Has anyone wondered why there’s no mulberries in grocery stores?

I have. I’ve wondered why we can’t buy mulberries in grocery stores.

I had the chance once to pick and eat mulberries from a mulberry tree. They were delicious. They tasted sort of like blackberries, but sweeter. And come to find out, they’re super healthy. The Chinese say mulberries can cleanse blood. They boost the immune system, help with digestion, boost metabolism, reduce appearances of blemishes and age spots, among more. After eating mulberries for the first time, I wanted more. I’d buy mulberries at the grocery store every week if I could. But they aren’t in grocery stores! What a tragedy!  I want mulberries!
