An interesting tropical cactus also called the 'Gray Ghost organ pipe' that occurs in many different areas of Mexico, this species is a columnar cacti with bluish-green coloration and a dusty-looking coating of white powder on new growth. It features white flowers that bloom both day and night to allow for pollination 24-hours a day, and produces ovoid, edible fruit about the size of a small apple.
The namesake 'Pitayo de Octubre' and 'Pitayo de Mayo' describe its habits of blooming and producing fruit in both Spring and Fall, namely in May and October. The color of the fruit ranges from yellow-orange to green and purple.
This is not a cold hardy cacti, but will take colder temperatures if the soil is dry. If grown in a container, it will also maintain a smaller size.
