Pachycereus pringlei (S.Watson) Britton & Rose

🌱 Morphology
Arborescent columnar cactus of extraordinary dimensions, capable of reaching 15–20 m in height and over 1 m in diameter in exceptional specimens. It develops a very thick trunk and numerous ascending branches, generally beginning to branch at a certain height. Young stems feature 10–16 obtuse ribs and densely arranged areoles; adult plants considerably reduce their spination and acquire a bluish-green epidermis. Young spines are robust, whitish to grayish, up to about 3 cm long.

🌍 Distribution, habitat, and family
Species endemic to the Sonoran Desert, distributed throughout much of the Baja California peninsula, numerous islands in the Gulf of California, and the coastal strip of Sonora, Mexico. It grows on both alluvial plains and rocky slopes, from areas near sea level to higher altitudes. It belongs to the Cactaceae family, subfamily Cactoideae.

❄️ Temperature · USDA Zone 9b
Tolerates minimum temperatures down to −4 ºC when dry and in well-acclimated specimens. It is a species sensitive to intense frost, especially in young specimens, so cold should always be combined with a completely dry substrate.

☀️ Lighting
Requires direct sun and very intense lighting to develop compact growth and a robust structure. During active growth, a PAR DLI of 20–30 mol·m⁻²·day⁻¹ is recommended as a reference.

💧 Growth cycle and watering
Winter dormancy. During the cold months, it is kept practically dry. In spring and summer, it can receive deep, spaced waterings, allowing the substrate to dry out completely between them. In cultivation, persistent excess moisture should be avoided, especially when temperatures drop.

🌸 Flowering
One must wait at least 20-25 years to observe its first bloom. The flowers are white to creamy-white, infundibuliform or bell-shaped, up to about 8 cm, and appear mainly during spring and early summer. They open at dusk and remain open during part of the morning, being visited by nectar-feeding bats, as well as birds and insects. The fruits are globose and covered with areoles with yellowish felt; upon ripening, they contain a juicy pulp and numerous large seeds.

🌿 Nutrition
During the period of active growth, a fertilizer with a high content of assimilable calcium and low nitrogen levels, such as Desert CHOICE® Cactaceae, is recommended, applied once a month when watering. Before flowering, it can be supplemented with Desert CHOICE® Flowering.
