plant named ‘DRA201901’

Abstract

A new and distinct Dracaena plant named ‘DRA201901’ which is characterized by an abundance of foliage born on an unbranched stem, glossy green foliage with broad yellow-green margins, foliage that is slightly to moderately spiraled and distally curled downward, 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 ‘DRA201901’.

BACKGROUND OF THE INVENTION

Parentage: ‘DRA201901’ is a spontaneous branch-plant mutation of a Dracaena fragrans ‘004027J’ (not patented) which was discovered at a commercial greenhouse in Honselersdijk, the Netherlands in the summer of 2010. The mutation was initially noted for its abundant foliage with narrow yellow leaf margins. 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 ‘DRA201901’ is accomplished by way of rooting stem cuttings. Propagation was first performed in the summer of 2010 at the inventor's commercial greenhouse in Honselersdijk, the Netherlands. Through eight subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘DRA201901’ 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 ‘DRA201901’. These characteristics in combination distinguish ‘DRA201901’ as a new and distinct Dracaena fragrans cultivar:

• • 1. Dracaena ‘DRA201901’ exhibits an abundance of foliage born on an unbranched stem; and
  • 2. Dracaena ‘DRA201901’ exhibits foliage that is slightly to moderately spiraled and distally curled downward; and
  • 3. Dracaena ‘DRA201901’ exhibits foliage with coarsely undulate margins; and
  • 4. Dracaena ‘DRA201901’ exhibits glossy dark green foliage with broad yellow-green margins.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘DRA201901’ grown in Honselersdijk, the Netherlands. This plant, grown in a 11 cm nursery container, is approximately 16 weeks old from a rooted young plant; and

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage of ‘DRA201901’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements, made in May of 2020, describe averages from a sample set of six specimens of 12 week-old ‘DRA201901’ plants grown in 15 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. ‘DRA201901’ 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).
