If you're talking about pruning after flowering is done and the plant is starting to die back, you would want to prune at ground level. I think. There's really not very much information on this plant, but based on the plant's appearance, that's what I would do if I had one. You might cut one of the stems in the middle, just to make sure it doesn't grow from such a cut. Did you know that if you don't cut off the flower and allow the inflorescence to bend over when the flowering is done, it will start a new clump of plants from where the inflorescence touches the ground?
