Pilosocereus pachycladus

A tall, blue-stemmed columnar cactus of the caatinga and rocky campos of eastern Brazil, recorded from near sea level to about 1,400 m. It wants very strong sun, real warmth all year and a dry spell in the southern winter and spring. Cold, wet roots are what kill it in cultivation.

Where it grows wild

Records run from 0 to 1,400 m, with a median near 500 m. Most sites are in the hot interior lowlands and low plateaus of the northeast.
