Stenocereus pruinosus - Gray Ghost Organ Pipe

Highlights

Gray Ghost Organ Pipe (Stenocereus pruinosus) (Buxbaum): Powdery blue-green columnar cactus from Mexico. In the wild, it can eventually grow to 20.0' with new branches sprouting from the base and trunk, but in cultivation it tends to stay under 6.0'. Young plants are deeply ribbed and have reddish brown spines, but with time the 5-8 ribs flatten and the spines turn white. When it blooms, it opens 2.0" to 3.5" white and magenta, funnel-shaped flowers in the night that stay slightly open during the day.

This cactus variety will not survive a hard frost, but if there is a risk of freezing temperatures it can be brought indoors to grow on a sunny window sill or under a grow light. Cactus need bright sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 70% to 80% mineral grit such as coarse sand, pumice, or perlite. Water deeply and wait for the soil to completely dry out before watering again.
