Abstract
A new and distinct Dracaena plant named ‘DRAWHISPI’ which is characterized by thick, durable foliage that is held nearly vertical on a short, unbranched stem, green foliage that is blotched and axially striped with greyed-green and white, foliage that is broadly, axially striped with white along the marginal zones of the foliage, and the stability of these characteristics from generation to generation.
Description
Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Dracaena fragrans.
Variety denomination: The inventive cultivar of Dracaena disclosed herein has been given the variety denomination ‘DRAWHISPI’.
Parentage: ‘DRAWHISPI’ is a spontaneous branch-plant mutation of a Dracaena fragrans ‘White Jewel’ plant (U.S. Plant Pat. No. 12,433) which was discovered at a commercial greenhouse in Honselersdijk, the Netherlands in May of 2010. The mutation was initially noted for its abundance of upright, variegated foliage. Said mutation was isolated for further evaluation to confirm the uniformity and stability of the unique characteristics first observed. Upon confirmation of the stability and uniformity of the characteristics, the new plant was selected for commercialization.
Asexual Reproduction: Asexual reproduction of ‘DRAWHISPI’ is accomplished by way of rooting stem cuttings. Propagation was first performed in May of 2010 at the inventor's commercial greenhouse in Honselersdijk, the Netherlands. Through five subsequent generations, the unique features of this cultivar have proven to be stable and true to type.
The cultivar ‘DRAWHISPI’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘DRAWHISPI’. These characteristics in combination distinguish ‘DRAWHISPI’ as a new and distinct Dracaena fragrans cultivar:
-
- 1. Dracaena ‘DRAWHISPI’ exhibits foliage that is held nearly vertical on a short, unbranched stem; and
- 2. Dracaena ‘DRAWHISPI’ exhibits thick, durable foliage with a smooth laminar surface; and
- 3. Dracaena ‘DRAWHISPI’ exhibits green foliage that is blotched and axially striped with greyed-green and white; and
- 4. Dracaena ‘DRAWHISPI’ exhibits foliage that is broadly, axially striped with white along the marginal zones of the foliage.
The following observations and measurements, made in July of 2022, describe averages from a sample set of six specimens of 12-week-old ‘DRAWHISPI’ plants grown in 15 cm nursery pots in San Jose, Costa Rica. Plants were produced using conventional greenhouse production protocols for Dracaena sp. which consisted of growing under shade cloth, regular overhead irrigation, and chemical control of thrips insects. 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. ‘DRAWHISPI’ 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 characteristics 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, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
A botanical description of ‘DRAWHISPI’ and comparisons with the parent plant and most similar commercial Dracaena cultivar known to the inventor are provided below.
