Micranthocereus albicephalus

A columnar cactus up to about 2.5 m tall that branches from the base. Mature stems grow a woolly, bristly cephalium where the white night flowers open. It comes from rocky, dry shrubland at about 800–1,350 m in southern Bahia, so give it hot, very bright summers with water and a dry, cooler winter.

Where it grows wild

Grows among rocks and in dry shrubland on the hills of southern Bahia, in the zone where caatinga meets campo rupestre. The plant stands in the open with little shade from the shrubs around it.

Records run from 775 to 1,360 m, median 950 m. These are upland sites, so nights are cooler than in the lowland caatinga.
