ differ in flower color as plants of ‘Manhattan Lights’ have burgundy and yellow-colored flowers.

Plants of the new Lupine can also be compared to plants of Lupinus hybrid ‘Saffron’, disclosed in U.S. Plant Pat. No. 18,802. Plants of the new Lupine differ from plants of ‘Saffron’ in the following characteristics:

• • 1. Plants of the new Lupine are taller than plants of ‘Saffron’.
  • 2. Plants of the new Lupine and ‘Saffron’ differ in flower color as plants of ‘Saffron’ have yellow-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 at the bottom of the second sheet is a close-up view of a typical leaf of ‘Desert Sun’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants of the new Lupine grown during the early summer in 3-liter containers in an outdoor nursery in Vogelenzang, The Netherlands and under cultural practices which closely approximate commercial Lupine production. During the production of the plants, day temperatures ranged from 16° C. to 26° C. and night temperatures ranged from 6° C. to 16° C. Plants were one year 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, 2007 Edition, except where general terms of ordinary dictionary significance are used.
