Increased well for me, too, but took about three years in my garden to get to the point where it performed well enough that I could see what everyone was excited about. And even then, I was having a good year if I was getting 16-18 blooms on a scape, which less than the 30-something it is registered at. But, that's not that unusual when you buy plants created in the south and plant them in the north. Slightly more disappointing is I bought it because it's registered as an early bloomer, and it doesn't do that in my garden. More like a late blooming EM or an M for me.
It was definitely a nice plant for me. Just not what I was expecting.
