Sempervivum arachnoideum – Sempervivum arachnoideum – Sempervivum arachnoideum – Fatty plants – Sempervivum arachnoideum – Succulents

a group that includes dozens of evergreen succulent plants from Europe, America and Asia. They appear as dense rosettes of fleshy leaves, mostly rounded, sometimes elongated, of various colors, from light green to blue-green, up to black-purple. Some varieties are covered by a soft down, which is often present on the margins of the leaves of many varieties. The rosettes tend to form wide cushions, producing new plants at the end of long stolons, which, growing up, tend to root singly.

Plants at least three years old produce a raceme of small star-shaped flowers, at the apex of a long fleshy stem. After flowering many plants produce fertile seeds, and then die.
