Abstract
A new and distinct cultivar of Curcuma plant named ‘Curhonimp’, characterized by its upright plant habit with outwardly arching leaves; moderately vigorous growth habit; freely clumping growth habit; relatively broad leaves; freely flowering habit; and inflorescences with white and light purple-colored upper flower bracts with yellow green-colored apices positioned above the foliar plane on strong and erect peduncles.
Description
Botanical designation: Curcuma alismatifolia.
Cultivar denomination: ‘CURHONIMP’.
The present invention relates to a new and distinct cultivar of Curcuma plant, botanically known as Curcuma alismatifolia and hereinafter referred to by the name ‘Curhonimp’.
The new Curcuma plant is a product of a controlled breeding program conducted by the Inventor in Naaldwijk, The Netherlands. The objective of the breeding program is to create new Curcuma plants that have uniform plant habit, good container performance and attractive inflorescence coloration.
The new Curcuma is a naturally-occurring whole plant mutation of Curcuma alismatifolia ‘Curhonibo’, not patented. The new Curcuma plant was discovered and selected by the Inventor as a single flowering plant within a population of plants of ‘Curhonibo’ in a controlled greenhouse environment in Naaldwijk, The Netherlands in June, 2016.
Asexual reproduction of the new Curcuma plant by axillary bud meristem culture in a controlled environment in Naaldwijk, The Netherlands since July, 2016 has shown that the unique features of this new Curcuma plant are stable and reproduced true to type in successive generations of asexual reproduction.
Plants of the new Curcuma have not been observed under all possible combinations of environmental conditions and 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 ‘Curhonimp’. These characteristics in combination distinguish ‘Curhonimp’ as a new and distinct Curcuma plant:
-
- 1. Upright plant habit with outwardly arching leaves.
- 2. Moderately vigorous growth habit.
- 3. Freely clumping growth habit.
- 4. Relatively broad leaves.
- 5. Freely flowering habit.
- 6. Inflorescences with white and light purple-colored upper flower bracts with yellow green-colored apices positioned above the foliar plane on strong and erect peduncles.
Plants of the new Curcuma differ from plants of the mutation plant, ‘Curhonibo’, in the following characteristics:
-
- 1. Plants of the new Curcuma are more freely clumping than plants of ‘Curhonibo’.
- 2. Plants of the new Curcuma have more upper flower bracts as plants of ‘Curhonibo’.
- 3. Plants of the new Curcuma have white to light purple- colored upper flower bracts whereas plants of ‘Curhonibo’ have light blue violet-colored upper flower bracts.
Plants of the new Curcuma can also be compared to plants of Curcuma alismatifolia ‘Curalimei’, disclosed in U.S. Plant Pat. No. 25,124. In side-by-side comparisons plants of the new Curcuma differ from plants of ‘Curalimei’ in the following characteristics:
-
- 1. Plants of the new Curcuma are more freely clumping than plants of ‘Curalimei’.
- 2. Leaves of plants of the new Curcuma are broader than leaves of plants of ‘Curalimei’.
- 3. Plants of the new Curcuma have yellow green and greyed purple-colored lower flower bracts whereas plants of ‘Curalimei’ have green-colored lower flower bracts.
The accompanying photographs illustrate the overall appearance of the new Curcuma 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 colors of the new Curcuma plant.
The photograph on the first sheet is a side perspective view of a typical plant of ‘Curhonimp’ grown in a container.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Curhonimp’.
The aforementioned photographs and following observations and measurements describe plants grown during the spring in 13-cm containers in a glass-covered greenhouse in Naaldwijk, The Netherlands and under cultural practices typical of commercial Curcuma production. During the production of the plants, day temperatures ranged from 22° C. to 25° C., night temperatures ranged from 20° C. to 22° C. and light levels averaged 55 kilolux. Plants were 14 weeks old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
