Abstract

A new and distinct cultivar of Impatiens walleriana plant named ‘TiRow’ characterized by large pink bi-colored fully double flowers, flowers that are positioned above or beyond the foliage, good heat tolerance, dark green foliage and mounded, freely branching and dense plant habit.

Description

BACKGROUND—FIELD OF INVENTION
The present invention relates to a new and distinct cultivar botanically known as Impatiens walleriana, and by the cultivar name ‘TiRow’.
The cultivar of the photograph was developed and selected in a controlled breeding program in a controlled environment in Broadbent, Oreg. by the inventors, Harlan Cosner and Sue Cosner, as described herein.
BACKGROUND—DESCRIPTION OF THE PRIOR ART
The closest known cultivar of prior art is named ‘Sparkler Rose’, subject of U.S. Plant Pat. No. 9,603.
COMPARISON
The impatiens plant of the present invention differs from prior plants, namely ‘Sparkler Rose’ in at least the following ways:
1. The plant of the present invention has been shown to perform better in the heat than ‘Sparkler Rose’;
2. The flowers of the present invention are much larger, generally a full centimeter, than the flowers of ‘Sparkler Rose’;
3. The flower colors of ‘Sparkler Rose’ tend to bleed into each other while the flower colors of the present invention have a clear division between the pink and the whitish colors; and
4. The foliage of the present invention is darker green than the foliage of ‘Sparkler Rose’.
These and other characteristics will be apparent to persons skilled in the art.
BACKGROUND—DISCOVERY
The present cultivar was developed by standard cross-pollination. Its seed parent is a semi-double impatiens plant with large hot pink flowers. This plant was designated B-9X-1377 under the inventors' controlled breeding program. The pollen parent is a pollen-producing double impatiens plant with purple and white bi-colored flowers. This plant was designated B-9X-237 under the inventors' controlled breeding program. The parent plants are not the subject of any granted patent or pending application. The cross was made in the inventors' controlled breeding program, and the first asexual reproduction was made at Broadbent, Oreg. Successive asexually reproduced generations have shown the present invention to be stable. Each asexually reproduced generation has been accomplished using lateral stems with leaves.
The traits of the cultivar of the present invention that have been observed in each successive generation of asexual reproduction, and which are unique, are the large pink bi-colored fully double flowers, flowers that are positioned above or beyond the foliage, good heat tolerance, dark green foliage and mounded, freely branching and dense plant habit and both male and female sterility.
Color references are according to The Royal Horticultural Society Colour Chart, except where general terms of ordinary dictionary significance are used.
DETAILED DESCRIPTION
The following observations, measurements and description of the plants and flowers are based on the environmental and cultural practices at Broadbent, Oreg. The following measurements, values and comparisons describe plants grown under a double layer of polyethylene film with temperatures typically ranging from about 55° F. to about 85° F. during the daytime. Night heat was provided by bench top set at 62° F. The individual plants were grown in six-inch Azalea containers in a soiless medium. Plants were liquid fed with high nitrate plus trace elements applied at N level 150 PPM of two successive feedings followed by one leaching with clear water. Plants started in the last week of June and finished in late September. Light levels were between 4,000 and 6,000 ft. candles.
The plant of the present invention has not been observed in all possible environmental and/or cultural conditions. The phenotype may vary significantly with variations in environment such as temperature, light level, humidity and also with cultural practices such as fertility, soil and water quality.
The accompanying photograph illustrates the overall appearance and the flower color of the cultivar of the present invention described herein. The photograph was taken of a mature plant 14 weeks of age and during full inflorescence. There may be variations between the colors in the photograph and the colors in the following description due to, for example, light reflectance, or the amount of blue or red light captured in the film. If such variations occur, the written description shall control.

Disease resistance.—The instant plant has shown good resistance to botrytis.
Rooting ability.—Easy, no hormones are needed.
Cold/heat resistance.—Plants of the present invention and ‘Sparkler Rose’ were grown side by side under shade cloth at Alva, Fla. during late spring through July. The day temperature was in the mid 90° F. range. ‘Sparkler Rose’ remained small and lacked vigor or strength, the flower color appeared smoky, while ‘TiRow’ grew strong, had large flowers and the colors were clear and bright.
Dampness resistance.—Outdoors during rainy weather at Broadbent, Oreg., ‘Sparkler Rose’ showed weakness in its peduncles and pedicels which caused the flowers to droop or face down during rains. Even after rains, the flowers of ‘Sparkler Rose’ that drooped during rains remained drooped or face down until they were shed. In comparison, the flowers of ‘TiRow’ remained face up or out and seldom drooped during rainy weather.
