Kniphofia hardiness

I have Kniphofia northiae here for ten years.  Has increased and sent up two offsets.  Kniphofia hirsuta had lasted about three years and then dwindled. Most likely due to it's location rather than temperatures.  The K. northiae hasn't flowered every year but puts on a good dramatic leaf show.
