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
This is a variety of Syringa pekinensis and has been reproduced asexually from a tree found growing at Milwaukee, Wisconsin with the characteristics of an upright growth habit of 12 feet wide and 18 feet tall without the benefit of cultural pruning and trimming. Propagated by me asexually it produced straight-growing progeny with a strong central leader; a tree crown producing an abundance of fine textured deep green leaves and large cream colored flower trusses annually. The bark is a lustrous reddish-brown with many very horizontal lenticels. Progeny produced show rapid and sustained growth.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinctive variety of Syringa pekinensis named `Summer Charm` as shown and described herein that differs from all other varieties by the unique combination of: (1) large panicles of creamy-white flowers produced annually and not intermittently; (2) narrow, upright tree habit; (3) outstandingly thick glossy, fine-textured foliage resulting from the production of an abundance of leaves borne; (4) attractive lustrous dark-brown bark with an abundance of light-colored and persistant lenticels.
