Narrative
Probably the oldest erect blackberry clone in modern commercial cultivation, and the second ever to be named and introduced to the nursery trade - around 1850. Exceptionally sweet.

Lewis A Seacor named this cultivar named for William Lawton, discoverer

Luther Burbank stated that this clone is "fixed" implying that this cultivar is mostly homozygous and breeds true from seed. The cultivar is tetraploid (2n = 4 x = 28)
