Title: Night-flowering plant that blooms every five years
Answered by: Nan Hampton
QUESTION:
What plant flowers every five years at night?
ANSWER:
OK, Mr. Smarty Plants gives up—what plant flowers at night but only every five years? We know of several night-blooming native flowers, for example: Acanthocereus tetragonus (barbed-wire cactus) is found in Texas and Florida and blooms mid-summer to fall.
Peniocereus greggii (nightblooming cereus) is found in Texas, New Mexico and Arizona and flowering spring through summer.
Ipomoea alba (moonflower) is found in Kansas, Texas, Louisiana, and Florida.
Oenothera macrocarpa ssp. macrocarpa (Missouri primrose) (syn. Oenothera missouriensis) occurs in the central U. S.
Mirabilis multiflora (Colorado four o'clock) occurs in the southwest U. S.
But, so far as Mr. SP knows, each of these bloom every year, given normal environmental conditions.
There are any number of native biennial plants (for instance, the thistles in the Genus Cirsium) that bloom the second year after germinating and there are several native monocarpic plants (they bloom once, then die—see the answer to a previous question) that bloom after the plants are several years old (the century plants—Agave americana and Agave parryi, for instance). Another native plant that lives a long time before it blooms is Frasera speciosa (monument plant) which may wait for 20 to 40 years before it blooms and dies. Many of these plants may bloom simultaneously. This same phenomenon also happens with the non-native bamboo species that may bloom only every 40 to 80 years.
So—I do not know of any native North American plant that is night-blooming and flowers every five years, nor could I find any non-native plant with these features. If you know of one, or if you have any more information about such a plant, please let us know.

Now, let's delve into the information provided in the article about a night-flowering plant that blooms every five years. The article discusses a question posed to "Mr. Smarty Plants," a free service provided by the Lady Bird Johnson Wildflower Center. The question is about a plant that flowers at night but only once every five years. Mr. Smarty Plants mentions several night-blooming native flowers, such as Acanthocereus tetragonus (barbed-wire cactus), Peniocereus greggii (nightblooming cereus), Ipomoea alba (moonflower), Oenothera macrocarpa ssp. macrocarpa (Missouri primrose), and Mirabilis multiflora (Colorado four o'clock). However, none of these plants bloom exclusively every five years.
Mr. Smarty Plants also points out biennial plants that bloom every second year, monocarpic plants that bloom once before dying, and long-lived plants like Frasera speciosa (monument plant), which may wait for several decades before blooming. However, none of these precisely match the criteria of being night-blooming and flowering every five years. The article concludes by inviting readers to provide more information if they know of such a plant.
This detailed response showcases the expert's knowledge of various plant species, their blooming habits, and the factors influencing their flowering cycles. The inclusion of specific examples adds credibility to the information presented, reinforcing the depth of expertise in the field of botany.
