Notes
Aligned with the classic Southern California Mediterranean climate, this species wakes up and begins active growth with the arrival of cool autumn temperatures and seasonal winter rains. In a mild coastal climate like Zone 10b, it performs exceptionally well outdoors when staged beneath the bright, protective diffusion of a polycarbonate and wood shade house, which shields its delicate farina and compact leaves from harsh afternoon burning. It demands an uncompromisingly fast-draining, highly inorganic mineral substrate composed primarily of volcanic pumice, coarse granite, and decomposed granite with minimal organic matter. Water deeply only when the soil has dried completely during the cool active growing season, and keep it completely dry and well-ventilated during the dormant heat of summer to prevent crown rot.
Origin
Dudleya cymosa subsp. pumila (Glendora Mountain Dudleya)
Place of origin: United States. This rare, compact native succulent is endemic to the rugged, steep chaparral-covered slopes and rocky schist outcrops of the San Gabriel Mountains in Los Angeles County, with a classic distribution concentrated around Glendora Mountain Road. Growing at mid-elevations, it wedges itself tightly into narrow vertical rock crevices and shaded road cuts, where it endures baking summer heat, seasonal wildfire cycles, and dry foothill conditions. The plant forms a tight, miniature rosette of short, lance-shaped, grey-green to pale glaucous leaves that are often lightly dusted with a delicate powdery farina. In late spring, it pushes up slender, reddish floral stems bearing bright, cheerful yellow, bell-shaped flowers that contrast sharply against the foliage.
