Once thought to be a distinct species. Leaf shortly stalked, green, often with three or more distinctly stalked leaflets. Its true origin was not suspected until a similar sport was found growing on ordinary A. palmatum
. There are two examples at Westonbirt, Glos., about 50 ft high.The typical A. palmatum
and most of the green and purple varieties are quite hardy in the south of England. Yet they are not very frequently seen in good condition. Although tolerant of shade, they are best in a bright position sheltered on the north and east sides, and in a good loamy or peaty soil. Perhaps their greatest drawback is their susceptibility to late spring frosts; it is not unusual to see the young growths cut back once or twice in the spring, and whilst the vigorous green, purple, and red varieties recover, that is fatal to the permanent success of the more delicate forms with the most exquisite colouring and cutting. Cold, drying winds are also detrimental to the unfolding leaves of these more delicate forms. Another source of failure is due to their being grafted on strong, ill-fitting stocks. Several forms, hitherto failures, have been found to succeed on their own roots.
