Saguaro flowers. The white, waxy flowers appear in April through June, opening well after sunset and closing in midafternoon. They continue to produce nectar after sunrise. [25] Flowers are self-incompatible, thus requiring cross-pollination. [7] Large quantities of pollen are required for complete pollination because many ovules are present.

The phenomenon may occur in the stem, root, fruit, or flower head. Some plants are grown and prized aesthetically for their development of fasciation. [ 3 ] Any occurrence of fasciation has several possible causes, including hormonal , genetic , bacterial , fungal , viral and environmental causes.
Saguaro National Park is a national park of the United States in southeastern Arizona. The 92,000-acre (37,000 ha) park consists of two separate areas—the Tucson Mountain District (TMD), about 10 miles (16 km) west of Tucson , and the Rincon Mountain District (RMD), about 10 miles (16 km) east of the city.
Some species can grow to be over 15 m (50 ft) tall, like the saguaro (Carnegiea gigantea) [2] and Cephalocereus macrocephalus (syn. Neobuxbaumia macrocephala). [3] Their stems are ribbed and columnar, not divided into segments. Most have flowers that open at night. [1]
The cactus family, the Cactaceae, evolved 30–40 million years ago in the Americas, [3] originally completely separately from Africa, Europe, and Asia, although, probably within the last few million years, some species of Rhipsalis appear to have been carried to parts of Asia and Africa, [4] most likely by birds.
