Almost certainly the lack of sunshine we had last year. Fingers crossed we get better weather this year and hopefully it will then produce plumes for you again. I had a huge clump until a couple of years ago but it outgrew its space and began to die, so I helped it on its way with a bit of glyphosate. The stump will take years to rot away though and is too tough to remove without a tree stump grinder.
A trowel in the hand is worth a thousand lost under a bush.
