These were marked as goji at a plant swap, but they're not gojis. They didn't fruit or bloom last year but they did put on a few feet of growth. Fleshy, 5-sided stem.

What is your location please?

I'm in Oregon, zone 8!

That's definitely a gojiberry. They can take a few years to bloom and set fruit.

Yikes! I'm so confused now! I have another plant that I bought that looks fairly different-it has a woodier stem that us round rather than five sided, a floppy rather than op right growth habit, slightly different leaves and no purple spot at the node. It flowers purple and makes orange berries that look and taste like what I see in the store as goji. Is the word used for two different plants/fruits?

There's lots of photos of the leaves, flowers and fruits to compare with what you have.
