Japanese Ternstroemia (Ternstroemia Gymnanthera) 木斛（モッコク）

英語の後に日本語が続きます。

Japanese ternstroemia trees are said to be the king of garden trees in Japan and there's a reason for that. They produce tiny buds in early June, which look like cat's paws, and then beautiful male and hermaphroditic flowers from late June to July. And in autumn, they bear fruits, which turn from green to red, and some of them stick out bright red seeds like tongues after cracking. Japanese ternstroemia trees bring us happiness throughout the year.

Plantain Lily (Hosta) ギボウシ（擬宝珠）

英語の後に日本語が続きます。

Plantain lilies are native to eastern Asia and about 20 types of Hosta can be found across Japan, producing pale pink flowers from June to August. Their young leaves and petioles are edible, used in various Japanese dishes such as salads, pickles, and miso soup.  

The lily's Japanese name is "giboshi" or "giboshu," a type of ornamental finial used on Japanese railings (no English translation), after the shape of the lily's bud looking like the finial.

Coppertips (Crocosmia x Crocosmiiflora) 姫檜扇水仙（ヒメヒオウギスイセン）

英語の後に日本語が続きます。

The Crocosmia x crocosmiiflora is a cross breed of Crocosmia aurea and Crocosmia pottsii, both of which are native to South Africa. The Crocosmia x crocosmiiflora was introduced to Japan at the end of the 19th century for ornamental purposes but because of its invasiveness, the plant has been designated as an invasive alien species by some prefectures.

Its Japanese name is "hime hiogi suisen," which translates into "princess blackberry lily narcissus," because of the resemblance of its leaves to those of blackberry lilies and the bulbs to those of narcissus. The term "hime," which means princess, is used to describe its smallness.

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

A weevil was resting on, and a bee was gathering pollen from, flowers of apple mints in my neighborhood. They're growing on the sidewalk. I have no idea about how they got there.

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.

Coral Honeysuckle (Lonicera Sempervirens) 突抜忍冬（ツキヌキニンドウ）

英語の後に日本語が続きます。

The coral honeysuckle (Lonicera sempervirens) is native to North America, came to Japan during the Meiji period (1868-1912), and can now be found across Japan. One of its features is its bright red and orange blooms during May to September in Japan, which is shown in its English name while another is in its Japanese name "tsukinuki nindou," which translates into "penetrating honeysuckle," after the stem looking like penetrating a leaf.

Oriental Arborvitae (Platycladus Orientalis) コノテガシワ（児の手柏）

英語の後に日本語が続きます。

I've always wondered what they are when passing by them for the last couple years and today, I did research, finding they're cones of the Oriental arborvitae. The tree is native to China and can be found across Japan.  

The Oriental arborvitae is hermaphroditic, producing orangish beige male and female flowers on the same tree from March to April, which I completely missed this year.

Lily (Lilium) ユリ（百合）

英語の後に日本語が続きます。

Lilies are native to Asia, Europe, and North America. There are more than 100 wild species around the world and 15 in Japan, producing flowers in various colors from May to August in Japan, of which I've seen pale pink, yellow (scroll down), red (Blackout red), and orange (Thunberg orange). The lily bulb (mainly the Maximowicz's lily's [Lilium leichtlinii]) is edible, often steamed, sauteed or deep-fried (i.e., tempura), as a seasonal delicacy in Japan. So, if you have a chance to come to Japan in winter, don't miss eating lily bulb or "yurine" TEMPURA to enjoy its soft and fluffy texture.  

The lily's Japanese name is "yuri" after the term "yusuri," which means shaking or trembling, because lilies shake and/or tremble in the wind as their stems are thin but the flowers are big.

Various Lacecap Hydrangeas 額紫陽花（ガクアジサイ）いろいろ

英語の後に日本語が続きます。

It's almost impossible to classify lacecap hydrangeas (Hydrangea macrophylla f. normalis) based on color. Each one has cream, yellow, blue, purple, green, pink, and red fertile flowers surrounded by green, pink, blue, purple, red, and even white sterile decorative sepals, changing their gradients as time passes. It's reasonable that one of its Japanese names is "shichi henge," which translates into "seven changes." To see lacecap hydrangeas in pink or purple, read this post!

Chinese Spiranthes (Spiranthes Sinensis) ネジバナ（捩花）

英語の後に日本語が続きます。

The Chinese spiranthes (Spiranthes sinensis) is native to Eurasia and Australia and can be found across Japan, producing pink flowers from May to August. As a plant found across Japan, the Chinese spiranthes is used as kigo, i.e., a word or phrase associated with a particular season in haiku or Japanese poetry, for mid-summer, the period from June 6 to July 6. Interestingly, some spiral clockwise while others counter clockwise. There is no established theory to explain what determines the direction of the spiral.

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.
