Bauhinia blakeana 洋紫荊 is sterile. That means it cannot reproduce using seeds and flowers. Therefore, if you observe a B. blakeana after flowering, no fruit pod will be formed. It is reproduced by artificial propagation, such as breaking off a branch / root and grow into a new plant.

If you really can see fruit pods on a tree, it is definitely not B. blakeana. It may be Bauhinia purpurea 紅花洋蹄甲, or other species within the Bauhinia genus.
Bauhinia is a genus of more than 200 species of flowering plants in the subfamily Caesalpinioideae of the large flowering plant family Fabaceae, with a pantropical distribution. The genus was named after the Bauhin brothers, Swiss-French botanists.
Many species are widely planted in the tropics as "orchid trees", particularly in northern India, Vietnam and southeastern China. In the United States of America, the tree grows in Hawaii, coastal California, Texas, Louisiana, and Florida. Bauhinia blakeana is the floral emblem of Hong Kong, and a stylized orchid tree flower appears on the Hong Kong flag.
