Abstract
A distinctive cultivar of Scaevola plant named White Champ, characterized by its low-growing, spreading and cascading growth habit; short internodes; dense and bushy plant form and freely branching plant habit; freely flowering habit with more than 200 flowers and flower buds per plant; and unique large white fan-shaped flowers with yellow green throat.
Description
The present invention relates to a new and distinct cultivar of Scaevola plant, botanically known as Scaevola aemula and referred to by the cultivar name White Champ.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Emerald, Victoria, Australia. The objective of the breeding program was to create new compact Scaevola cultivars.
The new cultivar originated from a cross made by the Inventor in 1996 of two unidentified selections of Scaevola aemula. The new Scaevola was selected by the Inventor as a flowering plant within the progeny of this cross in a controlled environment in Emerald, Victoria, Australia.
Plants of the new Scaevola have white flowers whereas plants of the unidentified selections have lavender blue flowers which is typical for the species Scaevola aemula. In addition, plants of the new Scaevola have lighter green leaves than plants of the female parent.
Asexual propagation of the new cultivar by terminal cuttings taken in Emerald, Victoria, Australia, has shown that the unique features of this new Scaevola are stable and are reproduced true to type in successive propagations.
The new cultivar has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
The following characteristics have been repeatedly observed and are determined to be basic characteristics of ‘White Champ’ which distinguish ‘White Champ’ as a new and distinct cultivar:
1. Low-growing, spreading and cascading growth habit.
2. Short internodes, dense and bushy plant form and freely branching plant habit.
3. Freely flowering, more than 200 flowers and flower buds per plant.
4. Unique large white fan-shaped flowers with yellow green throat.
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The photograph at the top of the sheet comprises a side perspective view of a typical hanging basket container with three plants of ‘White Champ’.
The photograph at the bottom of the sheet comprises a close-up view of typical flowering stems and leaves of plants of ‘White Champ’ showing various stages of development and leaf shapes. Flower and foliage colors in the photographs may appear different from the actual colors due to light reflectance.
The following observations, measurements and values describe 20-cm hanging basket containers with three plants each of the new cultivar grown for 8 to 10 weeks during the summer in Bonsall, Calif., under outdoor, full-sun conditions with day temperatures ranging from 21 to 35° C. and night temperatures ranging from 13 to 18° C.
Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
