Do you know of any of these that are sterile and don't bloom? It would be nice to have some that get large and stay that way without blooming. I hate to see the large ones die.

Well, I've never seen a bloom on Oddity and I've had for decades. Mine don't get huge, but they don't get much water. They do sometimes revert to the common hen and chick which may bloom, or not. I've never paid attention to the ones that reverted once I tossed them among the other common ones.

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.
