Thanks for posting this, I never knew that a broken branch could start to root like this...great pics!
On the bright side, you have more chances for blooms this year: 1 from the mother plant and from the branches that broke off last year. And if you decide to cut the top from the Momma plant, not sure if the tip or the lower branch will recover fast enough to give you a bloom this year but you will have more plants and new branches from the Momma plant. Maybe wait for the bloom if you want blooms this year.
