It may be an invasive species but at least they're delicious!
Emily@deliverance ooh! How do you tell the difference between them and raspberries?
@Emilyy Easy, wineberries grow in my yard and raspberries don't 😁
I'm far from an expert but I think they're smaller than raspberries, and the plants are covered in little hairs that look like thorns (but don't hurt!).
@deliverance I was so intrigued by the wineberry content that it didn't even occur to me immediately to research! The online botany sites point to the little hairs too - so that's also what we have! Thanks for the info!
