Nightblooming cereus

Hylocereus undatus

Nightblooming Cereus is the common name referring to a large number of flowering cereus cacti that bloom at night. Because of the short life of the flowers, the nightblooming cereus has a romanticized reputation and has given rise to erroneous beliefs, such as that the plants bloom only once a year, or only on nights when the moon is full^{[citation needed]} The nightblooming cereus is also referred to as Princess of the Night, Honolulu Queen (for Hylocereus undatus, commonly grown in Hawaii), Queen of the Night, or Reina de la Noche.

Varieties

Most nightblooming cereus refer to flowering cacti of the cereus genus. While many cacti referred to as nightblooming cereus belong to the Tribe Cereaae, other night-blooming cacti in the Subfamily Cactoideae may also be called nightblooming cereus. Cacti called cereus include these genera and/or species:

• Cereus
• Echinopsis (usually Echinopsis pachanoi, San Pedro cactus)
• Epiphyllum (usually Epiphyllum oxypetalum, Gooseneck cactus; grown as an indoor houseplant throughout the world, and the most popular cultivated night blooming cereus)
• Eriocereus
• Harrisia
• Hylocereus (of which Hylocereus undatus is the most frequently cultivated outdoors, and is the main source of the commercial fruit crop, "Dragonfruit")
• Monvillea
• Nyctocereus (usually Nyctocereus serpentinus)
• Peniocereus (Peniocereus greggii, the best known, is strictly a desert plant which grows from an underground tuber and is infrequently cultivated)
• Selenicereus (usually Selenicereus grandiflorus)
• Trichocereus

Description

Regardless of genus or species, night blooming cereus flowers are almost always white, often large, and frequently fragrant.^{[citation needed]} Most of the flowers open after nightfall, and by dawn, most are in the process of wilting. The plants that bear such flowers can be tall, columnar, and sometimes extremely large and tree-like, but more frequently are thin-stemmed climbers. While some night blooming cereus are grown indoors in homes or greenhouses in colder climates, most of these plants are too large or ungainly for this treatment, and are only found outdoors in tropical areas.

Cultivation and uses

Some night blooming cereus plants produce fruits which are large enough for people to consume. These include some of the members of the genus Cereus, but most commonly the fruit of the Hylocereus. The Hylocereus fruit have the advantage of lacking exterior spines, in contrast to the fruit of cacti such as the Selenicereus fruit, being brightly colored, and having a pleasant taste. Since the late 1990s, Hylocereus fruit have been commercially grown and sold in tropical locations like Australia, the Philippines, Vietnam, Taiwan, and Hawaii.^{[citation needed]}

Around 2000, the name "Dragonfruit" was created for promotional purposes in English-speaking countries, undoubtedly influenced by the very successful renaming of "hairy gooseberries" as "Kiwifruit" earlier in the 20th century. The unusual exterior of a Hylocereus fruit, with its protruding growths, inspired the reference to dragons. Hylocereus fruits are also called pitaya. Increasing commercial cultivation, and the hybridizing of new varieties, is occurring for this fairly new crop. However, dragonfruit are usually somewhat expensive during their season (summer) and are still a specialty for most consumers.

• In the 18th century, Dr. Robert John Thornton commissioned the creation of lavishly illustrated portfolio of flora called "Temple of Flora". Plate #14 is of a "Night Blowing Cereus". (Missouri Botanical Garden Library ^[1])
• John Wesley, "John Wesley's Journal", Mon. 24 July 1780, describes the blooming and fading of the "Nightly Cereus" which had a 125mm dia. white centre, and 225mm dia. "yellow ray" petals.
• In Hawaii, nightblooming cereus crown the lava rocks ^[2] that border Punahou School.^[3] They are so associated with the school that their Hawaiian name is panini o kapunahou.^[4] and are regularly seen in many of the school's graphics, including that of the class of '74.^[5]
• The nightblooming cereus was featured in Barbara Kingsolver's book The Bean Trees. Taylor, Turtle, Lou Ann and Dwayne Ray witness the blooming of the cereus flower at their neighbour's house (Edna Poppy and Virgie Mae Parsons) towards the end of the novel (chapter 13).
• The nightblooming cereus was also featured in Jacqueline Carey's Kushiel's Legacy book series as the name of one of the Thirteen Houses of the Court of Night-Blooming Flowers.
