ABSTRACT:
BACKGROUND OF THE INVENTION
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 ‘Kanzi’.
The new cultivar was selected by the inventor, Ruud A. M. Scheffers, in Honselersdijk, The Netherlands, in September of 1994. The new cultivar was obtained as a mutation of
Dracaena Vand. Ex. L. fragrans
(group Compacta) ‘Compacta Variegata’ (unpatented). This new variety was a natural mutation, discovered as a sport in a cultivated area.
The new cultivar was first asexually propagated by the inventor in Honselersdijk, The Netherlands, in November of 1994. 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.
BRIEF DESCRIPTION OF THE INVENTION
The following traits have been repeatedly observed and in combination distinguish ‘Kanzi’ as a new and distinct cultivar:
1. Longer leaves which are elliptic in shape with a distinctive point;
2. Elongated and less compact plant growth; and
3. Dark-green margin (RHS 135A) which is approximately 0.5 cm wide at center of leaf; center area which is dark-green (RHS 139A) to grey-green(RHS 191B) and 1.5-2.5 cm wide in center of leaf; between margin and center is a white (RHS 155C) strip which is approximately 0.3 cm wide at center of the leaf.
‘Kanzi’ is grown in a commercial greenhouse in temperatures of 20-21 degrees Celsius day and night. As with most Dracaena varieties, ‘Kanzi’ does not withstand direct sunlight so sun shields are used against bright sunlight. No artificial lighting or photoperiodic treatment is conducted. Highest temperature resistance is at least 40° Celsius and lowest is 5° Celsius. Compound fertilizer is added to the soil.
‘Kanzi’ has not been observed under all possible environmental conditions. The phenotype of 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 The Netherlands under greenhouse conditions which closely approximate those generally used in horticultural practice.
In comparison with the well-known Dracaena cultivar ‘Compacta Variegata’, ‘Kanzi’ has 5-10% longer leaves which are darker green, grey/yellow-green in color. The center color of the leaves of ‘Compacta Variegata’ is grey, whereas the center color of the leaves of ‘Kanzi’ is grey-yellow. The leaves of ‘Kanzi’ grow more upright than those of ‘Compacta Variegata’. ‘Kanzi’ grows more elongated than ‘Compacta Variegata’.
