Somei-yoshino are the most popular cherry blossoms in Japan. They bloom all at once in spring, and it was said that this was because all the trees shared the same genes, meaning that they are "clones". The Forestry and Forest Products Research Institute focused on one DNA section and were able to confirm this with a high level of precision. What's more, a new theory suggests that the very first tree is in Ueno Park. Join us as we take a closer look at the origin of the beautiful Somei-yoshino!
