| Abstract: |
A new and distinct cultivar of Ozothamnus plant named `13-15`, characterized by its upright plant habit; vigorous growth habit; short internodes; dense and bushy habit; freely flowering habit; and inflorescences arranged in corymbs with white-colored involucral bracts. |
| Claim: |
It is claimed:
1. A new and distinct Ozothamnus plant named `13-15` as illustrated and described. |
| Description: |
Botanical designation: Ozothamnusdiosmifolius.
Cultivar denomination: `13-15`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Ozothamnus plant, botanically known as Ozothamnus diosmifolius, and hereinafter referred to by the name `13-15`.
The new Ozothamnus is a product of a planned breeding program conducted by the Inventors in Helidon, Queensland, Australia. The objective of the breeding program is to create vigorous and upright Ozothamnus cultivars with numerous and attractiveflowers.
The new Ozothamnus originated from a self-pollination made by the Inventors in Helidon, Queensland, Australia in 1993, of the Ozothamnus diosmifolius cultivar Pom Pom, not patented. The new Ozothamnus was discovered and selected by the Inventorsas a single flowering plant from within the progeny of the stated self-pollination grown in a controlled environment in Helidon, Queensland, Australia in March, 1993.
Asexual reproduction of the new Ozothamnus by vegetative cuttings in a controlled environment in Helidon, Queensland, Australia since 1994, has shown that the unique features of this new Ozothamnus are stable and reproduced true to type insuccessive generations.
SUMMARY OF THE INVENTION
The cultivar 13-15 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 `13-15`. These characteristics in combination distinguish `13-15` as a new and distinct cultivar of Ozothamnus: 1. Upright plant habit. 2. Vigorous growth habit. 3. Short internodes; dense and bushy habit. 4. Freely flowering habit. 5. Inflorescences arranged in corymbs with white-colored involucral bracts.
Plants of the new Ozothamnus differ from plants of the parent, the cultivar Pom Pom, in the following characteristics: 1. Plants of the new Ozothamnus are more upright than plants of the cultivar Pom Pom. 2. Plants of the new Ozothamnus andthe cultivar Pom Pom differ in involucral bract color as plants of the cultivar Pom Pom have pink-colored involucral bracts.
Plants of the new Ozothamnus can be compared to plants of the Ozothamnus cultivar Just Blush, not patented. In side-by-side comparisons conducted in Helidon, Queensland, Australia, plants of the new Ozothamnus differed from plants of thecultivar Just Blush in the following characteristics: 1. Plants of the new Ozothamnus were taller and more upright than plants of the cultivar Just Blush. 2. Plants of the new Ozothamnus and the cultivar Just Blush differed in involucral bract coloras plants of the cultivar Just Blush had pink-colored involucral bracts.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Ozothamnus. The photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differslightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Ozothamnus.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of `13-15` grown in a container.
The photograph at the top of the sheet is a close-up view of a typical corymb of `13-15`.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and followingobservations and measurements describe plants grown in Bonsall, Calif. during the autumn in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Ozothamnus production. During the production of theplants, day temperatures ranged from about 18.degree. C. to 38.degree. C. and night temperatures ranged from 13.degree. C. to 24.degree. C. Measurements and numerical values represent averages for typical flowering plants. Plants were about fivemonths old when the photographs and description were taken.
