CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2022/0668 filed on Mar. 12, 2022, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Coprosma repens and will be referred to hereafter by its cultivar name, ‘ALDAWN’. ‘ALDAWN’ represents a new cultivar of evergreen shrub grown for landscape use.

The new cultivar was discovered by the Inventor in autumn of 2016 as a naturally occurring branch mutation of Coprosma ‘Pacific Dawn’ (not patented) in a trial field in Waunfawr, Gwynedd, United Kingdom.

Asexual propagation of the new cultivar was first accomplished by the Inventor by softwood stem cuttings in 2019 in Caernarfon, Gwynedd, The United Kingdom. Asexual propagation of the new cultivar by softwood stem cuttings has determined that the characteristics are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Coprosma. These attributes in combination distinguish ‘ALDAWN’ as a unique cultivar of Coprosma.

• • 1. ‘ALDAWN’ exhibits variegated foliage dark purple-green centers and margins that are vibrant pink when in late summer and fall with cool temperatures.

The parent plant of ‘ALDAWN’, differs from ‘ALDAWN’ in having foliage that is less intense in color. ‘ALDAWN’ can be most closely compared to the Coprosma cultivars ‘Pacific Night’ (not patented) and ‘Fire Burst’ (U.S. Plant Pat. No. 14,906). Both ‘Pacific Night’ and ‘Fire Burst’ are similar to ‘ALDAWN’ in having colored foliage. ‘Pacific Night’ differs from ‘ALDAWN’ in having foliage that is dark purple in color and a more narrow and upright plant habit. ‘Fire Burst’ differs from ‘ALDAWN’ in having foliage variegation that is purple and pink-red in color and a more rounded plant habit.

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales that fall within a one-year grace period prior to the filing date. Disclosures include website listings by Genesis Plant Marketing (the breeder's representative), Shoot Gardening, Worfield Plants, Kernock Park Plants, Gardeners Dream (and Amazon), Carbeth Plants, Grasslands, Twitter (by inventor) and GuiadeJardineria.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Coprosma. The photographs In FIG. 1 and FIG. 2 were taken of a 2-year-old plant as grown in a greenhouse in a P-9 container in Caernarfon, Gwynedd, The United Kingdom.

The photograph in FIG. 1 provides a side view of the plant habit of ‘ALDAWN’ in summer.

The photograph in FIG. 2 provides a close-up view of the foliage of ‘ALDAWN’ in summer.

The Photograph in FIG. 3 was taken of a 2-year-old plant growing in a trial garden in Colchester, Essex, The United Kingdom and provides a view of the fall foliage of ‘ALDAWN’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Coprosma.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 2-year-old plants of the new cultivar as grown in a greenhouse in P-9 containers in Caernarfon, Gwynedd, The United Kingdom The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
