It is Oct. 17 and all the stems from one of my huge bleeding heart plants are laying on the ground .. dead, I thought. Now there are large clumps of what I believe are new plants growing along all these dead / rotting stems ...about 3 to five clusters spaced evenly along the length of each stem. I have never seen this happen before and wonder what I should do? It could decide to turn really cold any day now! I live in New Hampshire.
