Seed of Carpinus shensiensis was probably first introduced to the West by Roy Lancaster through his contacts with the Shanghai Botanic Garden, in 1982. This material was collected on the Qin Ling Shan in southern Shaanxi, and specimens from it are growing at Wakehurst Place and at the Hillier Gardens, where it is 6 m tall. Other introductions followed, and it is now available commercially from several sources in Europe. Numerous branches from low on the trunk give it a broad, rounded outline, at least when young. The narrow leaves flush red in spring and change to pinkish shades in autumn (Mallet Court Nursery catalogue 2006).
