Norway spruce tree named ‘Andy Spinks’

Abstract

A new cultivar of Norway spruce tree named ‘Andy Spinks’ that is characterized by its new and maturing foliage that is golden-tinted in color with older and shaded foliage blue-green in color, its strong central leader, its very uniform growth habit and shape, and its good growth rate.

Description

Botanical classification: Picea abies.

Varietal denomination: ‘Andy Spinks’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Picea abies and will be referred to hereafter by its cultivar name, ‘Andy Spinks’. ‘Andy Spinks’ represents a new hybrid of Norway spruce, an evergreen plant grown for landscape use.

The inventor discovered ‘Andy Spinks’ as a naturally occurring branch mutation in March of 2007 on an unnamed and unpatented plant of Picea abies growing in a home landscape in Portland, Oreg.

Asexual propagation of the new cultivar was first accomplished by grafting onto rootstock of Picea abies in McMinnville, Oreg. in January of 2020 under the direction of the Inventor. Asexual propagation by grafting has determined that the characteristics of this cultivar 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 cultivar. These attributes in combination distinguish ‘Andy Spinks’ as a unique cultivar of Picea.

• 1. ‘Andy Spinks’ exhibits new and maturing foliage that is golden-tinted in color with older and shaded foliage blue-green in color.
• 2. ‘Andy Spinks’ exhibits a strong central leader.
• 3. ‘Andy Spinks’ exhibits a very uniform growth habit and shape.
• 4. ‘Andy Spinks’ exhibits a good growth rate.

The parent plant of ‘Andy Spinks’ differs from ‘Andy Spinks’ in having green needles. ‘Andy Spinks’ can be most closely compared to the cultivars ‘Gold Drift’ (not patented) and ‘Golden Finch’ (not patented). Both are similar to ‘Andy Spinks’ in being hardy in U.S.D.A. Zones 2 to 6 and in having gold tinted foliage. ‘Golden Finch’ is also similar to ‘Andy Spinks’ in having foliage that is also similar in shape and size. ‘Gold Drift’ and ‘Golden Finch’ both differ from ‘Andy Spinks’ in having a less uniform growth habit and more weeping plant habits. In addition, ‘Golden Finch’ differs from ‘Andy Spinks’ in having a more dwarf plant habit.

BRIEF DESCRIPTION OF THE DRAWING

The plant depicted in the accompanied photograph illustrates the characteristics of ‘Andy Spinks’. The photograph was taken of a plant about 4 years in age as grown in the ground in Gresham, Oreg. and provides an overall view of the plant habit and foliage coloration of ‘Andy Spinks’. The colors in the photograph is as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describes the colors of the new Picea.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the new cultivar as taken from 3-year-old trees as grown outdoors in 3-gallon containers in Manhattan, Kans. 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.
