The Arizona Queen of the Night has thin stems and large underground tuber that supposedly can reach 100 pounds.
Blooming Habits:
The strongly scented white flowers of this cactus are beautiful. They open at night in June, lasting only one night. They are often over 4 inches in diameter (10 cm). They are followed by a 3 inches long (8 cm) red-orange ovoid fruit, with black seeds.
Propagation:
Germinate the seeds between 70 and 85°F (21-30°C). They can be sown at any time of the year. The seedlings rot easily, keep in dry air and strong light. Cuttings are also very easy.
