Trivia about cherry blossoms: A collection of fun facts to make spring hanami even more enjoyable (11–20)
There is a cherry tree that blooms green flowers.
When we think of cherry blossoms, we often picture them tinting spring a beautiful shade of pink.
Cherry trees actually come in many varieties, and among them are some unusual ones that bloom green flowers, quite different from that image.
The cherry tree that bears green blossoms is called Gyoikō; it’s a type of double-flowered cherry whose blooms gradually shift from green to yellow, and it is said to have originated from cultivation at Ninnaji Temple in Kyoto.
Although they are flowers, they also retain leaf-like traits such as chlorophyll, making them a cherry blossom that offers a glimpse into the process of plant evolution.
March 27 is Sakura Day.
The blooming of cherry blossoms signals the arrival of spring.
Every year around late March, we start hearing announcements that the cherry blossoms have begun to bloom.
The sentiment behind “Sakura Day” on March 27 is also tied to the blooming of cherry blossoms.
Established in 1992 by the Japan Cherry Blossom Association (a public interest incorporated foundation), Sakura Day comes from a wordplay that converts the word saku (to bloom) into numbers.
When you turn saku into numbers and multiply them, 3 × 9 = 27.
From this, March 27 was chosen, aligning it with the shichijūni-kō (the 72 microseasons) period called sakura hajimete hiraku—meaning “cherry blossoms begin to open.” By the way, sakura hajimete hiraku is read just like that in Japanese.
Through Sakura Day, the aim is to foster interest in cherry blossoms, Japan’s representative flower, and to promote the creation of a nation rich in flowers and greenery.
Cherry tree branches become prone to rot when cut.
If you’re thinking of cutting back those growing cherry branches, wait a moment! Cherry trees are delicate, and cutting their branches can make the cut areas prone to rot.
If fungi enter through the cut, they can spread throughout the tree and even kill it.
On the other hand, leaving overgrown branches unattended can lead to disease and create branches that don’t get enough sunlight.
To avoid this, it’s important to think carefully about where you cut and to handle the cuts properly afterward.
It’s also crucial to pick the right timing for pruning, so be sure to research thoroughly and care for the tree accordingly.
Cherry trees viewed during cherry-blossom viewing don’t produce cherries.
Cherry-picking season starts around late June.
Many of you may have tried cherry picking at least once, right? However, the cherry trees that bloom in parks for hanami don’t produce edible cherries.
They may bear small red, berry-like fruits, but they aren’t suitable for eating.
Most of the cherry trees seen during hanami are Somei Yoshino, a cultivar created through selective breeding, and they’re all clones with identical genes.
It’s said that Somei Yoshino trees with the same genetic makeup cannot produce fruit among themselves.
If there are different types of cherry trees nearby, such as wild mountain cherry (Yamazakura), and proper pollination occurs, Somei Yoshino can bear fruit—though whether those fruits are suitable for eating is another matter.
Cherry blossoms are plants in the rose family.
Botanically, cherry trees belong to the rose family (Rosaceae).
Cherry blossoms and roses look different, and cherries don’t have thorns like roses.
The definition of Rosaceae includes having five petals and five sepals, with ten or more stamens.
Flowers like Somei-Yoshino have five petals, but double-flowered cherries have more than five.
Even so, plants that have arisen through breeding or environmental adaptation are still classified in the rose family.
Besides cherries, there are about 2,500 species in Rosaceae, including apples, strawberries, and loquats.
Many flowers in the rose family are beautiful, and many of their fruits are delicious.
Somei Yoshino is a type of Japanese cherry tree and accounts for about 80% of the varieties.
In spring, beautiful pink cherry blossoms bloom in towns and parks, don’t they? Most of those blossoms are a variety called Somei Yoshino, which makes up about 80% of the cherry trees in Japan.
Somei Yoshino originated in the Edo period, and because all the trees are propagated from the same original tree, their blooming patterns and colors are very uniform.
When everyone goes cherry-blossom viewing together, the park’s trees can look like a pink carpet.
When spring comes, try finding Somei Yoshino blooming on your way home from school or near your house, and compare the number and shapes of the flowers!
Toyotomi Hideyoshi was the first to start the current style of cherry blossom viewing.
When cherry blossoms reach their peak, many people probably look forward to hanami.
Under beautifully blooming cherry trees, they enjoy delicious food and good conversation.
It’s said that Toyotomi Hideyoshi held an event that closely resembles today’s hanami.
Before then, there were elegant gatherings where aristocrats composed poems while viewing plum blossoms, a culture unique to the nobility.
However, Hideyoshi reportedly planted 700 cherry trees on Mount Daigo and hosted the Daigo no Hanami, inviting 1,300 guests.
Serving renowned sake and confections presented from around the country, it was a lavish, resplendent feast-like celebration.
In the Edo period, hanami is said to have spread among the common people.
Japan’s oldest cherry tree is the Yamataka Jindai-zakura in Yamanashi Prefecture.
Cherry blossoms brighten spring across Japan, and among them are trees that seem to have watched over the nation’s history for centuries.
Here’s a bit of trivia about where the oldest surviving cherry tree stands and how long it has lived.
Said to be Japan’s oldest cherry tree is the Yamataka Jindai-zakura on the grounds of Jissō-ji Temple in Yamanashi Prefecture, estimated to be about 2,000 years old.
It’s an ancient Edohigan cherry designated as a National Natural Monument, with a legend that it was planted by the hero Yamato Takeru.
It’s a beloved local spot, especially when the cherry blossoms bloom in step with trumpet daffodils in the spring.
The standard for full bloom of cherry blossoms is when over 80% of the flowers have opened.
Sometimes we can feel the arrival of spring from news reports and other information about cherry blossoms.
When the cherry blossoms are in full bloom, some people may find their hearts lifting, don’t you think? A tree is said to be in full bloom when more than 80% of its blossoms are open.
Observations are made based on the condition of a designated “standard tree” in each prefecture.
When 5 to 6 flowers open on the standard tree, it’s considered the start of blooming; when about 30% are open, it’s called “30% bloom” (san-bu zaki); and when half are open, it’s “50% bloom” (go-bu zaki).
Incidentally, there is at least one standard tree in every prefecture, with a total of 58 across the country.
In large areas like Hokkaido and Okinawa, there are several standard trees.
The origin of the term sakura, meaning a fake customer or shill, comes from how they appear suddenly like cherry blossoms and then disappear just as quickly.
People who pretend to be audience members but aren’t genuine fans—planted shills in theater audiences and the like—are called “sakura” in Japanese.
This term actually comes from the image of cherry blossoms.
Its origin dates back to the Edo period, when certain people in the audience would call out to liven up the performance for the actors.
Because they would brighten the atmosphere in a flash and then slip away, their behavior was likened to cherry blossoms that bloom brilliantly and fall just as quickly, and they came to be called “sakura.” Be aware that such practices can constitute an offense if carried out in a malicious or fraudulent manner.
