Well now you do! There are also a number of items called apricorns you might find on your travels. Berries are better left fed to your Pokemon as they have some rather adverse affects on humans, and can range from healing to simply tasting good I've found. I only have a few on me, but typically if you find one berry plant, there's a good chance that plants nearby will also have a few ripe.

[[The examples she gives him are Oran, Persim and Cheri.]] I can't show you apricorns, but those are sort of...roundish items found on bushes similar to berries. I want to call them nuts? But I have no idea what they are. None of my Pokemon seem fond of eating them or even trying. But if you take these to a man in Azalea named Kurt, he's able to fashion them into different sorts of Pokeballs.
