These are Goji berries. Know as brain food. I pick them starting mid summer all the way I to the early Fall. I freeze most of them and use them in smoothies throughout the year.

I’ve got 6 plants I started from seed in may. They are 6 ft tall in 1/2 gallon pots. I’m going to plant out this fall. Any suggestions about a good spot? Do they take over?
They don’t take over like I think you might be thinking. They do spread out from the top (they go up and hang out). They get 6 feet tall and they are about 6 feet wide as they spread out. We have 2 plants and that is plenty for 2 people to have a fresh handful everyday during the season and then for a handful of frozen ones in our smoothie everyday of the year.
