This a Very hardy cultivar. it can take sun but does better in a bit of shade.It simply glows all summer. The fall red is just an afterthought and a good one at that. I love this tree . It does great here and is really different for those unaccustomed to the multi cultivared world of JM's .. I mention this cause it is so easy to grow if this were your first "different" JM you couldn't do much better.
Winter Hardiness: Zone 5 - Down to -20°
Summer Hardiness: Tree will be planted in full sun
