Very cool slice, Stefan. I was proud of myself when I could guess the tribe (Aeonieae) based on just a couple of flowers.
I had an Aichryson back in the day, and propagated it, but then the mother plant went to seed and that was the end of that. They are indeed lovely miniatures. The flowers are outsized compared to the leaves. Word to the wise: these are not long lived plants, more like something to appreciate while it lasts.
