Abstract

A new and distinct Dracaena cultivar named ‘Dragongdor’ is disclosed, characterized by wide green leaves with yellow margins. The new variety is a Dracaena, typically produced as an ornamental plant.

Description

Latin name of the genus and species: Dracaena fragrans.
Variety denomination: ‘Dragongdor’.
BACKGROUND OF THE INVENTION
The new cultivar is the product of chance discovery. The new variety originated as a naturally occurring branch mutation of the variety of Dracaena fragrans ‘004027J’, U.S. Plant Pat. No. 21,830.
The new variety was discovered by the inventor, Ruud A. M. Scheffers, a citizen of the Netherlands, in July of 2009 in a commercial greenhouse belonging to the inventor in Honselersdijk, The Netherlands. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation of ‘Dragongdor’ assessing stability of the unique characteristics of this variety.
Asexual reproduction of the new cultivar ‘Dragongdor’ was first performed at the commercial greenhouse of the inventor in Honselersdijk, The Netherlands by vegetative cuttings in July of 2009. Access to all plants was restricted, as plants were kept in a locked greenhouse not open to the public. Through subsequent propagation by vegetative cuttings, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.
SUMMARY OF THE INVENTION
The cultivar ‘Dragongdor’ 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 ‘Dragongdor’. These characteristics in combination distinguish ‘Dragongdor’ as a new and distinct Dracaena cultivar:
    • 1. Wide green leaves with yellow margins.
PARENT COMPARISON
Plants of the new cultivar ‘Dragongdor’ are similar to the parent, Dracaena fragrans ‘004027J’ U.S. Plant Pat. No. 21,830 in most horticultural characteristics. The new variety, however, produces leaves with a different color of margin compared to those of the parent.
COMMERCIAL COMPARISON
‘Dragongdor’ is in plant habit, and other horticultural characteristics most similar to the parent variety. ‘Dragongdor’ can however be compared to the commercial variety Dracaena fragrans ‘Lauren’, U.S. Plant Pat. No. 21,549. Plants are of the same species and both with variegated foliage. However, plants of ‘Dragongdor’ have distinctively twisted foliage, thicker foliage and a variegation pattern with a dark green leaf and creamy yellow margin. Plants of ‘Lauren’ produce green foliage with green-white streaks.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘Dragongdor’ grown in a commercial greenhouse in Honselersdijk, The Netherlands. This plant is approximately 2 months old, shown planted in a 15 cm container. The photograph was 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.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘Dragongdor’ plants grown in a greenhouse in Honselersdijk, The Netherlands. A steady temperature of approximately 20° C. at night and 20° C. during the day was maintained. No artificial light, photoperiodic treatments were given to the plants. Measurements and numerical values represent averages of typical plant types.
