Another red cultivar i have been "a huntin' for". Well here it is .. It does NOT burn in sun at least up my way. It is super cold hardy. It is spectacularly red in spring and fall and holds some color through summer. This is one of my top 10 fav upright red JM's. it is suppose to get big but mine has been a slow grower. It may get big in JM preferred growing areas..but I don't see it happening here . The correct name is Masu NOT Musa ( Which is not Japanese ). Masu means "increased" in Japanese and Murasaki means purple thus intense red/ purple.
Winter Hardiness: Zone 5 - Down to -20°
Summer Hardiness: Tree will be planted in full sun
