Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and unique variety of Norway maple tree, as herein described and shown, characterized by a vigorous, oval-rounded growth habit; strong, sturdy trunk; excellent insect and disease resistance; and unique leaf development; the new leaves are a rich ruby-red and display a unique wrinkled-crinkled appearance. The margins are crinkled and undulating, giving the entire tree a bright almost sparkling appearance; as the leaves mature, the ruby-red color changes to deep maroon and finally dark green; the entire color metamorphosis takes place over a 4 to 6 week period; the emerging and newly developing leaves make the tree appear as if it is in flower, gradually this strong focal point is softened as the leaves mature.
