Abstract

A new and distinct cultivar of Heliotrope plant named ‘USHTRP0303’, characterized by its upright to outwardly spreading plant habit; vigorous growth habit; freely branching habit; freely flowering habit; fragrant violet-colored flowers; and good summer garden performance.

Description

Botanical designation: Heliotropium amplexicaule×Heliotropium leiocarpum.
Cultivar denomination: ‘USHTRP0303’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Heliotrope plant, botanically known as Heliotropium amplexicaule×Heliotropium leiocarpum and hereinafter referred to by the name ‘USHTRP0303’.
The new Heliotrope plant is a product of a planned breeding program conducted by the Inventor in Hikone, Shiga, Japan. The objective of the breeding program is to create new Heliotrope cultivars with good plant habit and attractive coloration.
The new Heliotrope plant originated from a cross-pollination made by the Inventor on Jun. 18, 2002 of Heliotropium amplexicaule ‘Azure Skies’, not patented, as the female, or seed, parent with and unnamed selection of Heliotropium leiocarpum, not patented, as the male, or pollen, parent. The new Heliotrope plant was discovered and selected by the Inventor as a single flowering plant with the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Hikone, Shiga, Japan on Jul. 14, 2003.
Asexual reproduction of the Heliotrope plant by vegetative cuttings in Hikone, Shiga, Japan since Jul. 14, 2003, has shown that the unique features of this new Heliotrope plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Heliotrope have 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 ‘USHTRP0303’. These characteristics in combination distinguish ‘USHTRP0303’ as a new and distinct cultivar of Heliotrope:
    • 1. Upright to outwardly spreading plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Fragrant violet-colored flowers.
    • 6. Good summer garden performance.
Plants of the new Heliotrope differ from plants of the female parent, ‘Azure Skies’, in the following characteristics:
    • 1. Plants of the new Heliotrope are more mounding than and not as creeping as plants of ‘Azure Skies’.
    • 2. Plants of the new Heliotrope have darker-colored flowers than plants of ‘Azure Skies’.
    • 3. Flowers of plants of the new Heliotrope are more fragrant than plants of ‘Azure Skies’.
Plants of the new Heliotrope differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Heliotrope are more freely branching than plants of the male parent selection.
    • 2. Plants of the new Heliotrope have smaller leaves than plants of the male parent selection.
Plants of the new Heliotrope can be compared to plants of Heliotrope ‘Atlanta’, disclosed in U.S. Plant Pat. No. 11,326. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Heliotrope differed from plants of ‘Atlanta’ in the following characteristics:
    • 1. Plants of the new Heliotrope were more vigorous than and not as compact as plants of ‘Atlanta’.
    • 2. Flowers of plants of the new Heliotrope had yellow green-colored centers whereas flowers of plants of ‘Atlanta’ had purple-colored centers.
    • 3. Flowers of plants of the new Heliotrope were more fragrant than flowers of plants of ‘Atlanta’.
Plants of the new Heliotrope can also be compared to plants of Heliotrope ‘Nagano’, disclosed in U.S. Plant Pat. No. 14,077. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Heliotrope differed from plants of ‘Nagano’ in the following characteristics:
    • 1. Plants of the new Heliotrope had lighter-colored flowers than plants of ‘Nagano’.
    • 2. Flowers of plants of the new Heliotrope had yellow green-colored centers whereas flowers of plants of ‘Nagano’ had purple-colored centers.
    • 3. Flowers of plants of the new Heliotrope were more fragrant than flowers of plants of ‘Nagano’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Heliotrope plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Heliotrope plant.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘USHTRP0303’ grown in a container.
The photograph at the top of the sheet is a close-up view of typical flowers and leaves of ‘USHTRP0303’.
 DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the autumn in 12.5-cm containers in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures ranged from 18° C. to 38° C., night temperatures ranged from 9° C. to 18° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched one time and were seven weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
