Robert Fortune, the great explorer of the Royal Horticultural Society, made four trips to China and introduced many fine plants to England. In 1846, he brought twenty-five of the finest tree peonies ever to come out of China. Among these were 'Atrosanguinea,' 'Berenice,' 'Bijou de Chusan,' 'Dr. Bowring,' 'Globosa,' 'Glory of Shanghai,' 'Lord Macartney,' 'Pride of Hongkong,' 'Robert Fortune,' 'Samarang,' and 'Zenobia.' These were enthusiastically received and quickly propagated, so that both British and continental nurseries cataloged them in some quantity in the 1860's.
