What is Japanese spikenard?
Udo ( Aralia cordata ) is an upright plant growing up to 2 to 3 metres in height, native to Japan, Korea and eastern China. The plant yields new shoots every spring, which are blanched and then eaten as a vegetable. The young shoots have a strong yet pleasant distinct aromatic flavor. The edible stem is sometimes boiled and served in miso soup. They also may be cooked like asparagus.
