Trumpet Vine (Campsis Radicans) アメリカノウゼンカズラ

英語の後に日本語が続きます。

The trumpet vine (Campsis radicans) is native to eastern North America, imported to Japan during the Taisho period (1912-1926) for ornamental purposes. Its Japanese name is "amerika nozen kazura," which translates into "American trumpet vine," because Japan has two trumpet vines, the American trumpet vine (Campsis radicans) and the Chinese trumpet vine (Campsis grandiflora). Both resemble each other but the American one (Campsis radicans) has longer and thinner flower tubes than the Chinese counterpart. 

The phrase "nouzen kazura," which is contained in the Japanese name of both trumpet vines, means "vine blooming towards the sky." The bright orange flowers literally bloom towards the sky.

Persian Silk Tree (Albizia Julibrissin) ネムノキ（合歓木）

英語の後に日本語が続きます。

These are flowers of a Persian silk tree or pink silk tree (Albizia julibrissin). Persian silk trees fold their leaves during the night, which makes them look asleep, so they're called in Japanese "nemu no ki," which translates to "sleeping tree."  

A Persian silk tree is popular in Japan as suggested that it's a kigo* for summer. It's also often used as a theme for paintings, such as the one in the last photo "Sparrow in a silk tree" by Keibun Matsumura at Tokyo National Museum.

* Kigo are words or phrases that are associated with a particular season in haiku or Japanese poetry.

African Iris (Dietes Bicolor) ディエテス・ビコロル/オキナワシャガ

英語の後に日本語が続きます。

It looks like smiling to you, doesn't it? This is an African iris (Dietes bicolor). When seeing it for the first time, I didn't use Google Lens yet, so I did research using several keywords in Japanese, such as "flower," "white," and "look like a smiling face," which generated only one hit, "African iris." African irises are native to, and very common in, South Africa while in Japan, not the flowers but the sword like leaves are used for Japanese flower arrangement.

Pomegranate (Punica Granatum) ザクロ（柘榴）

英語の後に日本語が続きます。

The pomegranate (Punica granatum) originated in the region spanning from the west to south Asia to the Middle East. It produces bright orange flowers in June and fruits that contain ruby-like edible seeds and pulp from September to October in Japan. 

The flowers always cheer me up with their bright orange while making me chuckle with their unique shape after petals fall off, which looks like an octopus sausage, i.e., a sausage cut to look like an octopus, often seen in children’s Bento lunches in Japan. BTW, octopuses have no legs but only arms.

If you've never seen a sculpture of a pomegranate fruit made of agate and ruby, read this post! You should be surprised by how real it looks!

Apple Mint (Mentha Suaveolens) アップルミント

英語の後に日本語が続きます。

I always felt something was wrong when passing by them and I get it today. They're apple mint growing on the sidewalk. Did someone plant them there? Or did they come from somewhere and are they now growing wild? I've just started to grow lemon balm and chocolate mint myself, so I couldn't imagine herbs growing wildly. But I was wrong. The apple mint was so invasive that many websites advise against planting in the ground.

Double Flowered Fish Mint 八重咲きのドクダミ

英語の後に日本語が続きます。

Fish mints (Houttuynia cordata) are native to Asia and can be found across Japan. Those in the post are specifically double-flowered fish mints (Houttuynia cordata var. Plenus), one of my favorite plants! Fish mints produce beautiful white flowers from May to August in Japan although what look like petals are actually bracts as those of Cornus kousa are. 

Fish mints are used in Chinese medicine and in Japan, fish mint tea is said to be effective for skin problems. I suffered from severe acne in my teenage years so my late maternal granny sometimes sent me fish mint tea bags. I don't know if they were effective but I believe that thanks to the tea, I have no acne or any serious skin problems now.

Popcorn Hydrangea (Hydrangea Macrophylla Ayesha) ウズアジサイ（渦紫陽花）

英語の後に日本語が続きます。

They're one of my favorite hydrangeas, popcorn hydrangea (Hydrangea macrophylla Ayesha). Needless to say, the hydrangea is named after the shape of its sepals, which resembles that of popcorns.

Hydrangea 'Magical Revolution' マジカルレボリューション

英語の後に日本語が続きます。

Hydrangea macrophylla 'Magical Revolution' is really magical from two perspectives. Firstly, its spectacular, color-shifting transformation. The hydrangea changes from pale pink, blue, and green in early summer to red toward autumn. (Scroll down!) Secondly, its long life! The hydrangea's sepals (not petals!) are so sturdy that they can bloom for two to three months while changing color.  

It changes color to red in autumn due to increasing anthocyanin resulting from a change in the temperature and/or the amount of ultraviolet radiation. For whatever the reason, the hydrangea is just magically amazing.
