Abundantly flowering houseleeks
On the Sonnenberg, north of Naturns.
Most houseleeks (genus Sempervivum) produce flowers varying from pale pink to deep red. When I searched for houseleeks with yellow ones, I found two candidates: S. globiferum and S. wulfenii. However, I couldn't determine which one these are. Pictures I found of the two showed green stems, not red ones, and the yellow was not nearly as intense. That makes me think this could be a cross between several species.
