Growing plants on rooftops is an old concept that has evolved from simple sod roofing to lightweight "extensive green roofs". Researchers have evaluated the influence of substrate type and depth on establishment of five common green roof plants. A standout performer was saxifrage pink, which had an attractive appearance and persistent flowering habit, making it an excellent choice as a green roof plant.
