Hat tip to brena for contributing the (mostly unmodified) original pattern - this is a variation to create a branching vine. The last row in this map shows both branches of the vines just starting to make a new leaf stem, and from there it leads back into the original vine pattern, just with two branches now. Note it's not exactly equal to two horizontal repeats of the original pattern, because I just liked it with fewer stitches in between the two branches.
Shown with a cast-on count of 26 stitches.
