Abstract
A new cultivar of Cornus, ‘Jefreb’, that is characterized by its compact plant habit that is broader than it is tall, its stems that are narrow in diameter and densely branched, and red in color during the winter, and its foliage that is green in color.
Description
Botanical classification: Cornus alba.
Variety denomination: ‘Jefreb’.
The present invention relates to a new and distinct cultivar of Cornus, botanically known as Cornus alba ‘Jefreb’ and will be referred to hereafter by its cultivar name, ‘Jefreb’. ‘Jefreb’ is a new cultivar of red twig dogwood, a shrub grown for use as an ornamental landscape plant.
The Inventor discovered the new cultivar as naturally occurring branch mutation of the cultivar ‘Bailhalo’ (U.S. Plant Pat. No. 8,722) in his trial garden in Portage la Prairie, Manitoba, Canada, in spring 2005.
Asexual propagation of the new cultivar was first accomplished by the Inventor using stem cuttings in summer of 2006 in Portage la Prairie, Manitoba, Canada. Asexual propagation of the new cultivar by stem cuttings has been determined that the characteristics 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 ‘Jefreb’ as unique cultivar of Cornus.
-
- 1. ‘Jefreb’ exhibits a compact plant habit that is broader than it is tall.
- 2. ‘Jefreb’ exhibits stems that are narrow in diameter and densely branched.
- 3. ‘Jefreb’ exhibits stems that are red in color during the winter.
- 4. ‘Jefreb’ exhibits foliage that is medium green in color.
The parent plant of ‘Jefreb’, ‘Bailhalo’, differs from ‘Jefreb’ in having variegated foliage, in having stems that are medium in diameter and moderately branched, and in being nearly the same height and width. ‘Jefreb’ can be most closely compared to the Cornus cultivars ‘Minbat’ (not patented) and ‘Cream Cracker’ (U.S. Plant Pat. No. 12,830). ‘Minbat’ is similar to ‘Jefreb’ in having a compact growth habit and in having red stems in the winter. ‘Minbat’ differs from ‘Jefreb’ in having a more upright, rounded plant form and in having stems that are less densely branched. ‘Cream Cracker’ differs from ‘Jefreb’ in having variegated foliage that is gray-green in color with creamy white colored margins, and in being taller in height and wider in diameter.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Cornus.
The photograph of the plants in FIG. 1 was taken of five year-old plants of ‘Jefreb’ as field grown outdoors in Portage la Prairie, Manitoba, Canada and provides a view of the overall plant habit of ‘Jefreb’.
The photograph of the plants in FIG. 2 was taken of three year-old plants of ‘Jefreb’ as grown outdoors in 9-liter containers in Portage la Prairie, Manitoba, Canada and provides a comparison of the foliage of ‘Jefreb’ on the left and its parent plant, ‘Bailhalo’ on the right.
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 Cornus.
The following is a detailed description of three year-old plants the new Cornus as grown outside in 2-gallon containers in St. Paul, Minn. 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.
