The present invention relates to a new and distinct cultivar of
Polygonatum biflorum
and will be referred to hereafter by its cultivar name, ‘Kelli's Gold’. ‘Kelli's Gold’ represents a new Solomon's seal, an herbaceous perennial grown for landscape use.

Polygonatum biflorum
in 1989. ‘Kelli's Gold’ was selected from within a population of seedlings that were grown out from the seed collected from the unnamed plants of
Polygonatum biflorum
in Brookings, S.D. in the summer of 1990.
The new Solomon Seal was selected for its golden yellow foliage coloration. This characteristics makes this new cultivar unique and unlike any other known cultivars of
Polygonatum biflorum
known to the inventor.
