Q.Can i propagate a broken branch from my Pinky Winky Hydrangea?
It was a new 1 gallon plant last year that did flower. The snow has just left the area and it is still below freezing most nites. No leaves are developing yet. Is it possible to take stem cuttings from this branch?
Yes, now is an OK time to take cuttings. A stem that did not flower last year may be a good choice. Cut it 5-6 inches long. An article with further info on propagating hydrangeas follows: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/hydrangea-propagation.htm
