tree named ‘Butterfield’

Abstract

A new cultivar of Juniperus virginiana plant named ‘Butterfield’ that is characterized by its soft, bright gold foliage in cold winter temperatures and in hot summer temperatures, it's very uniform growth habit and upright plant habit and its strong central leader.

Description

Botanical classification: Juniperus virginiana.

Varietal denomination: ‘Butterfield’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Juniperus and will be referred to hereafter by its cultivar name, ‘Butterfield’. ‘Butterfield’ is a new cultivar of juniper, an evergreen shrub grown for use as an ornamental landscape plant.

The inventor discovered ‘Butterfield’ as a chance seedling in January of 2014 that was growing in a field of unnamed and unpatented plants of Juniperus virginiana that was found in a residence yard in rural Lyon County, Kans.

Asexual propagation of the new cultivar was first accomplished by grafting onto Juniperus ‘Hetzi’ (not patented) understock in Manhattan, Kans. in January of 2014 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 ‘Butterfield’ as a unique cultivar of Juniperus.

• 1. ‘Butterfield’ exhibits soft, bright gold foliage in cold winter temperatures and in hot summer temperatures.
• 2. ‘Butterfield’ exhibits a very uniform growth habit and upright plant habit.
• 3. ‘Butterfield’ exhibits a strong central leader.

The plants that were present in the field that ‘Butterfield’ was discovered in were typical plants of the species Juniperus virginiana as there were no named cultivars amongst them. The plants all differed in lacking gold foliage in cold temperatures and in having non-uniform growth habits, and in lacking central leaders. ‘Butterfield’ can be compared to Juniperus chinesis cultivar ‘Perfecta’ (not patented) and Juniperus communis cultivar ‘Gold Cone’ (not patented). ‘Perfecta’ and ‘Gold Cone’ are both similar to ‘Butterfield’ in having an upright habit. ‘Perfecta’ differs from ‘Butterfield’ in having foliage that is all green in color that is not as soft in texture and a growth habit that is less uniform in habit and shape. ‘Gold Cone’ differs from ‘Butterfield’ in having foliage that is not soft in texture and duller gold in color and in having a slower growth habit and a smaller plant size.

BRIEF DESCRIPTION OF THE DRAWING

The plant and plant parts depicted in the accompanied photograph illustrates the characteristics of ‘Butterfield’. The photograph was taken of a four-year-old plant as grown outdoors in a 3-gallon container in Manhattan, Kans. FIG. 1 provides an overall view of the plant habit of ‘Butterfield’. The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Juniperus.

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 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.
