Abstract
A new cultivar of Ulmus pumila, ‘Meirenyu’, characterized by its foliage that is bright yellow in color with the yellow color retained throughout the growing season on leaves with good sun exposure and by its young branches that are orange-red in color.
Description
Botanical classification: Ulmus pumila.
Variety denomination: ‘Meirenyu’.
The present invention relates to a new and distinct cultivar of Ulmus pumila, and will be referred to hereafter by its cultivar name, ‘Meirenyu’. ‘Meirenyu’ is a new cultivar of Siberian elm, deciduous tree grown for use as a landscape plant.
The new Ulmus was discovered as a whole plant mutation from seeds sown of Ulmus pumila ‘Mizhibaiyu’ (not patented) in Shijiazhuang City, China in 2001.
Asexual reproduction of the new cultivar was first accomplished by one of the Inventors by grafting in 2001 in Shijiazhuang City, China. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar as observed on seven year-old plants in Shijiazhuang City, China. These attributes in combination distinguish ‘Meirenyu’ as a unique cultivar of Ulmus.
-
- 1. ‘Meirenyu’ exhibits foliage that is yellow in color from leaf emergence to late May with the yellow color retained throughout the growing season on the outer leaves with good sun exposure.
- 2. ‘Meirenyu’ exhibits young branches that are orange-red in color.
- 3. ‘Meirenyu’ exhibits an upright habit with an elliptic-shaped canopy.
The parent plant, ‘Mizhibaiyu’ differs from ‘Meirenyu’ in having green leaves and in having young branches that are brown in color. ‘Meirenyu’ can be most closely compared to the cultivar ‘Aurea’ (syn. ‘Beijing Gold’), not patented. ‘Aurea’ is similar to ‘Meirenyu’ in having yellow foliage and young branches that are orange-red in color. ‘Aurea’ differs from ‘Meirenyu’ in having a dwarf and more narrow plant habit.
The accompanying colored photographs of ‘Meirenyu’ illustrate the overall appearance and distinct characteristics of the new Ulmus. The photographs in FIG. 1 , FIG. 2 , and FIG. 3 were taken of a plant seven years in age as grown outdoors in a field-plot in Shijiazhuang City, China.
The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Ulmus.
The following is a description of seven year-old plants of the new cultivar as field grown in Shijiazhuang City, China. The climate in Shijiazhuang City is semi-arid, with hot humid summers, cold, windy, and dry winters and natural light levels of 2,427 hours per year. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
