Abstract
A distinctive cultivar of Scaevola plant named Blue Shamrock, characterized by its low-growing, compact and outwardly spreading growth habit; short internodes, dense and bushy plant form and freely branching plant habit; fluoriferousness with about 150 flowers and flower buds per plant; and large blue-purple fan-shaped flowers.
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 Blue Shamrock.
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 1993 of a proprietary selection of Scaevola aemula identified as 93/203 as the female, or seed, parent and an unidentified selection of Scaevola aemula as the male, or pollen, parent. 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 in 1993.
Compared to plants of the female parent, the selection 93/203, plants of the new Scaevola have darker green leaves that are less serrated and have shorter internodes.
Compared to plants of the male parent, the unidentified selection of Scaevola aemula, plants of the new Scaevola have larger darker green leaves and longer stems.
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 temperaure, 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 ‘Blue Shamrock’ which distinguish ‘Blue Shamrock’ as a new and distinct cultivar:
1. Low-growing, compact and outwardly spreading growth habit.
2. Short internodes, dense and bushy plant form and freely branching plant habit.
3. Freely flowering, about 150 flowers and flower buds per plant.
4. Large blue-purple fan-shaped flowers.
Compared to plants of the Scaevola aemula cultivar Blue Wonder, disclosed in U.S. Plant Pat. No. 7,929, plants of the new Scaevola are more compact, fuller, denser, and have shorter internodes when grown side-by-side.
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 top perspective view of a typical hanging basket plant of ‘Blue Shamrock’.
The photograph at the bottom of the sheet comprises a close-up view of a typical flowering stem, flower bud and open flower of plants of ‘Blue Shamrock’ (top) and upper surfaces of leaves 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 25-cm hanging basket containers with three plants each of the new cultivar grown in Bonsall, Calif. under outdoor, full-sun conditions with day temperatures ranging from 18 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.
