| Abstract: |
A new and distinct Polygonatum plant characterized by foliage with a broad white variegated margin, red stems, and excellent vigor. |
| Claim: |
I claim:
1. A new and distinct Polygonatum plant as herein illustrated and described. |
| Description: |
Botanical denomination: Polygonatum odoratumvar. pluriflorum.
Variety designation: `Double Stuff`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Polygonatum and given the cultivar name of `Double Stuff` Polygonatum is in the family Convallariaceae. The new cultivar originated as a naturally occurring branch mutation of Polygonatumodoratum var. pluriflorum `Variegatum` (an unpatented plant) in a garden in Pennsylvania. This mutant has proved stable since it was discovered in June of 1997.
SUMMARY OF THE INVENTION
This new Polygonatum is distinguished by: 1. Foliage with a broad white variegated margin. 2. Red stems. 3. Excellent vigor.
This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by tissue culture using standard micropropagationtechniques with terminal shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding asexual propagations. The present invention has not beenevaluated under all possible environmental conditions. The phenotype may change with variations in environment without a change in the genotype of the plant.
