plant named ‘Balbahset’

Abstract

A new and distinct cultivar of Tecoma plant named ‘Balbahset’, characterized by its dark greyed-orange colored flowers, dark green-colored foliage, and moderately vigorous, upright growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Tecoma stans.

Variety denomination: ‘Balbahset’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Tecoma plant botanically known as Tecoma stans and hereinafter referred to by the cultivar name ‘Balbahset’.

The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during March 2015. The objective of the breeding program was the development of Tecoma cultivars having early continuous flowering and upright, well-branched habits.

The new Tecoma cultivar is the result of self-pollination of the proprietary Tecoma stans breeding selection coded 19555, not patented, characterized by its medium orange-colored flowers, dark green-colored foliage, and moderately vigorous, upright growth habit. The new cultivar was selected as a single flowering plant within the progeny of the above stated self-pollination during September 2016 in a controlled environment in Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since September 2016 in Arroyo Grande, Calif. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balbahset’ as a new and distinct cultivar of Tecoma plant:

• • 1. Dark greyed-orange colored flowers;
  • 2. Dark green-colored foliage; and
  • 3. Moderately vigorous, upright growth habit.

Plants of the new cultivar differ from plants of the parent primarily in having darker orange-colored flowers, more branches per plant, and more inflorescences per plant.

Of the many commercially available Tecoma cultivars, the most similar in comparison to the new cultivar is Bahama Yellow Orange ‘Balbahelor’, U.S. Plant Pat. No. 30,633. However, in comparison, plants of the new cultivar differ from plants of ‘Balbahelor’ in at least the following characteristic:

• • 1. Plants of the new cultivar have greyed-orange colored petal lobes unlike the yellow-colored petal lobes of plants of ‘Balbahelor’;
  • 2. Plants of the new cultivar have a darker greyed-orange colored corolla tube than plants of ‘Balbahelor’; and
  • 3. Plants of the new cultivar have a smaller corolla, as measured by depth and diameter, than plants of ‘Balbahelor’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balbahset’. The plants were approximately 27 weeks old and were grown for approximately 15 weeks in an outdoor nursery in Buellton, Calif.

FIG. 2 illustrates a close-up view of an individual flower of ‘Balbahset’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in September 2019 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe approximately 27-week-old plants produced from cuttings taken from stock plants. Cuttings were direct stuck in 2-inch pots and given one pinch four weeks after sticking. Plants and were grown for 12 weeks before transplant into an outdoor nursery in Buellton, Calif. Plants were then grown for approximately 15 weeks. Measurements and numerical values represent averages of typical plants.
