Crepe Myrtle (Lagerstroemia Indica) サルスベリ（百日紅）

英語の後に日本語が続きます。

Crepe myrtle (Lagerstroemia indica) is native to China, coming to Japan before the Edo period (1603 - 1867) and can now be found across Japan. The tree produces flowers in various colors, white, pink, and red. Its leaves turn orange and red beautifully in autumn and the dark brown fruits are also beautiful.   

The crepe myrtle has two names in Japan, "saru suberi," which translates to "monkeys slip" because of its slippery bark, on which even monkeys (are said to) slip, and "hyaku jitsu ko," which translates to "red for one hundred days," after that the crepe myrtle flowers bloom for a long period of time.

According to Flower Meanings, the crepe myrtle flower means;
- Prosperity;
- Good luck;
- Chastity;
- Good luck in love and marriage; and
- Marital fidelity.

But here in Japan, it means:

- Eloquence;
- Charm and;
- Carelessness.

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。

Persian silk trees or pink silk trees (Albizia julibrissin) are native to southwestern and eastern Asia and can be found across Japan, producing "silk-like" pink flowers from June to July in Japan. They fold their leaves during the night, which makes them look asleep, so their Japanese name is "nemu no ki," which translates to "sleeping tree."  

A Persian silk tree is popular in Japan as suggested by it being 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.

Persian silk trees are in the Fabaceae family, so produce seed pods which resemble flattened bean pods (scroll down).

Purple Heart (Tradescantia Pallida) ムラサキゴテン（紫御殿）

英語の後に日本語が続きます。

Purple heart (Tradescantia pallida) is native to Mexico, came to Japan in around 1955, and can now be found across the country. The plant produces purple flowers from June to September, which creates a beautiful contrast with its deep purple leaves and yellow stamens.  

Speaking of purple, Japan has several types of purple, e.g., Kyo murasaki or Kyoto purple and Edo murasaki or Tokyo purple. Both are made from purple gromwell (Lithospermum erythrorhizon), but Kyoto purple is older and more reddish than Tokyo purple.

I compared the two purple colors, wondering which purple the Tradescantia pallida leaves are, but couldn't decide. To me, these leaves look just between Kyoto and Tokyo purple. So, I have decided to call it "Nagoya" purple, i.e., the purple of a city between Kyoto and Tokyo!😆

Those in these photos grow in a vacant lot in Central Tokyo on which a house or something is to be built. This means they should be removed soon.

Meadowhawk (Sympetrum) 赤とんぼ 「夕焼け小焼けの♬」

英語の後に日本語が続きます。

There are about 20 types of meadowhawk (Sympetrum) in Japan and they're all called "red dragonflies." And I believe that these photos are of two of them; noshime dragonfly (Sympetrum infuscatum) and crimson dropwing (Trithemis aurora). 

Red dragonflies are so popular in Japan that they have a song for children titled "Red dragonfly," which is very famous. 

If you're interested in blue dragonflies, read the following posts: Blue-tailed forest hawks and White-tailed skimmers.

英語の後に日本語が続きます。

The Chinese parasol tree (Firmiana simplex) is native to southern China and southeast Asia and can be found across Japan, producing flowers from May to July and seedpods in autumn. 

I've walked around the tree many times but it wasn't until I saw the seedpods and their pea-like seeds scattered on the ground that I noticed the tree's presence. The seeds are edible when roasted.

The moth looks like a small purplish gray (Iridopsis humaria) but it can't. A small purplish gray exists in only North America according to information on the internet.
