This is a fantastic tree I have it in full sun and does fine but a bit of noon shade would help . the colors are red all season and in fall orange red. I have seen this listed as a separate plant or another name for Seigai . I think it is not Seigai but similar ... The leaf form and color do not match up . this tree is a great one for smaller spots where you want a traditional upright red JM with a very different look from the dreaded Bloodgood. It is a slow grower and super cool won't outgrow it's space.
