Title: Euphorbia Plant Named ‘Bonpri 1482’

Inventor/Applicant: Andrew Bernuetz

Filed: Oct. 26, 2023

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Euphorbia plant, an interspecific hybrid botanically known as Euphorbia pulcherrima Willd. ex Klotzsch X Euphorbia cornastra, and hereinafter referred to by the cultivar name ‘Bonpri 1495’.

The new Euphorbia plant is a product of a planned breeding program conducted by the Inventor in Yellow Rock, New South Wales, Australia. The objective of the program is to create and develop new interspecific Euphorbia plants with compact, upright and mounded plant habit and attractive flower bracts.

The new Euphorbia plant is a naturally-occurring whole plant mutation of a proprietary selection of Euphorbia pulcherrima Willd. ex Klotzsch X Euphorbia cornastra identified as code number 1095, not patented. The new Euphorbia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of the mutation parent selection in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia in October, 2014.

Asexual reproduction of the new Euphorbia plant by terminal vegetative cuttings in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia since October, 2014 has shown that the unique features of this new Euphorbia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Euphorbia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength 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 ‘Bonpri 1495’. These characteristics in combination distinguish ‘Bonpri 1495’ as a new and distinct Euphorbia plant:

    • 1. Upright and mounded plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Large inflorescences with bright salmon pink-colored flower bracts.
    • 5. Good post-production longevity.

Plants of the new Euphorbia differ primarily from plants of the mutation parent selection in flower bract color as flower bracts of plants of the new Euphorbia are lighter in color than flower bracts of plants of the mutation parent selection. In addition, plants of the new Euphorbia are more freely branching than plants of the mutation parent selection.

Plants of the new Euphorbia can be compared to plants of the Euphorbia pulcherrima Willd. ex Klotzsch X Euphorbia cornastra ‘Bonpri 1482’, disclosed in a U.S. Plant patent application Ser. No. 18/384,217, filed concurrently. In side-by-side comparisons, plants of the new Euphorbia differ primarily from plants of ‘Bonpri 1482’ in the following characteristics:

    • 1. Plants of the new Euphorbia are somewhat shorter and broader than plants of ‘Bonpri 1482’.
    • 2. Plants of the new Euphorbia are more freely branching than plants of ‘Bonpri 1482’.
    • 3. Plants of the new Euphorbia fewer flower bracts per inflorescence than plants of ‘Bonpri 1482’.
    • 4. Plants of the new Euphorbia have smaller flower bracts per inflorescence than plants of ‘Bonpri 1482’.
    • 5. Plants of the new Euphorbia and ‘Bonpri 1482’ differ in flower bract color as flower bracts of plants of the new Euphorbia are bright salmon pink in color whereas flower bracts of plants of ‘Bonpri 1482’ are bright purplish red in color.

Plants of the new Euphorbia can also be compared to plants of the Euphorbia pulcherrima Willd. ex Klotzsch X Euphorbia cornastra ‘Bonpri 1095’, disclosed in U.S. Plant Pat. No. 28,676. In side-by-side comparisons, plants of the new Euphorbia differ primarily from plants of ‘Bonpri 1095’ in the following characteristics:

    • 1. Plants of the new Euphorbia are broader than plants of ‘Bonpri 1095’.
    • 2. Plants of the new Euphorbia are more freely branching than plants of ‘Bonpri 1095’.
    • 3. Leaves of plants of the new Euphorbia are larger than leaves of plants of ‘Bonpri 1095’.
    • 4. Leaves of plants of the new Euphorbia are lanceolate in shape whereas leaves of plants of ‘Bonpri 1095’ are deltoid or ovate in shape.
    • 5. Plants of the new Euphorbia have more flower bracts per inflorescence than plants of ‘Bonpri 1095’.
    • 6. Plants of the new Euphorbia have smaller flower bracts per inflorescence than plants of ‘Bonpri 1095’.
    • 7. Flower bracts of plants of the new Euphorbia are lanceolate in shape whereas flower bracts of plants of ‘Bonpri 1095’ are ovate in shape.
    • 8. Plants of the new Euphorbia and ‘Bonpri 1095’ differ in flower bract color as flower bracts of plants of the new Euphorbia are bright salmon pink in color whereas flower bracts of plants of ‘Bonpri 1095’ are red purple in color with lighter red purple-colored margins.
