Re-posting from Instagram (my post).
I was telling Heather of @rollingblooms about the seemingly quite odd growth habit of my Marionberry Milkshake stock from last year. There were no symptoms of either of the galls, etc., but when I dug the clumps (3), I almost didn't save them. I just pulled this one out of its little 3.5" pot to show y'all. What I had found was little stems that grew underneath or to the side of a tuber in the clump, away from the clump, and a node had formed for the eye. I've enlarged this photo probably 200 percent (or more) to show a closer look. This one was found recently in a small segment of one of the small sections of a clump that I couldn't decide how to divide, so I'd left it. This week I noticed a hint of green peaking out from in-between 2 of the tubers, pulled it & discovered it was another scenario of let's put out a stem ('twig') and put out a node too. You can see where the older 'twig' is putting out more underground "stem", and from that point, the roots had started to develop. I have a few that are even smaller than this that look like capital T's, with a node (eye) in the center where the two parts of the T connect, aka stem growing width-wise, with a stem that grows downward, with the node/eye at the top center of the "T" -- hoping that makes sense.
Have you experienced this? Seen this in other cultivars? Weird, no?!
