Houseleek thrives in sunny locations where it can tolerate high temperatures and drought. They prefer well-drained soil, preferably stony or sandy, but are not very demanding. They are an ideal choice for rockeries, dry walls or roofs. Thanks to their shallow roots, they can take hold in a small amount of substrate almost anywhere. Watering should be rather moderate, overwatering could cause root rot. Fertilizing is not necessary, as the sedges can get by with very little nutrients. In general, therefore, almost no care is needed and it will grow happily in almost any drier, bright location.
