Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Dracaena steudneri Schweinf. ex Engl.

Variety denomination: The inventive cultivar of Dracaena disclosed herein has been given the variety denomination ‘JANET LINDO’.

BACKGROUND OF THE INVENTION

Parentage: ‘JANET LINDO’ is a spontaneous branch mutation of an unnamed Dracaena steudneri plant (not patented) which typified the species. The mutation was discovered at a commercial greenhouse in Lubbeek, Belgium in March of 2018. The mutation was initially noted for its dark green foliage with broad yellow 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 ‘JANET LINDO’ is accomplished by way of rooting stem cuttings. Propagation was first performed in March of 2018 at the inventor's commercial greenhouse in Lubbeek, the Netherlands. Through five subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘JANET LINDO’ 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 ‘JANET LINDO’. These characteristics in combination distinguish ‘JANET LINDO’ as a new and distinct Dracaena steudneri cultivar:

    • 1. Dracaena ‘JANET LINDO’ exhibits broadly lorate foliage that is borne on a short, unbranched stem; and
    • 2. Dracaena ‘JANET LINDO’ exhibits foliage with the central portion of the lamina colored green to greyed-green foliage and longitudinally striped with fine light-green stripes; and
    • 3. Dracaena ‘JANET LINDO’ exhibits foliage that is very broadly margined with a mixture of yellow-green and yellow.

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 ‘JANET LINDO’ grown in Lubbeek, Belgium. This plant, grown in a 17 cm nursery container, is approximately 1.5 years 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 ‘JANET LINDO’.

 BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements, made in July of 2022, describe averages from a sample set of six specimens of 1.5-year-old ‘JANET LINDO’ plants grown in 17 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. ‘JANET LINDO’ 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).
