Abstract

A new and distinct cultivar of an ornamental Ipomoea plant named ‘Balspotimart’, characterized by shallowly-lobed, medium lime-green colored foliage, and moderately vigorous, compact, mounded-spreading growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Ipomoea batatas.

Variety denomination: ‘Balspotimart’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Ipomoea plant botanically known as Ipomoea batatas and hereinafter referred to by the cultivar name ‘Balspotimart’.

The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during October 2013. The objective of the breeding program was the development of ornamental Ipomoea cultivars with heart-shaped leaves, and a well-branched, mounded growth habit with good garden performance under high night temperatures.

The new ornamental Ipomoea cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary breeding selection BW028-023, unpatented, characterized by its medium lime-green colored foliage and moderately vigorous, compact, mounded-spreading growth habit. The male (pollen) parent of the new cultivar is the proprietary breeding selection B W009-013, unpatented, characterized by its medium lime-green colored foliage and moderately vigorous, compact, mounded- spreading growth habit. The new cultivar was discovered and selected as a single plant within the progeny of the above stated cross-pollination during April 2014 in a controlled environment in Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since April 2014 in Arroyo Grande, Calif., and West Chicago, Ill. 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 ‘Balspotimart’ as a new and distinct cultivar of Ipomoea plant:

- 1. Shallowly-lobed, medium lime-green colored foliage; and
- 2. Moderately vigorous, compact, mounded-spreading growth habit.

Plants of the new cultivar differ from plants of the female and male parents primarily in maintaining plant habit and foliage color under high sunlight conditions and high night temperatures. In addition plants of the new cultivar differ from plants of the male parent in having more shallowly-lobed foliage.

Of the many commercially available ornamental Ipomoea cultivars, the most similar in comparison to the new cultivar is Spotlight Lime, ‘Balspotime’, U.S. Plant Pat. No. 28,588. However, in comparison, plants of the new cultivar differ from plants of ‘Balspotime’ in at least the following characteristics:

- 1. Plants of the new cultivar have more shallowly-lobed foilage than plants of ‘Blaspotime’;
- 2. Plants of the new cultivar do not have branches with a greyed-purple overlay when developing like plants of ‘Balspotime’; and
- 3. Plants of the new cultivar have smaller leaves than plants of ‘Balspotime’.

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 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 ‘Balspotimart’. The plants were grown in one-gallon pots for 11 weeks in a greenhouse in Arroyo Grande, Calif.

FIG. 1 illustrates a side view of the overall growth and habit of ‘Balspotimart’.

FIG. 2 illustrates a close-up view of an individual leaf of ‘Balspotimart’.

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 March 2018 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in West Chicago, Ill. in 4-inch pots for 10 weeks in a greenhouse utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 68° F. to 72° F. (20° C. to 22° C.) during the day and approximately 64° F. to 66° F. (18° C. to 19° C.) during the night. Supplemental lighting was used. Measurements and numerical values represent averages of typical plants.
