Abstract

A new and distinct cultivar of Calibrachoa plant named ‘USCAL48804’, characterized by its compact, mounding and outwardly spreading plant habit; vigorous and freely branching growth habit; dense and bushy appearance; early and freely flowering habit; small light purple-colored flowers with darker purple-colored centers; and good garden and summer performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCAL48804’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘USCAL48804’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new Calibrachoa plants with uniform plant habit, freely branching growth habit, attractive small flowers and good summer performance.

The new Calibrachoa plant originated from a cross-pollination made by the Inventor on May 8, 2005 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Calibrachoa sp. identified as code number CJ05-48, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code number C377-04, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Bonsall, Calif. on Jul. 6, 2006.

Asexual reproduction of the new Calibrachoa plant by terminal cuttings in a controlled environment in Bonsall, Calif. since Jul. 10, 2006 has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa 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 ‘USCAL48804’. These characteristics in combination distinguish ‘USCAL48804’ as a new and distinct cultivar of Calibrachoa:

    • 1. Compact, mounding and outwardly spreading plant habit.
    • 2. Vigorous and freely branching growth habit; dense and bushy appearance.
    • 3. Early and freely flowering habit.
    • 4. Small light purple-colored flowers with darker purple-colored centers.
    • 5. Good garden and summer performance.

The new Calibrachoa plant can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Calibrachoa are more freely branching than plants of the female parent selection.
    • 2. Plants of the new Calibrachoa have smaller flowers than plants of the female parent selection.
    • 3. Plants of the new Calibrachoa and the female parent selection differ in flower color as plants of the female parent selection have pink-colored flowers.

The new Calibrachoa plant can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Calibrachoa are more mounding than and not as creeping as plants of the male parent selection.
    • 2. Plants of the new Calibrachoa and the male parent selection differ in flower color as plants of the male parent selection have apricot-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa ‘USCALI212-1’, disclosed in U.S. Plant Pat. No. 18,421. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed from plants of ‘USCALI212-1’ in the following characteristics:

    • 1. Plants of the new Calibrachoa were more compact than and not as vigorous as plants of ‘USCALI212-1’.
    • 2. Plants of the new Calibrachoa flowered earlier than plants of ‘USCALI212-1’.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa ‘USCALI48’, disclosed in U.S. Plant Pat. No. 15,707. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed from plants of ‘USCALI48’ in the following characteristics:

    • 1. Plants of the new Calibrachoa had smaller flowers than plants of ‘USCALI48’.
    • 2. Plants of the new Calibrachoa and ‘USCALI48’ flowered earlier than plants of ‘USCALI48’.
