Variety denomination: ‘GRLN01’.

CROSS-REFERENCE TO A RELATED APPLICATION

This application claims priority to European Community Plant Variety Office (CPVO) Plant Breeder's Rights Application No. 2020/0653 filed on Mar. 4, 2020 under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein.

This application is co-pending with a U.S. Plant Patent Applications filed for plants derived from the same breeding program that are entitled Lonicera Plant Named ‘GRLN02’ (U.S. Plant patent application Ser. No. 17/135,656) and Lonicera Plant Named ‘GRLN03’ (U.S. Plant patent application Ser. No. 17/135,656).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lonicera nitida and will be referred to hereafter by its cultivar name, ‘GRLN01’. ‘GRLN01’ is a new cultivar of boxleaf honeysuckle, an evergreen shrub grown for use as an ornamental landscape plant.

The new cultivar was derived from a controlled breeding program conducted by the Inventor at his nursery in Valkenburg, The Netherlands. The overall purpose of the breeding program is to make selections of Lonicera plants with new leaf colors and dense foliage. ‘GRLN01’ arose from crosses made in 2014 with Lonicera nitida ‘Red Tips’ (not patented) as the female parent and an unpatented and unnamed proprietary plants of Lonicera nitida from the Inventor's breeding program as the male parent. The seeds were pooled for the crosses and therefore the male parent is unknown. ‘GRLN01’ was selected as a single unique plant in 2015 from amongst the seedlings derived from the above crosses.

Asexual propagation of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in 2015 in Valkenburg, The Netherlands. Asexual propagation by softwood cuttings has determined that the characteristics of the new 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 ‘GRLN01’ as a new and distinct cultivar of Lonicera.

• • 1. ‘GRLN01’ exhibits an evergreen, winter hardy habit.
  • 2. ‘GRLN01’ exhibits a very dense, well-branched growth habit that is easy to shape.
  • 3. ‘GRLN01’ exhibits foliage that is glossy, fine and green in color.
  • 4. ‘GRLN01’ exhibits clean foliage with no disease problems.

The parent plant, ‘Red Tips’, differs from ‘GRLN01’ in having new shoots that are burgundy in color and less branching with less dense foliage. ‘GRLN01’ can also be compared to the Lonicera nitida cultivar ‘Tidy Tips’ (not patented), ‘GRLN02’, and ‘GRLN03’. ‘Tidy Tips’ differs from ‘GRLN01’ in having a slower growing habit, new shoots that are bronze in color, winter foliage that is red in color, and leaves that are smaller in size. ‘GRLN02’ differs from ‘GRLN01’ in having foliage that is dark green in color with new shoots that are purple in color. ‘GRLN03’ differs from ‘GRLN01’ in having new foliage shoots that are orange-brown in color.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrates the overall appearance and distinct characteristics of the new Lonicera. The photographs were taken of a 7-month-old plant of the new cultivar as grown outdoors in a 17-cm container in Wernhout, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘GRLN01’.

The photograph in FIG. 2 is provides a side view of the branches and foliage of ‘GRLN01’.

The photograph in FIG. 3 is provides a close-up view of the leaves of ‘GRLN01’.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Lonicera.
