The original plant was given to me by a friend who bought it at a grocery store at Easter 5 years ago so I have no idea what kind of hydrangea it is. It has had multiple blooms (huge) each year until this year and never grows over two feet high. There are lots of healthy leaves this year but not even a sign of a bud. I have cut it back to ground level every fall since planting it and our winter here was not any worse than usual. Anyone have any ideas?
