Stenocereus griseus

Description: Stenocereus griseus is a treelike cactus (3-)6-9(-10) meters high, sometimes branching at the base, sometimes with a definite trunk.

Blooming season: Stenocereus griseus blooms in spring, the flowers open at night but last until midday. Also Stenocereus griseus may have a second blooming later in season.

Cultivation and propagation: Stenocereus griseus is easy to grow but not cold hardy.
Growth rate: It produces good amounts of growth each year if kept well fed and watered throughout the warmest months, particularly if it has been acclimatized to accept full sun. It will make clumps given the best conditions.

Soils: It likes very porous fertile cactus mix soil.

Watering: Water regularly in summer, but do not overwater (rot prone), keep dry in winter.
Hardiness: Reputedly sensitive to frost, but less so if kept on the dry side prior to, and during, cold.

Exposition: Outside full sun, inside needs bright light, and some direct sun. Tends to produce a dense white bloom in strong light, which encourages also flowering and spine production.
