Abstract
The new cultivar Thunderbolt is especially characterized by its broadleaf evergreen foliage which has pronounced irregular yellow centers that cover an area of the leaf around the midvein, with the leaves inside the plant being of the same variegated color as leaves on the stem tips, thereby giving the plant as a whole a distinctive and striking dark green appearance with jagged stripes and spots of yellow accenting the foliage. The plant is further characterized by its profuse display of yellow-green flowers in May.
