Even cultivars within the same type differ in fruit quality, flavor, appearance, tolerance to pests, cold hardiness and plant longevity.
Various types of raspberry differ in fruiting season and cultural requirements. It is important to choose a cultivar adapted to your region. Since it is such a prolific producer, you can often stop and enjoy the fruit while hiking (Figure 7). The native black raspberry (Rubus leucodermis), in contrast, is easy to identify by its purple stems.Deer and other animals typically eat these red raspberries before humans. The native red raspberry (Rubus strigosus) is more difficult to find, but is native to broad areas of Oregon, including at higher elevations.Plants produce large, white flowers (Figure 6A) and delicious fruit (Figure 6B) that has a low pulp-to-seed ratio, making it seem a bit seedy or dry. Thimbleberries prefer forest understories or mottled shade at various elevations. The thimbleberry (Rubus parviflorus) is native to broad areas of Oregon.You can find salmonberry in wetter, riparian areas in their broad native habitat (Figure 5). Birds usually eat the fruit before they are fully ripe. Plants produce beautiful dark pink flowers (Figure 4A) and berries that change from yellow to orange (Figure 4B) and then to dark maroon red when fully ripe. The salmonberry (Rubus spectabilis) has bright, dark brown, spiny canes that grow tall and arch over.You can find several raspberry species in the wild in Oregon, all of which fruit on the floricanes: Everbearing raspberry plants can be pruned to produce one crop (primocane only) or two crops (early summer on floricanes and late summer and autumn on new primocanes). Then the remaining cane base will overwinter and will fruit as a floricane in its second year, but will have a much lower yield than the summer-bearing types. The portion of the primocane that fruited dies back in late autumn or winter. Primocane-fruiting (fall-fruiting, or everbearing) raspberries have a similar cane development and life cycle, except the tips of the primocanes flower and fruit in the late summer or fall of their first year (Figure 3).After the planting year, raspberry plants will have both types - primocanes and floricanes - at the same time (Figure 2). They overwinter and then produce flowers and fruit in their second year, at which point the canes are called floricanes. These primocanes grow throughout their first year and then go dormant in the fall. Primocanes grow from buds on the crown and the roots (Figure 2). Floricane-fruiting, or summer-bearing, raspberries produce vegetative canes, called primocanes, in the spring.
