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

i really just wanted to post the word nyctinasty

i have just been informed that:

Fun Fact: The California Poppy, California's state flower, closes its petals at night or during cloudy weather to protect its reproductive parts, a unique survival behavior known as nyctinasty.

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).

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.

A beautiful Daisy
Did you know a daisy closes up at night? This closing and opening of petals is a phenomenon called nyctinasty, where plant parts move in response to daily rhythms of light and darkness.

"Shylight" is more than just a light installation—it’s a captivating interplay of nature and technology inspired by nyctinasty, the phenomenon where flowers close at night for protection, Shylight captures the elegance of transformation and resilience. Artist: @studio.drift Video: @katch_katch

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

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.

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.

How Plants Sleep: Oxalis triangularis 🌿

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

Bindweed closes its flowers each afternoon, on cloudy days, or at night through a natural biological rhythm called nyctinasty. An individual bindweed flower lasts for just one single day. 💚

#AlphabetChallenge #WeekEForEphemeral
#Bloomscrolling #Flowers
#photography #ECK
An upright, eye-level close-up shows three morning glory or bindweed flowers (Convolvulaceae), two of them fully closed and another nearly fully closed, in a lush green environment. The cylindrical closed flowers are in the center, left, and upper right, while the nearly fully closed flower is in the center left, a short distance behind the others. The flowers, which grow on tall, thin stems, are soft pink and have five vertical folds. The stems, which are a translucent pale green, grow from the bottom right and curve to the upper left. At the base of each flower are two dark red-purple bracts, which are almost triangular and point upward, partially enclosing the lower part of the flower. Large, light green, heart-shaped leaves grow below and to the sides of the flowers. The green vegetation in the background is blurred and out of focus.

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 🌷

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.

I’m no clover, we just have similar leaves. A weed? I’ve been called worse, but I’m a NA native. Here’s a hint: I’m erect in youth, my seeds explode and my leaves do the nyctinasty. I’m Upright Yellow Woodsorrel

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