We’re finally seeing almost the same number of ripe wild blackberries as red ones, which is a state of affairs that lasts approximately 30 seconds when you do the counting by mouth. But, do we know what we were eating when we pop one of these beauties into our mouths? Apparently not.
The literature reveals that blackberries are a fruit, of course – but, blackberries and raspberries are not berries, technically speaking. This is one of those areas where scientific definitions tend to contradict common assumptions. (One of the more readable articles on this is by Greta Lorge in Stanford Magazine’s July-August 2013 edition.)
Basically, a fruit is any seed-containing product of a flowering plant. A berry, technically, is a seeded fruit produced by one flower that has one ovary. But, blackberries and raspberries are produced from a flower that has multiple ovaries. Therefore, they’re classified by botanists as “aggregate fruits,” not berries. These definitions produce some surprises, including the fact that tomatoes, avocados, and bananas are “berries,” while blackberries are not, scientifically speaking. (Brooklin, Maine)
