Prunus yunnanensis

Prunus yunnanensis, the Yunnan cherry (Chinese: 云南樱桃) is a species of Prunus native to Yunnan, Guangxi, Sichuan and adjacent provinces of southeast China, preferring to grow at 1900–2600 m. The white flowers open at the same time as the leaves bud out, or very slightly before. It flowers from March to May, and fruits two months after.

Notes
  1. 西南樱桃 seems to most often refer to Cerasus duclouxii.
gollark: Alas, the random number generator does not know of such things as "words".
gollark: Gaaaah. I missed a Silver in the cave because I didn't recognize the description.
gollark: Some people (like me) really like very long ones.
gollark: Messy dragons are cool and arguably valuable too.
gollark: I think that "collect cool dragons" is a perfectly viable strategy in a game about collecting cool dragons.
