Eriosyce choapensis

Eriosyce choapensis

Overview\nEriosyce choapensis is a highly prized and rare globose cactus species belonging to the family Cactaceae, endemic to the arid regions of Chile . It is well adapted to surviving in hyper arid habitats.\n\n Taxonomy\nNamed after the Choapa province in Chile, this species has historically been classified under Neoporteria or Pyrrhocactus . Modern botanical consensus places it firmly within the diverse genus Eriosyce.\n\n Distribution and Habitat\nIts natural range is confined to the Choapa Valley in the Coquimbo region of Chile. It grows on rocky slopes, barren scree, and mineral heavy soils with practically no organic matter .\n\n Appearance\nThe plant is single stemmed, globose to short cylindrical, with a dark green to greyish epidermis. It features pronounced ribs adorned with strong, central, and radial spines. It produces funnel shaped flowers ranging from yellow to reddish hues near the apex .\n\n Cultivation\nThis species demands exceptional drainage and maximum sunlight exposure. Watering must follow the "soak and dry" method, and the soil must remain completely dry throughout the cold winter rest.\n\n Common Mistakes\nOverwatering is the primary cause of failure, rapidly leading to root rot. Using standard potting soils instead of gritty mineral mixes, and keeping the plant in shaded conditions will cause etiolation.\n\n References\n Kew Plants of the World Online (POWO), Eriosyce Database.\n International Cactus Adventures, Taxonomic review of Chilean Cactaceae.
