Hello everyone!
Ishigaki Island and its surrounding islands have a subtropical climate, which is rare in Japan. Because of this climate, there are creatures that are unique to that climate. The same can be said for plants.

 

For example, when we say mango or pineapple, we think of tropical fruits, right? Yes, they are.
Plants that are suited to the climate grow there. Ishigaki Island and the surrounding islands, which have particularly high biodiversity, are home to a variety of unusual plants.
In this article, we will introduce the plants that can be found on Ishigaki Island and its surroundings.

 

 

 

Characteristics and reasons for the plants on Ishigaki Island

 

As mentioned at the beginning of this article, the Yaeyama Islands, located at the southernmost tip of the South, belong to a subtropical climate. Therefore, various subtropical plants that can only be found on Ishigaki Island and its surrounding remote islands, Iriomote and Taketomi Islands, grow wild. The color, size, and visual impact of these plants are all unimaginable on the mainland.

 

There are so many beautiful and attractive flowers that you can enjoy just strolling around and looking at the plants.

Moon is also a member of the ginger family, Gingeraceae, and because it is a member of the ginger family, it grows toward the ground from a stem that burrows into the ground like ginger.

 

It is called "false stem" because the above-ground growth looks like a stem, but it is not a true stem.
This false stem grows up to about 2 meters and is very sturdy due to its fibrous nature. <

The bright red flowers bloom from early spring to early summer, heralding the arrival of summer to the locals. They are extremely beautiful flowers, but as it is said that typhoons visit when the deigo is in full bloom, the best time to see them is before the summer season, when typhoons are frequent.

Adan is a plant that grows near the coast in tropical and subtropical regions. It is a tropical fruit with a distinctive pineapple-like visual. Many places on Ishigaki Island and Miyako Island entertain tourists with dishes using adan leaves and shoots.

 

Adan berries, as pineapple-like as they look, give off a pineapple-like sweet and sour aroma. However, as mentioned above, the leaves and shoots of adang are mainly used for cooking.

 

The first reason for this is that the berries are very hard. Adan berries are 4 to 6 cm in diameter, and are tightly packed together. The skin is so hard that it is difficult to pull the fruit out. They also need to be drained, otherwise you will feel a tingling and numb sensation in your mouth. Because of the above-mentioned cooking processes and complications, they are not often used in cooking.
