About the genus · Pachycereus
Pachycereus is a genus of large cacti native to Central America and Mexico. They form large shrubs or small trees up to 15 m (49 ft) tall, with stout stems up to 1 m in diameter. Pachycereus comes from the ancient Greek παχύς meaning "thick" and the Latin cereus meaning "torch".

Cultivation
Grouped as a cactus or succulent by the genus Pachycereus, which is reliably one kind of plant (archetype table). The table holds no figure for this group, which spans too much for one minimum, and no habitat climate is derived yet; no cold floor is given, and no prose comes from the table.
