Bok choy Bok choy Bok choy, pak choi or pok choi (; "Brassica rapa" subsp. "chinensis") is a type of Chinese cabbage. "Chinensis" varieties do not form heads and have smooth, dark green leaf blades instead, forming a cluster reminiscent of mustard greens or celery. "Chinensis" varieties are popular in southern China and Southeast Asia. Being winter-hardy, they are increasingly grown in Northern Europe. This group was originally classified as its own species under the name "Brassica chinensis" by Linnaeus. Other than the ambiguous term "Chinese cabbage", the most widely used name in North America for the "chinensis" variety is "bok choy"
Bok Tower Gardens only. To make an appointment, the Bok Tower librarian should be contacted. The Chao Research Center Archives was formed in 2008, after a generous donation made by the Ting Tsung and Wei Fong Chao Foundation. With this donation, space was made available on the second floor of the Singing Tower to accommodate a growing need for delicate archival documents. The Chao Research Center Archives stores the official archives of Bok Tower Gardens along with other significant collections. These significant collections include the Nellie Lee Bok Collection, American Foundation Collection, and Edward Bok Newspaper Scrapbook Collection. The Nellie Lee Bok Collection
