There are many fruits and vegetables that look similar to one another, and this can lead to suspicions that the foods are actually related to one another. While it is not always the case, there certainly are many fruits that are closely related to other fruits which look similar.
So what about raspberries and blackberries? Are raspberries and blackberries related?
Yes, they are related in certain ways!
Both raspberries and blackberries are sometimes referred to as brambles or cane berries, and are actually not single fruits but rather aggregate fruits comprised of upwards of 100 smaller drupelets.
Another interesting fact is that neither blackberries nor raspberries are technically berries! As mentioned above, they are both actually aggregate fruits.
