Ichang Lemon (Shangyuan)

Ichang Lemon is a natural hybrid of Ichang Papeda, identified in China at the beginning of the 20th century by F.N. Meyer, botanist and explorer for the USDA (U.S. Department of Agriculture).

The fruit is big (300gr +) and looks like a giant orange with yellow pulp. It is very juicy, acidic and aromatic.
The zest is an exceptional condiment, used for centuries as a perfume by the Chinese. Its scents are similar to those of Yuzu, but the abundant juice is more lemony.
It can be used like a lemon but also prepared like yuzu. Because it yields so much juice, it is very popular in jams, ice cream, and pastries.
Harvested in the fall.

The tree is vigorous, with large leaves and long thorns.
The Shangyuan cultivar is the least thorny and the least prone to alternation (less abundant harvest every other year).
