View Plant | Great Plant Picks Green Japanese Maple "osakazuki" This lovely upright grower develops the best fall foliage color in full sun to open shade. Japanese maples are surprisingly flexible in their soil requirements. Although they will grow best in a rich well-drained soil, they will also do well in sandy soils and clay. ‘Osakazuki’ is very resistant to the leaves burning at the tips during the summer, but regular watering during dry weather helps maintain the tree at its best. .
