'Pilioseum' forms medium to large rosettes of grey-green leaves. This color may vary from season to season. These rosettes have a rounded, semi-loose form.
Sempervivum is comprised of one large rosette called the "hen" which sprouts many smaller rosettes around it called "chicks". As the plants age, the "hen" may die out and be replaced by the "chicks". Plants can be divided easily at any time by pulling up some of the "chicks" and replanting them elsewhere.
This plant is particularly effective when planted in the cracks and crevices of stone walls or walkways. It is also very attractive in containers.
