White spruce tree named ‘Charlie J. Nickel’

Abstract

A new cultivar of white spruce tree named ‘Charlie J. Nickel’ that is characterized by its needles that are tinted blue in color, its uniform ovate-shaped plant habit with a strong central leader, and its good growth rate.

Description

Botanical classification: Picea glauca var. densata.

Varietal denomination: ‘Charlie J. Nickel’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Picea glauca var. densata and will be referred to hereafter by its cultivar name, ‘Charlie J. Nickel’. ‘Charlie J. Nickel’ represents a new cultivar of black hills white spruce, an evergreen plant grown for landscape use.

The inventor discovered ‘Charlie J. Nickel’ as a chance seedling in March of 2001 that was growing in a row of unnamed plants of Picea glauca var. densata that had been lined out in a field plot at his nursery in Manhattan, Kans. The parent plants are therefore unknown. The instant plant may be referred to as a white spruce, a black hills white spruce, or a black hills spruce.

Asexual propagation of the new cultivar was first accomplished by grafting onto Norway Spruce rootstock in McMinnville, Oreg. in January of 2002 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 ‘Charlie J. Nickel’ as a unique cultivar of black hills spruce.

• 1. ‘Charlie J. Nickel’ exhibits needles that are tinted blue in color.
• 2. ‘Charlie J. Nickel’ exhibits a uniform ovate-shaped plant habit with a strong central leader.
• 3. ‘Charlie J. Nickel’ exhibits a good growth rate.

The unnamed plants of Picea glauca var. densata that were growing in the area of discovery differ from ‘Charlie J. Nickel’ in having foliage that is greener in color, in lacking a uniform in shape, and in having a slower growth rate. ‘Charlie J. Nickel’ can be most closely compared to the Picea glauca var. densata cultivars ‘Westervelt’ (U.S. Plant Pat. No. 29,825) and ‘Wiskey Blue Hills’ (not patented). ‘Westervelt’ is similar to ‘Charlie J. Nickel’ in having blue tinted foliage and in growth rate but differs from ‘Charlie J. Nickel’ in having a narrow plant habit. ‘Wiskey Blue Hills’ is similar to ‘Charlie J. Nickel’ in having blue foliage but differs from ‘Charlie J. Nickel’ in having a slower growth rate, a more pyramidal and semi-compact plant habit with a smaller mature plant size.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

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 prior to the filing date but less than one year prior to the effective filing date.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of the new cultivar as taken from 2-year-old trees as grown outdoors in 1-gallon containers in McMinnville, Oreg.
