Abstract
A new cultivar of Ulmus tree named ‘DavesStraightUp’ that is characterized by its upright and very columnar plant habit, its small leaves, its branch tips that are upright and do not splay with age, its strong crotch angles that are tight and average between 20° and 25° to vertical, its exfoliating bark that tends to curl in strips and reveals colorful patches of orange-tan, grey and white, its fall foliage that turns to yellow and yellow-orange in color and lasts late into the season, and its resistance to Dutch elm disease and phloem neurosis.
Description
Botanical classification: Ulmus parvifolia.
Variety denomination: ‘DavesStraightUp’.
The present invention relates to a new and distinct cultivar of Ulmus parvifolia, and will be referred to hereafter by its cultivar name, ‘DavesStraightUp’. ‘DavesStraightUp’ is a new cultivar of Chinese elm, a deciduous tree grown for use as a landscape plant.
The new Ulmus was discovered as a chance seedling from seeds sown of unnamed plants of Ulmus parvifolia in Galena, Ohio in 2001.
Asexual propagation of the new cultivar was first accomplished by grafting in 2010 by the Inventor in Galena, Ohio. Asexual propagation by grafting and budding has determined that the characteristics of the new cultivar are 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. These attributes in combination distinguish ‘DavesStraightUp’ as a unique cultivar of Ulmus.
- 1. ‘DavesStraightUp’ exhibits an upright and very columnar plant habit.
- 2. ‘DavesStraightUp’ exhibits small leaves.
- 3. ‘DavesStraightUp’ exhibits branch tips that are upright and do not splay with age.
- 4. ‘DavesStraightUp’ exhibits strong crotch angles that are tight and average between 20° and 25° to vertical.
- 5. ‘DavesStraightUp’ exhibits exfoliating bark that tends to curl in strips and reveals colorful patches of orange-tan, grey and white.
- 6. ‘DavesStraightUp’ exhibits fall foliage that turns to yellow and yellow-orange in color and lasts late into the season.
- 7. ‘DavesStraightUp’ exhibits resistance to Dutch elm disease and phloem neurosis.
Typical plants of the parent species differs from ‘DavesStraightUp’ in having a wider canopy spread, vase shaped plant habit, fall color that ranges from dull brown to bright red, variable bark exfoliation and leaves that are larger in size. ‘DavesStraightUp’ can be most closely compared to the Ulmus parvifolia cultivars ‘BSNUPF’ (U.S. Plant Pat. No. 17,655) and ‘Emer II’ (U.S. Plant Pat. No. 7,552). ‘BSNUPF’ is similar to ‘DavesStraightUp’ in having a narrow plant habit when young, dark green leaves that are smaller in size and patches of color when bark exfoliates. ‘BSNUPF’ differs from ‘DavesStraightUp’ in having a plant habit that broadens and does not retain a tight columnar plant habit, branch tips that splay outwards and leaves that are larger in size. ‘Emer II’ is similar to ‘DavesStraightUp’ in having an upright plant habit and exfoliating bark. ‘Emer II’ differs from ‘DavesStraightUp’ in having a vase-shaped habit with arching branches and a larger plant size.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Ulmus. The photographs were taken of an 18-year-old tree of ‘DavesStraightUp’ as grown outdoors in a trial bed in Galena, Ohio.
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 detailed description of 3-year-old tree of ‘DavesStraightUp’ as grown outdoors in a 3-gallon container in Galena, Ohio with mature bark and size described from an 18-year-old tree grown outdoors in a trial plot in Galena, Ohio. 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 2015 Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
