Juglans regia 'Zijing' (Chinese: 紫京彩叶核桃树,紫京核桃树) is a cultivar of walnut developed in Beijing, China.[1] IT was developed frommother trees of purple-leaved walnut, which was found in the mountains of Qingshui, Mentougou District, China in 1998.[2]
J. regia Zijing was cultivated by Wang Xiupo.[1][3] On 17 October 2017, Wang obtained the certificate of plant variety rights from the State Forestry Administration of China.[4] Because J. regia Zijing trees have five major purple features: female flowers, leaves, peel, and kernels, they are also called Wuzi Walnut (五紫核桃).[5] The trees are mainly distributed in Beijing International Walnut Manor.[1]
They grow at an altitude of about 800 meters, J. regia Zijing trees have strong resistance and adaptability, and are adapted to temperate climate regions.
Because walnuts are light-preferring plants, it is better to use south-facing slopes in the Northern Hemisphere.[1]

Weeding should be performed frequently, and drainage is important during rainy seasons. They further require protection from pests and diseases from June to July.[6]
Scion collectionedit

Grafting timeedit
Grafting is appropriate from the end of May to the beginning of July.[6]
Bacterial root rotedit
Bacterial nuclear root rot, caused by Sclerotinia sclerotiorum, causing seedling root and lateral root cortex decay, resulting in the death of J. regia Zijing. Prevention and treatment involve selecting nursery lands, managing soil water content, disinfecting seeds and soil guality.[6]
