plant named ‘RIKAG’

Abstract

A new and distinct Juniperus cultivar named ‘RIKAG’ is disclosed, characterized by abundant fruit production and dense foliage. The new cultivar is a Juniperus chinensis, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Juniperus chinensis.

Variety denomination: ‘RIKAG’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a naturally occurring mutation. This new variety, hereinafter referred to as ‘RIKAG’, was selected as a single branch mutation of an unnamed, unpatented Juniperus chinensis. The new variety was discovered by the inventor Rika Bronsther in a commercial nursery in Hemstead, N.Y. during Spring of 2006.

After identifying the new variety as a potentially interesting selection, semi-hardwood cuttings were taken at the same nursery in Hemstead, N.Y., then taken to a commercial nursery in Grand Haven, Mich. for rooting in the Spring of 2006. Confidential, controlled testing and propagation, was conducted to assess the stability of the unique characteristics of this variety. At least four generations have been reproduced and have shown that the unique features of this cultivar are stable and reproduced true to type. First public access to plants of the variety occurred during August of 2018 in the United States. This offer came directly or indirectly from the inventor, qualifying for the exception allowed under 102(b). Previous to this sale, although the variety may have been publicized in print, plants were not available to the public for propagation.

SUMMARY OF THE INVENTION

The cultivar ‘RIKAG’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘RIKAG’ These characteristics in combination distinguish ‘RIKAG’ as a new and distinct Juniperus cultivar:

• • 1. Abundant fruit production.
  • 2. Dense foliage.

COMPARISON TO PARENT VARIETY

‘RIKAG’ is similar in most horticultural characteristics to the parent variety. Plants of the new cultivar ‘RIKAG’ however, differ in the following:

• • 1. The new variety has dense green foliage, while parent has less dense and darker green foliage.
  • 2. The new variety produces more fruit than the parent.

COMMERCIAL COMPARISON

In addition to the parent, ‘RIKAG’ can be compared to the commercial variety Juniperus chinensis ‘Hetzi Columnaris’, unpatented. The varieties are similar in most horticultural characteristics, however, plants of ‘RIKAG’ differ in the following:

• • 1. New cultivar has bright green foliage with a tinge of gold; comparator has darker green foliage with a bit of grey.
  • 2. Plants of the new variety are larger in diameter than this comparator.
  • 3. New variety produces blue fruit, while comparator produces blue-purple fruit.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘RIKAG’ grown outdoors in Grand Haven, Mich. The plant is approximately 7 years old, and is shown in the ground at a testing plot.

FIG. 2 illustrates a close up of a branch of the new variety, with fruits.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
