Petrorhagia saxifraga is often grown as a rock-garden or border plant, with several cultivars available in North America. Some North American records of P. saxifraga are from plants that either escaped from or persisted after cultivation. Most collections made since 1960 are from western Michigan, where P. saxifraga is known from naturalized populations in ten counties.
