In the many years I've had Oddity, it has never bloomed. Many times it has produced normal looking, flat-leafed rosettes that seem to grow in a normal fashion for about a year. Then the leaves turn into the tube form of oddity.

Oddity would make a great addition to a miniature garden, by using a single rosette as maybe a shrub? Let your imagination decide how you might use it in your miniature garden.

I find 'Oddity' to be quite temperamental when planted in the ground in our zone 4 climate. It tends to rot in the spring from too much moisture when the snow melts. I built a bit of a mound for it this summer with lots of grit incorporated into the soil. We'll see if that helps.
