Title: Juniper plant--`Loree Dawn` variety

Description:
SUMMARY OF INVENTION 
     The present invention comprises a new and distinct variety of Juniperus chinensis that has been named the `Loree Dawn` variety. 
     The new `Loree Dawn` variety is a spontaneous mutation of unknown causation which was discovered and carefully preserved during the late 1970&#39;s in the course of plant selection work conducted at Blairsville, Pa., U.S.A. A single branch of a single plant of Juniperus chinensis `Pfitzeriana Aurea` (non-patented in the United States) was found to exhibit a distinctive foliage appearance unlike that exhibited by all other plants grown in the area. The parent `Pfitzeriana Aurea` plant sometimes is known as the `Gold Tip`0 variety. Had we not discovered and preserved this new plant it would have been lost to mankind. 
     It was found that the new variety of Juniperus chinensis: 
     (a) grows more slowly than `Pfitzeriana Aurea`, 
     (b) exhibits an attractive, fine and lacy-textured, brilliant gold foliage that is deeper and more persistent than that of `Pfitzeriana Aurea`, and 
     (c) exhibits a more compact and more prostrate growth habit than that of `Pfitzeriana Aurea`. 
     The golden foliage coloration is of a more vivid yellow than the typical golden Juniperus chinensis, such as `Pfitzeriana Aurea`. The foliage is speckled in appearance throughout the plant. More specifically, the foliage color of the new variety is a speckled brilliant gold and bright green on a variegated background of frost blue, green and gold. The slow growth and prostrate growth habit of the new variety enables the grower to well retain the desired overall appearance of the planting over an extended period of time. 
     Mature plants propagated from the original mutation have reached a height of approximately 12 to 18 inches and a width of approximately 36 to 48 inches. The winter hardiness of the new variety has been confirmed at both Blairsville and West Grove, Pa., U.S.A. 
     The plants of this new variety have been found to retain excellent color with a bright, fresh appearance even during the winter months. The degree of color fading tends to be minimal to none. Also plants of the new variety undergo shearing well while still retaining an attractive appearance. 
     Asexual propagation of the new variety has been successfully carried out since 1984 at Blairsville and West Grove, Pa., U.S.A. Rooted cuttings have repeatedly demonstrated that the characteristics of the new variety as discussed herein are firmly fixed and are retained through successive generations of asexual propagation. For instance, the new variety can be readily propagated through the use of hardwood cuttings during the winter. Alternatively, during the summer cuttings of new growth can be placed under mist. The new asexually reproduced plants produced from cuttings have been found to grow vigorously, are true-to-type, and have encounted few problems from insects or diseases. There have been no observed reversions of the new variety to the parent variety during the entire period of its observation. 
     The new variety because of its distinctive foliage coloration, texture and growth habit, was found to be particulary suited for growing as a specimen plant, as a foundation planting, or as a decorative mass planting. It lends itself well to conventional production methods and cultural practices when grown either in field or in containers, and well meets the demands of the modern landscape. Dense compact finely-textured plants are provided that require little maintenance while imparting an attractive vivid coloration to the landscape throughout the entire year. 
     The new variety, in view of its novel combination of characteristics, can be readily distinguished from all other golden Juniperus chinensis such as `Pfitzeriana Aurea`. For instance, the new variety exhibits a different golden coloration than `Pfitzeriana Aurea`. The foliage of new variety is more speckled and flecked. The coloration is also more vivid and covers the entire plant. As stated, the golden foliage coloration commonly persists throughout the summer and winter months whereas other golden junipers commonly assume a brownish-green foliage coloration during the winter months. When the new variety is grown side-by-side with the `Pfitzeriana Aurea` juniper and the `Bakaurea` juniper (U.S. Plant Pat. No. 3,801), the differences in foliage coloration are readily apparent. Also, the speckled appearance of the foliage of the new variety is absent in the `Gold Lace` variety (U.S. Plant Pat. No. 8,202). 
    
    
     BRIEF DESCRIPTION OF THE PHOTOGRAPHS 
     The accompanying photographs show as nearly true as it is reasonably possible to make the same in color illustrations of this character, typical specimens of the plant and plant parts of the new variety. The plants depicted in the photographs were grown in Blairsville, Pa., U.S.A. 
     FIG. 1.--illustrates the typical early summer appearance of young plants of the new variety on the right as compared to the appearnce of Juniperus chinensis `Bakaurea` (U.S. Plant Pat. No. 3,801) on the left. A blue spruce is shown in the background. 
     FIG. 2.--illustrates the typical mid-summer appearance of the new variety at the center following two seasons of growth wherein the summer coloration can be contrasted to that of a typical blue juniper at the left. 
     FIG. 3.--illustrates a closer perspective view of the typical texture and summer coloration of the foliage of the new variety. 
     FIG. 4.--illustrates during early summer differences in typical foliage texture and coloration between Juniperus chinensis `Pfitzeriana Aurea` on the left and the new variety on the right.
