plant named ‘Sungelobu’

Abstract

A new and distinct cultivar of Angelonia plant named ‘Sungelobu’, characterized by its compact and upright plant habit; freely branching habit; freely flowering habit; long flowering period; large purple violet-colored flowers; and good garden performance.

Description

Botanical designation: Angelonia augustifolia.

Cultivar denomination: ‘SUNGELOBU’.

BACKGROUND OF THE INVENTION

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

The new Angelonia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact, upright and freely branching Angelonia plants with attractive flower coloration.

The new Angelonia plant originated from a cross-pollination made by the Inventor in August, 2006 in Higashiomi, Shiga, Japan of a proprietary selection of Angelonia angustifolia identified as code number AA-04, not patented, as the female, or seed, parent with a proprietary selection of Angelonia angustifolia identified as code number A120-3, not patented, as the male, or pollen, parent. The new Angelonia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in August, 2007.

Asexual reproduction of the new Angelonia plant by cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since September, 2007, has shown that the unique features of this new Angelonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Angelonia 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 ‘Sungelobu’. These characteristics in combination distinguish ‘Sungelobu’ as a new and distinct Angelonia plant:

• • 1. Compact and upright plant habit.
  • 2. Freely branching habit.
  • 3. Freely flowering habit.
  • 4. Long flowering period.
  • 5. Large purple violet-colored flowers.
  • 6. Good garden performance.

Plants of the new Angelonia differ from plants of the female parent selection primarily in plant habit as plants of the new Angelonia are more compact than plants of the female parent selection. In addition, plants of the new Angelonia and the female parent selection differ in flower color as plants of the female parent selection have white-colored flowers.

Plants of the new Angelonia differ from plants of the male parent selection primarily in plant habit as plants of the new Angelonia are more compact than plants of the male parent selection. In addition, plants of the new Angelonia and the male parent selection differ in flower color as plants of the male parent selection have light pink-colored flowers.

Plants of the new Angelonia can be compared to plants of Angelonia angustifolia ‘Cart Pur’, disclosed in U.S. Plant Pat. No. 15,285. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Angelonia and ‘Cart Pur’ differed in the following characteristics:

• • 1. Plants of the new Angelonia were more upright and narrower than plants of ‘Cart Pur’.
  • 2. Plants of the new Angelonia had larger leaves than plants of ‘Cart Pur’.
  • 3. Plants of the new Angelonia and ‘Cart Pur’ differed slightly in flower color.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and the following observations, measurements and values were grown during the summer and autumn in 15-cm containers in a polyethylene-covered greenhouse in Higashiomi, Shiga, Japan and under typical commercial cultural practices. During the production of the plants, day temperatures averaged 22° C. and night temperatures averaged 15° C. Plants were four months old when the photographs and the description were taken.
