Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct cultivar of begonia plant known by the cultivar name Leprechaun and particularly characterized as to uniqueness by the combined characteristics of leaf coloration and color pattern, with the leaves having clear brown areas surrounding the veins and bright green areas between the veins; leaves having spirals at the base and short petioles; short growth habit and relatively slow propagation time and growth rate; superior hardiness, and generally insignificant flowering from a commercial standpoint.
