Clint, there are some varieties that seldom bloom. We'll have to see if we can come up with a list for you. : )
Tabby started the list with Oddity. I've never had mine bloom either.
I also have a tectorum type that in all the years I've had it (at least 12 years), it has only had maybe 2 or 3 rosettes bloom. But this one doesn't get but about medium sized.
The great thing about it is that by the time a rosette blooms it has already produced many offspring to carry on in place of the blooming rosette.
