T. peruvianus naturally tends to grow arching or prostrate with age; on rocky Peruvian cliff shelves it grows downward and outward, and short-spined forms were collected from the wild above Matucana.

Growing & propagation
T. peruvianus tolerates bright light but suffers in hot full sun, prefers cooler coastal conditions over excessive heat, and handles wet winters and mild freezes well in California. [Trout's Notes on the Cultivation & Propagation of Cacti]
Clone genealogy
KK242 entered Western horticulture via two main routes: seed (KK242) grown by Abbey Garden in California (studied by Pardanani et al. 1977), and living clones obtained from Knize and grown in the southern USA (studied by Ogunbodede et al. 2010). [WVC 2011 San Pedro talk; Pardanani et al. 1977, Lloydia 40(6):585-590; Ogunbodede et al. 2010, Journal of Ethnopharmacology 131(2):356-362]
A cultivar in German horticulture, originally collected in Peru by a German collector named Kaiserwerth, is sold under the name Trichocereus peruvianus. [Pachanoi or Pachanot? (Keeper Trout, Trout's Notes)]
