ArborNote’s Tree of the Week is the Taiwan cherry tree (Prunus campanulata). This species of cherry is native to Japan, Taiwan, southern and eastern China and Vietnam. It is a large shrub or small tree, growing 10–26 ft tall. In late winter, it produces one-inch, bright pink flowers on its naked branches. It is widely grown as an ornamental tree, and a symbol of Nago in the Ryukyu Islands of Japan. It is the host of larval Chrysozephyrus nishikaze, a butterfly species endemic to Taiwan and highly important to their continued survival. It is also one of the many cherry blossom trees that bloom early. Their seeds portray a physiological and morphological dormancy that is broken when exposed to cold and warm temperatures before germination.
