I am currently in the middle of a little walk and I found a beautiful “carpet” of Sedum coeruleum, a stunning red Crassulacea. They actually thrive on calcareous rocks and tend to root in the rocky substrate (litophyte). They are excellent bioindicators, (since they can accumulate heavy metals) and are very useful when it comes to prevent soil erosion! What’s your favorite crussulacea? Do you know any other species that comes from the genus Sedum? Let me know!
