Disclaimer: I’ve never seen this before, but given my limited experience with sweet potatoes it doesn’t mean it is abnormal.
I believe that sweet potato vines are second only to gourd vines in their quest for geographical coverage and control. They seem pretty good at it too, sprawling in every direction and putting down an extra moisture seeking root every foot or two along each spur.
However, one of my vines seems to have mutated into a Siamese quintuplet or something, from a two lane country road into a multi-lane urban super highway.
This reminds me of the 40 pin serial hard drive connectors inside my older PCS. Go figure.
The type is “Beauregard” and one test harvest reveals that it is good for a substantial yield; one 4′x1′ hill was good for about 15 lbs of tubers.
The same, from a little further back:
That’s all, I just wanted to share this “head-scratcher”.
