Culture
Best grown in dry to medium moisture, lightly textured, well-draining soil in full to part sun. Prefers drier conditions in winter. In climates with hot summers, some afternoon shade is preferred. When watering, avoid wetting the foliage, as this can lead to rot. Easily propagated by division of offsets. Hardy in Zones 5-10.
Noteworthy Characteristics
Rosularia platyphylla, commonly known as rosularia or Turkish stonecrop, is a rosette-forming succulent found growing either singly or in small groups on rocky terraces and slopes in the mountains of Kazakhstan, Kyrgystan, and northwestern China. The rosettes of pale green, finely hairy, spatulate (spoon-shaped) foliage can reach up to 4" in diameter, and may form small, dense groupings of 3-5 rosettes. Upright flowering stalks (up to 6" long) emerge in summer, bearing a panicle of small, white, tubular flowers. This is a slow-growing species that will eventually spread by offsets to fill an 8" area. Its form and habit resemble those of hens and chicks (genus Sempervivum).
The genus name Rosularia means "rosette-shaped" and refers to the growth form of this
The specific epithet platyphylla means "broad-leaved", in reference to the shape of the foliage.
Problems
No major pest or disease problems.
