Coleocephalocereus
Coleocephalocereus is a genus of columnar cacti native to Brazil, primarily found in rocky, well-draining soils of arid and semi-arid regions. These slow-growing species are characterized by their slender, upright stems covered in dense spines, which provide protection from intense sunlight. A distinctive feature of this genus is the cephalium, a woolly and bristled structure that develops as the plant matures, serving as the flowering zone. The nocturnal flowers are typically white or pale pink, adapted for pollination by night-flying insects. Over time, these cacti may produce small, fleshy fruits that attract wildlife. Their unique morphology and resilience make them highly sought after by collectors and xerophytic garden enthusiasts.
