Sempervivum Supersemp® 'Onyx' is a dramatic cold-hardy succulent with rich, burgundy-black rosettes that deepen in color with sun and seasonal shifts. A standout variety from the Supersemp® series, it brings bold texture and color to containers, rock gardens, green roofs, and more.
This evergreen perennial forms dense mats and multiplies by producing offsets (“chicks”) around the main plant (“hen”), creating a striking living carpet effect. Its unique coloring makes it a showstopper even in winter.
