Dawn Redwood (Metasequoia Glyptostroboides) メタセコイア

英語の後に日本語が続きます。

Some plants are aesthetically pleasing throughout the year and dawn redwood trees (Metasequoia glyptostroboides) are one of them. In autumn, their leaves create a gorgeous view (scroll down) while from spring to summer, the leaves create a magnificent, fresh green view and the small deep green cones make me chuckle with their matcha chocolate like appearance. 

The dawn redwood is a living fossil species. They're tall and their leaves look like fern leaves, which explains to me why I feel like I were in the dinosaur era under the trees. If you're interested in their annual life cycle, scroll down!

Goldencup St. John's wort (Hypericum Patulum) キンシバイ（金糸梅）

英語の後に日本語が続きます。

Goldencup St. John's wort (Hypericum patulum) is native to China, coming to Japan in around 1760 and can now be found across the country. It produces bright yellow flowers from May to July, which resemble the flowers of Chinese St. John's wort (Hypericum monogynum) but can be easily distinguished by the length of stamens. The stamens of Hypericum patulum are much longer than those of Hypericum monogynum.

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!

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.

Cogon Grass (Imperata Cylindrica) チガヤ（千萱）

英語の後に日本語が続きます。

(I believe that) they are cogon grass (Imperata cylindrica). The grass is native to tropical and subtropical regions of Asia, Australia, Micronesia, Melanesia, and parts of Africa and can be found across Japan. It produces fluffy, white seed spikes from May to June.

Cogon grass is one of the most invasive weeds with a plain appearance but has been deeply appreciated and utilized in Japan for a long time, even mentioned in Kojiki (i.e., an early Japanese chronicle of myths, legends, hymns, genealogies, oral traditions, and semi-historical accounts, composed in the early 8th century) and Man'yōshū (i.e., the oldest extant collection of waka or poetry in Classical Japanese, compiled at the end of the Nara period [710-794]). The plant was also eaten in Japan after the war.

The flower means "affectionate," "guardian deity of children," and "we all want to be together" in Japanese floriography.

Love-In-A-Mist (Nigella Damascena) ニゲラ（黒種草）

英語の後に日本語が続きます。

Love-in-a-mist (Nigella damascena) is native to the Middle East, the Mediterranean, and Southwestern Asia. The plant produces blue, pink (scroll down), purple, white (scroll down), and yellow flowers from April to July, which are distinguished from other flowers by their many long stamens. What appear to be petals are actually sepals as in the case of hydrangeas. 

The plant is also called "devil-in-a-bush" and some may wonder why it can be "devil-in-a-bush" and "love-in-a-mist" at the same time. The Hutchinson News (the relevant article is gone) gave me an answer. "The plant, when green and flowering, is called love-in-a-mist, but when the horned seed pods dry in the autumn, it changes, like Jekyll and Hyde, to the name of devil-in-the-bush." 

This is also true of Carolina cranesbill, which also has good and evil within them. If you wanna see an angel and a devil within Carolina cranesbill or its Jekyll-to-Hyde change, read this!!

Pink/Purple Lacecap Hydrangea ピンク・紫のガクアジサイ（額紫陽花）

英語の後に日本語が続きます。

Hydrangeas are pleasing with their colors and these pink and purple mountain hydrangeas in particular because the blooms have not only beautiful sepals (sterile flowers) but also pretty petals (fertile flowers). The 4th photo is a close up of the center part consisting of real (fertile) flowers, which are so tiny and so beautiful!  To see lacecap hydrangeas in other colors, read this post!
