Abstract
A new and distinct Dracaena plant named ‘0801BJ’ which is characterized by upright foliage born on an unbranched stem, dark green foliage with a slight axial twist, coarsely undulate foliar margins, 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 ‘0801BJ’.
Parentage: ‘0801BJ’ is a spontaneous branch-plant mutation of a Dracaena fragrans ‘Green Jewel’ (Community Plant Variety Rights grant number 11181) which was discovered at a commercial greenhouse in Honselersdijk, the Netherlands in the spring of 2008. The mutation was initially noted for its thick, dark green foliage and upright growth habit. 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 ‘0801BJ’ is accomplished by way of rooting stem cuttings. Propagation was first performed in the summer of 2008 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 ‘0801BJ’ 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 ‘0801BJ’. These characteristics in combination distinguish ‘0801BJ’ as a new and distinct Dracaena fragrans cultivar:
-
- 1. Dracaena ‘0801BJ’ exhibits upright foliage born on an unbranched stem; and
- 2. Dracaena ‘0801BJ’ exhibits relatively thick foliage; and
- 3. Dracaena ‘0801BJ’ exhibits dark green foliage with a smooth texture.
The following observations and measurements, made in February of 2021, describe averages from a sample set of six specimens of 8 week-old ‘0801BJ’ plants grown in 11 cm nursery pots in Honselersdijk, the Netherlands. Plants were produced using conventional greenhouse production protocols for Dracaena sp. which consisted of growing under shade, regular overhead irrigation and regular fertigation, 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. ‘0801BJ’ 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 ‘0801BJ’ and comparisons with the parent plant and most similar commercial Dracaena cultivar known to the inventor are provided below.

Sheath — Length — 3.2 cm. Width — 3.5 cm. Color, adaxial surface — Green-white, nearest to RHS 157C. Color, abaxial surface — Yellow-green, nearest to a mixture of RHS 145B and 146D. Margin — Entire; coarsely undulate. Texture and luster of adaxial surface — Smooth, glabrous and glossy. Texture and luster of abaxial surface — Smooth, glabrous and moderately glossy to glossy. Color — Juvenile foliage, adaxial surface — Nearest to in between yellow-green and green; RHS 147A and NN137A. Juvenile foliage, abaxial surface — Green, nearest to RHS 137A. Mature foliage, adaxial surface — Green, nearest to in between RHS NN137A and 139A, yet considerably darker. Mature foliage, abaxial surface — Yellow-green, nearest to RHS 146A, and lightly suffused with green, RHS 137A. Venation — Pattern — Parallel. Color, adaxial surface — The main vein nearest green, nearest to in between RHS 137A and 143A.
