Moonstones

Moonstones (Pachyphytum oviferum) is one of the most elegant succulents in cultivation, admired for its plump, rounded leaves that appear dusted with a soft pastel bloom. Native to the steep rocky cliffs of San Luis Potosí in central Mexico, it grows in crevices where excellent drainage and seasonal rainfall allow it to survive long dry periods. The thick leaves act as water reservoirs, while their powdery wax coating, known as farina, reflects intense sunlight and helps reduce moisture loss. The species was first collected around 1909 by the German botanist Joseph Albert Purpus, whose explorations introduced many remarkable Mexican succulents to horticulture. The species name oviferum means “egg-bearing,” a reference to the smooth, rounded leaves that resemble small polished eggs. During spring and early summer, mature plants produce graceful flower stalks carrying small, bell-shaped flowers with creamy white petals and vivid red interiors, adding an unexpected splash of colour to the plant’s soft blue-grey foliage.
