Sempervivum Butterpat

The name translates as 'pieces of butter'. The thick-leaved foliage of the hybrid from Belgium shows a metallic, almost violet-blue sheen in spring. It actually looks like it's smeared with butter.
a great variety that shows very cool rosettes. However, the bright red ends of the leaves, which can really glow, are particularly noticeable!
