Raspberries grow in cooler climates in places such as the Pacific Northwest and Upper Michigan Peninsula. The development of adaptable raspberries allows gardeners in other climate zones to reap large raspberry harvests. However, adaptability only exists in a fenced garden, not out in the wild. The berry possesses the same type of bumps found on blackberries, but the red color makes raspberries easy to distinguish. Raspberries can also appear gold, blue, or purple. Small and round, raspberries project tiny hairs on the surface that also act as a distinguishing feature of the fruit. The plant propagates by using underground basil shoots, which allows the plant to spread rapidly.
