I have this tree planted out and it is truly hardy . It isn't moisture sensitive (BUT always best planted in well drained areas). It is also very very pretty and a fav of mine . It seems to take sun well for it's species. The colors are VERY nice all season and it is a very fast grower.. This is a good substitute for the A.s Aureum or easier to grow A.s. Autumn Moon . It is a very "I can take care of myself" tree that even a brown thumb should be able to easily grow. If you like Aureum but are a novice or don't have time to baby your JMs this is a great substitute .. It is one of my current top ten cultivars although hard to get I have some on hand most times .. as all shirasawanum it grows slowly and is a small tree so buying a larger one is a good idea when larger ones are available
Winter Hardiness: Zone 5 - Down to -20°
Summer Hardiness: Tree will be planted in full sun
