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. 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.
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.

Famous quotes containing the word cultivation:
“Those who are esteemed umpires of taste, are often persons who have acquired some knowledge of admired pictures or sculptures, and have an inclination for whatever is elegant; but if you inquire whether they are beautiful souls, and whether their own acts are like fair pictures, you learn that they are selfish and sensual. Their cultivation is local, as if you should rub a log of dry wood in one spot to produce fire, all the rest remaining cold.”
—Ralph Waldo Emerson (1803–1882)
