Abstract

A grape vine generally similar to the Black Rose grape vine (unpatented), but distinguished therefrom by being of more vigorous growth and by bearing grapes which mature about 30 days later, which have superior shipping characteristics, and which ripen more evenly so that each grape of the new variety is more uniformly and darkly colored than grapes of the Black Rose variety.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

Having thus described and illustrated my new variety of grape vine, what is new and desired to be secured by Letters Patent is: 1. A new and distinct variety of grape vine, substantially as illustrated and described, characterized by its resemblance to the Black Rose grape vine (unpatented), which it most nearly resembles, in bearing fruit of large size having a dark, approximately black skin, the new variety being characterized as to novelty by having leaves of extremely large size and berries having a heavy bluish-gray bloom and by being distinguished from the Black Rose variety in that the new variety is of more vigorous growth and bears fruit which matures about 30 days later, has superior shipping qualities due to a tougher skin and heavier stem, and being further distinguished from the Black Rose variety by more even ripening of each bunch so that each berry of the new variety has a skin color which is substantially solidly and uniformly dark except for a small annulus about the stem.
