Weigela subsessilis

About

Weigela subsessilis, the Korean weigela, is a species of flowering plant in the honeysuckle family native to the Korean Peninsula. It can be found on most of the mountains of Korea, except for the northern sides because the temperatures are very low. As the species is highly resistant to shade, cold, salt and even pollution, it is also found in deep forests or near the seas.
