Yunnan: Lincang, Yunxian, Yongbao zhen
An oddity native to Yunnan, and sporadically cultivated, for both its immature and grown fruits. They're traditionally eaten raw with chili powder/salt as a snack, much like green mangos are eaten in Thailand. Should prove reasonably hardy. We identified these by fruit morphology, but there are other clear differences too. This particular collection is very aromatic, but sadly also very shy to set fertile seeds.
Very scarce! 6 seeds per package.
