Branches? Ours just had a stem off of which the leaves grew. They didn't develop a flower either, but I suspect it's some commercial variant, we just planted regular storebought supermarket chokes.
Cleaning up the garlic bed today so took some pics so you can see the branching.Yep, the main stem on the larger plants are about an inch or so in diameter and had multiple branches growing out of it, some of the branch tips sprouted flowers at well as tip top of the the main stem. I'll try to get a pic tomorrow of the remnants of the plants, we've had a couple of hard frosts here tho so they are about shot.
Here is one of the larger plants broken in half (at the rec circle) where I harvested the top for the chooks to chew on.
Main stem is just over 1"(2.5cm) at the base, next to it are my side cutters 7"(18cm) long and the largest rhizome I found.
Here's a milk crate with the other rhizomes I gathered....with same side cutters for scale
