Echinocereus rigidissimus subsp. rubispinus | Barbie Cactus
€21,20
🌿 Morphology: Globose to cylindrical cactus, usually solitary or forming small groups with age. Stem approximately 7–15 cm in diameter, with numerous low ribs and slightly marked tubercles. The areoles are densely covered by short, flattened, and very closely spaced radial spines, in red, pink, magenta, yellow, and white colors, forming bands that give the plant its characteristic multicolored appearance. The roots are fibrous. It is also known as the Rainbow Cactus.
🌍 Origin and habitat: Cactaceae family. Native to northern Mexico and the southwestern United States; subsp. rubispinus is primarily associated with Sonora and Chihuahua, in arid mountain environments, rocky slopes, and mineral soils, generally between approximately 1,200 and 2,000 m in altitude.
🌡️ Temperature: Approximately USDA 7b–10a. It can withstand temperatures close to −10 °C when completely dry and properly acclimatized. For cultivation in Spain, we recommend keeping it above −7 °C, especially in pots, protecting it from rain and persistent humidity during frosts.
☀️ Light: A species with very high light requirements. During active growth, we recommend an approximate DLI of 25–35 mol·m⁻²·day⁻¹ of PAR. Intense lighting is essential to maintain compact growth and enhance the spectacular coloration of the spines.
💧 Watering and dormancy: It mainly exhibits spring-summer growth, with a marked slowdown during winter. In spring and summer, water abundantly and allow the substrate to dry completely before the next watering. In autumn, progressively reduce water, and during winter, keep it completely dry, especially below 10 °C.
🌸 Flowering: Large and very showy flowers, from pink to magenta, with a lighter center, appearing near the top of the stem. Flowering usually occurs mainly between April and June, coinciding with the beginning of the growth period.
🧪 Nutrition: During spring and summer, fertilize with a nutrient solution with high assimilable calcium content, such as Desert CHOICE Cactaceae, at a moderate and regular dose. At the end of summer, progressively reduce fertilization and suspend it during winter dormancy. Avoid excess nitrogen to maintain compact form and spine quality.
