Petrorhagia saxifraga


This Dianthus relative is a common ground cover in Europe, and its hardiness and drought tolerance make it an excellent choice for green roofs. Foliage is finely textured and bright green. Multiple tiny, pale pink flowers add delicate color throughout the summer and into early autumn. Currently underused on green roofs, this plant is a great textural contrast to sedum and is almost as tough.

Large orders may require custom growing. Please contact the office for lead times.
