So happy to make my first official publication of 2026 in @thebkmagazine.bsky.social, which includes my poem, "Nyctinasty" in the new issue!

How Plants Sleep: Oxalis triangularis 🌿

Oxalis triangularis shows nightly “sleep” movements (nyctinasty) — leaves fold down after lights-off and rise again after lights-on.
5-day timelapse.

Nice shot and the position of the petals suggest that this is a member of the Asteraceae family. If so the petals follow the sun across the sky (heliotropism) and also close at night and open back in the day (nyctinasty)
So a pretty clever plant 😄

Very interesting post Mick 🤩 Have had those flowers, just for the summer time, but never heard the term nyctinasty, in Finnish nyktinastia. Love to learn, so big thanks. And beautiful shots as well 👌

Gazania flowers in my garden yesterday.
At night or on dull or cloudy days, Gazania flowers close their blooms in response to the lack of sunlight, a natural behaviour called nyctinasty. A response to the daily cycle of light and darkness.

A picture of a garden pot containing a Gazania Big Kiss White Flame plant. All of the flowers are closed. At night, Gazania flowers close their blooms in response to the lack of sunlight, a natural behaviour called nyctinasty. It is a type of plant movement in which leaves or petals close in response to the daily light-dark cycle, essentially a "sleep" movement. It's a nastic movement, meaning it's not related to a directional stimulus like the sun's rays, but rather a rhythmic, internal response to the plant's circadian clock. A picture of a garden pot containing a Gazania Big Kiss White Flame plant. It has many daisy like flowers in bloom with large pink and white petals and a yellow centre. It has dark green leaves and some buds yet to flower. A picture of a garden pot containing Gazania Big Kiss Orange Flame plant. It has four large daisy like flowers in bloom with bright orange petals and a yellow centre. It has dark green leaves and some buds yet to flower.

Me: You better not be any kind of nasty when I get home.
The plant I got today:
A photo of a calanthea plant sitting on a shelf. Its leaves are tucked up and pointing at the ceiling. It tucks up like this every night and then lets the leaves down again in the morning to look for light, a process called nyctinasty.

Oxalis are otherwise easy and lovely houseplants. They like a home kept on the cool side. Both flowers and leaves fold at night, a phenomenon called nyctinasty, a movement related to the onset of darkness.Mar 21, 2025

A new post on my nature-ish blog - Nyctinasty of Chicory:

chicory flower at sunrise with direct light and partially open. The background is blurred with a meadow and a couple of branches overhead. The image is processed with textured overlays, vignetting, and contrast to look slightly like a painting.

I learned today while researching that when flowers close up at night, that's called "nyctinasty," pronounced nik-tuh-nas-tee!

I learned another new plant-related term today: nyctinasty. This is where petals close at night. Examples include daisies, tulips, crocuses and some poppies, like these lovely California ones we have in the garden :)
A beautiful orange and yellow California poppy - these flowers are nyctinastic (ie the petals close at night).

Urban deciduous trees can retain canopy beneath a street lamp for days or weeks longer (delayed senescence). Evergreen plants maintain other light signaled responses (delayed nyctinasty here, the dark side has “closed” leaflets typical of nighttime). Both likely quality, not quantity, of PPFD.

Geranium pyrenaicum, Hedge Crane's-bill. Nyctinasty, circadian rhythm, falling asleep in response to encroaching crepuscule.

Wood sorrel is currently blooming in many parts of the country.

These lovelies are at our #PloraWood in the Borders.

Wood sorrel leaves fold up at night or during heavy rain, a behaviour called nyctinasty.

They Move A Bunch! 🌿 – Their leaves shift positions throughout the day, folding upward at night like hands in prayer—hence the name! This movement, called nyctinasty, is a response to light changes.

During daylight, the leaves perk up as they take in sunlight (photonasty), maximizing their exposure for photosynthesis—their way of making food.

As night arrives and temperatures shift, they begin to relax and droop to conserve energy and reduce water loss (nyctinasty).

This daily dance is part of a natural process called "photonasty & nyctinasty," a response to light & temperature changes.

In this case it’s nyctinasty, a form of phototropism I think. The movement is controlled by chemical gradients that are produced by exposure to light. No brains required.

Texts between ed and stede: stede: good morning! 🌞/Ed: horrific emoji choice, but good morning/stede: 🌷flowers like tulips, crocuses, hibiscus and poppies close at night. this behavior is called nyctinasty!/ed: me too, the fuck/stede: Maybe you’re a tulip! texts between ed and stede: stede sends ed a picture of his face photoshopped onto a tulip/ed: yeah maybe ed’s private twitter: a photo of jerry from tom and jerry looking smug, captioned “i’d like to do the nyctinasty with him” stede’s private twitter: prettier than any flower 🌷
