No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.
Abstract
A kalanchoe plant having the charcteristics of both a yellow color and a distinct lemon fragrance which is not known in other yellow kalanchoes, together with a tall growth habit of approximately 12 to 16 inches, the profusion of flowers on sturdy stems, with the further aspect of adaptability to year round flowering effected by photo period control, the flower color and form being maintained for relatively long periods of time even though growth takes place in a relative dark home environment.
