The primary difference is the growth habit of their canes. Erect blackberry types have stiff, arching canes that are somewhat self-supporting. Erect blackberries are more cold-hardy than trailing types. However, you can grow trailing types in colder areas if you leave the canes on the ground and mulch them in winter. All of these are species and hybrids of the genus Rubus, and all have similar fruiting habits.
All blackberry plants are perennial, with roots living for many years.
The floricanes die after they have fruited. New canes are produced each year from roots or the base of old canes. The floricanes need to be removed each year after harvest, but the new primocanes, which will fruit the following year, need to be thinned and trained. Selecting a Site Blackberries produce best in full sun, but they can tolerate partial shade. However, plants do not grow or produce well in heavy shade.
