Noteworthy Characteristics

Orostachys aggregata is a succulent, sedum-like, low-growing perennial that forms basal rosettes to 4” tall and spreads over time to 12” or more. Oblong-to-oval, grayish-green leaves (to 1” long) are thick and fleshy. Leaves turn purplish in fall. Spikes of tiny white to pale yellow flowers in late summer bloom on upright stems. Spreads by forming plantlets at the tips of its stolons. Closely related to Sedum.

Genus name comes from the Greek oros meaning mountain and stachys meaning spike in reference to its mountain habitat and flowers in spikes.

Specific epithet means aggregated or clustered in a dense mass.


No serious insect or disease problems. Watch for aphids. Crown rot may occur in moist, poorly drained soils.


Best grown in rock gardens as an accent or small scale ground cover.
