Bitter Gourd (Momordica Charantia) ゴーヤ（苦瓜）

英語の後に日本語が続きます。

Bitter gourds (Momordica charantia) are native to tropical Asia, came to Okinawa, i.e., one of the southern islands in Japan, in the early 15th century, and can now be found across Japan. The gourds are monoecious, which means they produce yellow, male and female flowers from July to August but it's easy to tell because the male has the yellow center while the female has the green center. They usually produce male flowers first to ensure the safe fertilization of the female ones. So, the ratio of male to female in early summer is about 10:1. 

Ripe orange gourds (scroll down) are edible including the red seeds and even jelly like stuff around the seeds.

Japanese Cornel Dogwood (Cornus Officinalis) サンシュユ（山茱萸）

英語の後に日本語が続きます。

The Japanese cornel (Cornus officinalis) is native to China, Korea, and Japan and can be found across Japan. The tree produces umbels of bright yellow flowers from March to April and berries that get redder from October to November. 

The bright yellow of Japanese cornel flowers is called a "vitamin color" in Japan because it's said to energize people, which I believe is true. In spring, many stop in front of the trees to look at their pretty flowers talking about the joy of spring but surprisingly and sadly, most don't know the Japanese cornel. The Japanese cornel is one of the most underestimated trees because of their blossoming at almost the same time as cherry and Japanese apricot trees.

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;
