Pot Size: 6"
Accepted Scientific Name: Echinocactus grusonii ‘Albaspinus’
Origin and Habitat:
Echinocactus grusonii is native to central Mexico, where it grows on rocky volcanic slopes and arid hillsides with excellent drainage and intense sunlight. The cultivar ‘Albaspinus’ is a highly desirable selection distinguished by its brilliant white spines rather than the typical golden-yellow spines of the species. In habitat, Golden Barrel Cactus experiences prolonged drought, mineral-rich soils, and seasonal rainfall, conditions that have shaped its exceptional durability and drought tolerance. Today, ‘Albaspinus’ is prized by collectors for its striking contrast between snowy white spines and its bright green body.
Description:
Echinocactus grusonii ‘Albaspinus’ forms a nearly perfect globe when young, gradually becoming barrel-shaped with age. Mature specimens may reach 24–48 inches tall and wide over many years. Deep vertical ribs are lined with dense clusters of bright white spines that create a dramatic architectural appearance. The pristine white spination reflects sunlight and highlights the plant's symmetrical form. Mature plants produce yellow flowers near the crown during summer, followed by woolly seed-bearing fruits. This exceptional cultivar serves as a focal point in containers, rock gardens, xeriscapes, and collector cactus displays.
