I have been searching Google and Goole Images for a while, and cannot figure out what this is:
I just saw it yesterday. It’s growing on the stem of one of the grapes planted on our chain link fence. Here’s another shot:
It is very similar to the seed pods that grow on bur cucumbers (a related vine). I haven’t seen seed pods like this on grapes before, so I’m thinking it’s some kind of gall (growth), maybe caused by an injury. (And it definitely is growing on the grape vine, not a weed mixed in!)
I don’t know what kind of grape this is, unfortunately. We put in more than 100 vines from Great River Vineyard, and alternated varieties to keep the look visually similar on the green fence (eventually). We also had a few varieties from Bachman’s that we put in a few years earlier, and some that were transplanted from The Vineyard, a restaurant in Anoka that closed.
This is on an older vine, and I am going to guess it’s a Concord grape (which are the ones from Bachman’s). The grapes aren’t ripe yet, but here’s what they look like:
I’m hoping someone can shed some light on what this is! I’m tempted to cut it open, but I also want to see what happens to it as the weeks go by.
