Botanical classification: Laurus nobilis.
Cultivar designation: ‘GREAWL’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Laurus nobilis and will be referred to hereafter by its cultivar name, ‘GREAWL’. ‘GREAWL’ is a new cultivar of bay laurel; an evergreen shrub grown for use as a landscape plant.
The new cultivar originated as a chance seedling that was discovered in a container block that had been planted with open pollinated seeds of an unnamed and unpatented plant of Laurus nobilis in 2019 in El Campo, Texas. The male parent is therefore unknown.
Asexual propagation of the new cultivar was first accomplished by the Inventor by semi-hardwood cuttings in April of 2021 in El Campo, Texas. Asexual propagation of the new cultivar by semi-hardwood stem 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 ‘GREAWL’ as a new and unique cultivar of Laurel.
•
• 1. ‘GREAWL’ exhibits scalloped leaf margins creating a wavy foliage appearance. • 2. ‘GREAWL’ exhibits a range of leaf colors; emerging red, changing to bronze and maturing to dark green. • 3. ‘GREAWL’ exhibits short internodes creating a compact plant habit. • 4. ‘GREAWL’ exhibits good self-branching creating a dense and full appearance. • 5. ‘GREAWL’ exhibits foliage with strong and sweet aromas of cinnamon and cloves.
The female parent of ‘GREAWL’ differs from ‘GREAWL’ in having leaf margins that are entire leaf margins, more smooth and flat leaf orientation, longer internodes, a less compact, more upright and less full plant habit, less self-branching, and young foliage that emerges mint green in color. ‘GREAWL’ can be most closely compared to the Laurus nobilis cultivars ‘Crestwood’ (not patented) and ‘Willow Leaf’ (not patented). ‘Crestwood’ is similar to ‘GREAWL’ in having dark green mature foliage. ‘Crestwood’ differs from ‘GREAWL’ in having leaves that are rounder in shape and flatter in aspect with smoother margins, and in having a larger plant size. ‘Willow Leaf’ is similar to ‘GREAWL’ in having short internodes with a compact plant habit. ‘Willow Leaf’ differs from ‘GREAWL’ in having leaves that are lighter green in color and more narrow with smoother margins, a larger plant size, a faster growth rate, and leaves that are less fragrant when crushed.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color photographs illustrate the overall appearance and distinct characteristics of the new Laurel . The photographs were taken of a plant 6 years in age of the new cultivar as grown outdoors in a 15-gallon container in El Campo, Texas.
The photograph in FIG. 1 provides a side view of the plant of ‘GREAWL’.
The photograph in FIG. 2 provides a close-up view of the young foliage of ‘GREAWL’.
The photograph in FIG. 3 provides a close-up view of the mature foliage of ‘GREAWL’.
The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Laurel.
DETAILED BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of 2.5 year-old plants of the new cultivar as grown outdoors in 3-gallon containers in Park Hill, Oklahoma.
