Copiapoa tenuissima x atacamensis E4

Copiapoa tenuissima × atacamensis is a hybrid cactus that displays traits from both parent species. It typically forms small clumps of cylindrical to globular stems, each up to 10 cm tall and 5 cm in diameter. The epidermis is green to greyish-green, with numerous ribs lined with small, woolly areoles. Spines are yellow to brown, relatively short, and evenly distributed along the ribs. During the summer, it produces small, funnel-shaped yellow flowers near the stem apex. This hybrid is adapted to arid conditions, thriving in rocky, well-draining soils with minimal water requirements.
