The specific name setispina is a combination of the Latin words "setis" meaning "bristle" or "hair," and "spina," meaning "thorn" or "spine." This nomenclature highlights the prominent and distinctive spines that characterize this species, accurately reflecting its physical attributes.

Care Instructions
To successfully cultivate Cochemiea setispina, adhere to the following care tips:

• Light: Prefers bright, direct sunlight for optimal growth and flowering. A south-facing window or outdoor space with full sun exposure is ideal.

• Soil: Use a well-draining cactus mix or prepare a custom mix with sand, perlite, and potting soil to ensure adequate drainage and prevent root rot.
• Temperature: Thrives in warm conditions, ideally between 70°F to 85°F (21°C to 29°C). Protect the plant from frost and extreme cold temperatures.
• Fertilization: During the growing season, apply a diluted cactus fertilizer every 4-6 weeks to encourage healthy growth and vibrant blooms.
