A very hardy reliable bright red open JM that does okay in sun but can take the cold also . it doesn't much like wet areas and tends to be a slow grower but is a nice medium to small red upright . I don't see it getting anywhere near 12' here in many many years but in friendlier confines it may get even bigger.
Winter Hardiness: Zone 5 - Down to -20°
Summer Hardiness: Tree will be planted in partial shade
