Abstract
‘VALCOSTA2’ is a new and distinctive Ctenanthe plant which is characterized by foliage with large laminae borne on long, upright petioles that arise directly from the base of the plant, a light greyed-green adaxial laminar surface with broad portions of the lamina adjacent to veins prominently colored with a mixture of dark green to yellow-green, an abaxial laminar surface which is colored with a mixture of dark greyed-purple and brown and lightly suffused with yellow-green at the margins, and the stability of all characteristics from generation to generation. The new variety is typically produced as an indoor ornamental plant.
Description
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Ctenanthe oppenheimiana.
Variety denomination: The inventive variety of Ctenanthe disclosed herein has been given the variety denomination ‘VALCOSTA2’.
This application claims priority to the Community Plant Variety Rights application number 2021/2548, filed Oct. 11, 2021, which is herein incorporated by reference.
Parentage: The claimed plant originated as a naturally occurring, whole-plant mutation. In May of 2017, the inventor discovered a plurality of whole-plant mutations at his commercial greenhouse in Maasland, the Netherlands, growing amongst a cultivated population of Ctenanthe oppenheimiana ‘Compactstar’ (not patented) plants. The newly discovered plants were isolated for further observation in order to confirm the distinctness and stability of the characteristics first observed. After further evaluation it was determined that one plant, in particular, exhibited unique foliage coloration and a growth habit that would prove favorable for commercial marketability. The new variety was given the denomination ‘VALCOSTA2’.
Asexual Reproduction: Asexual reproduction of ‘VALCOSTA2’, by way of leaf cuttings, was first performed in May of 2017 at the inventor's commercial greenhouse in Maasland, the Netherlands. ‘VALCOSTA2’ was subsequently reproduced by way of meristematic tissue culture as well. Eighteen successive generations so produced have shown that the unique features of the instant cultivar are stable and reproduced true to type.
The cultivar ‘VALCOSTA2’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in the instant environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Ctenanthe cultivar ‘VALCOSTA2’. These traits, in combination, distinguish ‘VALCOSTA2’ as a new and distinct cultivar.
-
- 1. Ctenanthe ‘VALCOSTA2’ exhibits foliage with large laminae borne on long, upright petioles that arise directly from the base of the plant; and
- 2. Ctenanthe ‘VALCOSTA2’ exhibits greyed-green to yellow-green petioles that are strongly suffused with greyed-purple on the abaxial surface; and
- 3. Ctenanthe ‘VALCOSTA2’ exhibits an adaxial laminar surface which is colored light greyed-green, with broad portions of the lamina adjacent to veins prominently colored with a mixture of green to yellow-green, creating a unique color pattern; and
- 4. Ctenanthe ‘VALCOSTA2’ exhibits an abaxial laminar surface which is colored with a mixture of dark greyed-purple and brown and lightly suffused with yellow-green at the margins.
The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
The following observations and measurements made in October of 2021 describe averages from a sample set of six specimens of 1 year old ‘VALCOSTA2’ plants grown in 17 cm nursery containers at commercial greenhouse in Maasland, the Netherlands. Plants were produced using conventional greenhouse production protocols for Ctenanthe which consisted of growing under shade cloth, regular overhead irrigation, and fertilizer applications as needed. No chemical pest and disease control measures were taken. No photoperiodic treatments or artificial light was given to the plants.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘VALCOSTA2’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such measurements are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, Sixth Edition.
