AI Technical Summary
There is a need for a new cultivar of Juniperus conferta that exhibits a dense and compact plant habit, light yellow young shoots, and mature green leaves, differing from existing cultivars like 'Allgold' and 'JAP08', which are similar but have distinct foliage colors and growth habits.
The development of a new cultivar, 'KA5', characterized by a dense and compact plant habit, light yellow young shoots, and mature green leaves, derived from a naturally occurring branch mutation of Juniperus conferta 'Schlager', achieved through asexual propagation by stem cuttings and stable reproduction via tissue culture and division.
The 'KA5' cultivar maintains its unique characteristics, offering a distinct ornamental landscape plant with moderate growth rate and cold hardiness to at least USDA Zone 6, without observed disease or pest susceptibility.

Abstract
Description
[0001] Botanical classification: Juniperus conferta.
[0002] Varietal denomination: ‘KA5’.BACKGROUND OF THE INVENTION
[0003] The present invention relates to a new and distinct cultivar of Juniperus and will be referred to hereafter by its cultivar name, ‘KA5’. ‘KAS’ is a new cultivar of juniper, an evergreen shrub grown for use as an ornamental landscape plant.
[0004] The new cultivar was discovered by the Inventor in May of 2020 as a naturally occurring branch mutation of Juniperus conferta ‘Schlager’ (not patented) growing in a container in Szadek, Poland.
[0005] Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor by stem cuttings in September of 2020 in Szadek, Poland. Propagation by tissue culture and division has determined the characteristics to be stable and reproduced true to type in successive generations.SUMMARY OF THE INVENTION
[0006] The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘KA5’ as a unique cultivar of Juniperus.
[0007] 1. ‘KA5’ exhibits a dense and compact plant habit.
[0008] 2. ‘KAS’ exhibits light yellow young shoots and mature green leaves.
[0009] 3. ‘KA5’ exhibits a moderate growth rate.
[0010] The parent plant of ‘KA5’ differs from ‘KA5’ in having a more vigorous plant habit and blue-green young shoots. ‘KA5’ can be compared to Juniperus cultivars ‘Allgold’ (not patented) and ‘JAP08’ (U.S. Plant Pat. No. 21,433). ‘Allgold’ and ‘JAP08’ are both similar to ‘KA5’ in having a flattened globular plant shape and a moderately vigorous growth habit. ‘Allgold’ differs in having foliage that is golden yellow in color and changes to orange-yellow in winter. ‘JAP08’ differs from ‘KA5’ in having young and mature foliage that is variegated with yellow patches throughout the plant.BRIEF DESCRIPTION OF THE DRAWINGS
[0011] The plant and plant parts depicted in the accompanied photographs illustrate the characteristics of ‘KA5’. The photographs were taken of an 18 month-old plant as grown outdoors in a 17-cm container in Meijel, The Netherlands.
[0012] The photograph in FIG. 1 provides an overall side view of the plant habit of ‘KA5’.
[0013] The photograph in FIG. 2 provides a close-up view of the young foliage of ‘KA5’.
[0014] The photograph in FIG. 3 provides a close-up view of the mature foliage of ‘KA5’.
[0015] 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
[0016] The following is a detailed description of the new cultivar as taken from an 18 month-old plant as grown outdoors in 17-cm containers in Meijel, The Netherlands.
