Wow I have finally found this tree. I love mine... it is among the hardiest cultivars I have. It is sturdy fast growing holds its red well in sun and heat. Why anyone would want a stinkin' Bloodgood over this is beyond me. And why this tree is not cultivated more and therefore more readily available is also beyond me. It is simply a truly great deep red larger upright JM that everyone having the space to plant it should have. It is an old Japanese cultivars from 1688. There are two types of these one being lighter red and one being dark red. Both are keepers but likely the darker red is the correct cultivar
Winter Hardiness: Zone 5 - Down to -20°
Summer Hardiness: Tree will be planted in full sun
