Pachycereus Overview

Pachycereus is a small genus from Mexico and Southern Arizona, containing just 6 species of tall shrub or tree-like cacti in the Pachycereeae (columnar cactus) tribe within the Cactaceae family. They have characteristic columnar ribs, are prolifically branched and have spiny fruits. In cultivation, members of this genus are usually only found as specimens in botanical garden deserts or arid glasshouses. Funnel- or bell-shaped flowers are produced only on mature specimens. One member of the genus, P. pringlei, is the tallest cactus species in the world – with one individual holding the record at 19.2 metres!
