Abstract
A distinct Dracaena plant named ‘0102RB’ characterized by its leaf coloration which is unlike any other known Dracaena Vand. Ex. L. fragrans (group Compacta) variety; leaf margin is approximately 1 mm to 10 mm in width and dark green (RHS 139 A), center stripe is approximately 2 to 10 mm in width and greyish green very fine stripes (between RHS 189 A and 190 D); two other stripes between center stripe and margin are approximately 1 to 5 mm in width and pure white; and the stripe between the pure white stripe and the center stripe is green (RHS 145 A), approximately 5 to 10 mm in width with very fine white lines.
Description
Dracaena Vand. Ex. L. fragrans (group Compacta)
0102RB
The present invention comprises a new and distinct cultivar of Dracaena plant botanically known as Dracaena Vand. Ex. L. fragrans (group Compacta) and hereinafter referred to by the cultivar name ‘0102RB’.
The new cultivar was selected by the inventor, Ruud A. M. Scheffers, in Honselersdijk, in 2000. The new cultivar was obtained as a natural mutation of Dracaena Vand. Ex. L. fragrans (group Compacta with cultivar name ‘Compacta Variegata’.
The new cultivar was first asexually propagated by the inventor in Honselersdijk, The Netherlands, in 1998. Subsequent asexual reproduction of the new cultivar by division has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.
The following traits have been repeatedly observed and in combination distinguish ‘0102RB’ as a new and distinct cultivar:
1. leaf coloration which is unlike any other known Dracaena Vand. Ex. L. fragrans (group Compacta) variety;
2. leaf margin is approximately 1 mm to 10 mm in width, and dark green (RHS 139 A);
3. Center stripe is approximately 2 to 10 mm in width, and greyish green very fine stripes (between RHS 189 A and 190 D);
4. two other stripes between center stripe and margin are approximately 1 to 5 mm in width of pure white; and
5. the stripe between the pure white stripe and the center stripe is green (RHS 145 A), approximately 5 to 10 mm in width with very fine white lines.
‘0102RB’ has not been observed under all possible environmental conditions. The phenotype on the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and daylength without any change in genotype. The following observations, measurements and values describe plants grown in Honselersdijk, The Netherlands under greenhouse conditions which closely approximate those generally used in horticultural practice.
In comparison with the well-known Dracaena cultivar Dracaena Vand. Ex. L. fragrans (group Compacta) ‘Compacta Variegata’ (unpatented), ‘0102RB’ has similar shaped and structured leaves but the coloration is entirely different.

The accompanying photographs illustrate a 16-weeks old plant of Dracaena ‘0102RB’, with colors being as true as possible with illustrations of this type. The first drawing shows a 16-weeks old plant of Dracaena ‘0102RB’. The second drawing shows a 16-weeks old plant of ‘0102RB’ propagated from a top together with a 16-week old plant of ‘Compacta Variegata’ propagated from a tip.
Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used. Colors are approximate as color depends on horticultural practices such as light level and fertilization rate, among others.
Parentage: Dracaena Vand. Ex. L. fragrans (group Compacta) ‘Compacta Variegata’.
Propagation: Primarily by vegetative division of the plant head or apical meristem.
General observations:
Growing conditions.—‘0102RB’ is grown in a greenhouse. The grower propagates ‘0102RB’ in a normal commercial greenhouse under temperatures of 20-21 degrees Celsius day and night.

Highest temperature resistance is at least 40 degrees Celsius, lowest is 5 degrees Celsius. Resistance, tolerance and susceptibility to stresses, pathogens and pests is very good. Compound fertilizer is added to the soil. There are no other cultural or environmental treatments.
