Abstract

A new and distinct cultivar of Evolvulus plant named ‘USEVO1201’, characterized by its compact, upright, outwardly spreading and mounding plant habit; freely branching growth habit; dense and bushy appearance; early and freely flowering habit; long flowering period; violet blue-colored flowers; and good garden performance.

Description

Botanical designation: Evolvulus hybrida.

Cultivar denomination: ‘USEVO1201’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Evolvulus plant, botanically known as Evolvulus hybrida and hereinafter referred to by the name ‘USEVO1201’.

The new Evolvulus 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 compact Evolvulus plants with uniformly mounding plant habit, long flowering period and good garden performance.

The new Evolvulus plant originated from a cross-pollination made by the Inventor on Jul. 15, 2007 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Evolvulus hybrida identified as code name 06E-22, not patented, as the female, or seed, parent with a proprietary seedling selection of Evolvulus hybrida identified as code name 05E, not patented, as the male, or pollen, parent. The new Evolvulus 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 May 23, 2008.

Asexual reproduction of the new Evolvulus plant by terminal cuttings in a controlled environment in Bonsall, Calif. since May 23, 2008 has shown that the unique features of this new Evolvulus plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Evolvulus have not been observed under all possible environmental conditions and various cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘USEVO1201’. These characteristics in combination distinguish ‘USEVO1201’ as a new and distinct Evolvulus plant:

• • 1. Compact, upright, outwardly spreading and mounding plant habit.
  • 2. Freely branching growth habit; dense and bushy appearance.
  • 3. Early and freely flowering habit.
  • 4. Long flowering period.
  • 5. Violet blue-colored flowers.
  • 6. Good garden performance.

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

• • 1. Plants of the new Evolvulus are more mounding than plants of the female parent selection.
  • 2. Plants of the new Evolvulus flower earlier than plants of the female parent selection.

The new Evolvulus plant can be compared to plants of the male parent selection. Plants of the new Evolvulus differ primarily from plants of the male parent selection in flower size as plants of the new Evolvulus have larger flowers than plants of the male parent selection.

Plants of the new Evolvulus can be compared to plants of the Evolvulus ‘American Blue’, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Evolvulus differed primarily from plants of ‘American Blue’ in the following characteristics:

• • 1. Plants of the new Evolvulus were more compact and mounding than plants of ‘American Blue’.
  • 2. Plants of the new Evolvulus flowered earlier than plants of ‘American Blue’.

Plants of the new Evolvulus can also be compared to plants of the Evolvulus ‘Hawaiian Blue Eyes’, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Evolvulus differed primarily from plants of ‘Hawaiian Blue Eyes’ in the following characteristics:

• • 1. Plants of the new Evolvulus were more compact and mounding than plants of ‘Hawaiian Blue Eyes’.
  • 2. Plants of the new Evolvulus were more freely branching than plants of ‘Hawaiian Blue Eyes’.
  • 3. Plants of the new Evolvulus flowered earlier than plants of ‘Hawaiian Blue Eyes’.
