Abstract
A new and distinct cultivar of Clethra plant named ‘Caleb’, characterized by its upright and somewhat outwardly spreading plant habit; vigorous growth habit; freely branching habit; dark-green leaves; large inflorescences with numerous large flowers; and good garden performance.
Description
Botanical designation: Clethra alnifolia.
Cultivar denomination: ‘Caleb’.
The present invention relates to a new and distinct cultivar of Clethra plant, botanically known as Clethra alnifolia and hereinafter referred to by the name ‘Caleb’.
The new Clethra plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program is to develop new Clethra cultivars with large inflorescences flowers.
The new Clethra plant originated from an open-pollination in August, 2003 of Clethra alnifolia ‘Ruby Spice’, not patented, as the female, or seed, parent with an unknown selection of Clethra alnifolia, as the male, or pollen, parent. The new Clethra plant was discovered and selected by the Inventor in August, 2005 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.
Asexual reproduction of the new Clethra plant by softwood cuttings in a controlled greenhouse environment in Grand Haven, Mich. since the spring of 2006 has shown that the unique features of this new Clethra plant are stable and reproduced true to type in successive generations of asexual reproduction.
Plants of the new Clethra have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Caleb’. These characteristics in combination distinguish ‘Caleb’ as a new and distinct cultivar of Clethra:
-
- 1. Upright and somewhat outwardly spreading plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit.
- 4. Dark-green leaves.
- 5. Large inflorescences with numerous large flowers.
- 6. Good garden performance.
Plants of the new Clethra can be compared to plants of the female parent, ‘Ruby Spice’. Plants of the new Clethra differ from plants of ‘Ruby Spice’ in the following characteristics:
-
- 1. Plants of the new Clethra have larger inflorescences than plants of ‘Ruby Spice’.
- 2. Plants of the new Clethra have larger flowers than plants of ‘Ruby Spice’.
- 3. Plants of the new Clethra have white-colored flowers whereas plants of ‘Ruby Spice’ have pink-colored flowers.
Plants of the new Clethra can be compared to plants of the Clethra alnifolia ‘Hummingbird’, not patented. In side-by-side comparisons conducted in Grand Haven, Mich., plants of the new Clethra differed from plants of ‘Hummingbird’ in the following characteristics:
-
- 1. Plants of the new Clethra were larger than plants of ‘Hummingbird’.
- 2. Plants of the new Clethra have larger inflorescences than plants of ‘Hummingbird’.
- 3. Plants of the new Clethra have larger flowers than plants of ‘Hummingbird’.
The accompanying colored photographs illustrate the overall appearance of the new Clethra plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. 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 Clethra plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘Caleb’ grown in a container.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Caleb’.
The aforementioned photographs and following observations, measurements and values describe plants grown in one-gallon containers in Grand Haven, Mich. during the spring and early summer in an outdoor nursery and under conditions which closely approximate commercial production. Plants were two years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
