This was followed in 1829 by the five-volume Somoku Kinyoshu, which pictured over 1000 cultivars in the same Aucuba japonica ’Sun Dance’ format. These plants, as well as those selected for showy flowers were (and still are) grown in pots and admired individually rather than as part of a garden landscape. Most of these plants have been cultivated at Brookside Gardens for three years or more, and most have been observed in cultivation in Japan in several seasons as well.
