I bought this tree last year for the patio. Most of the time it was a subdued plum color with a brief moment of flame red in the fall. I think I got it later in the season, after this phase of colors. I have always liked the mix of red and green in foliage.
I was having a really bad day when I took these pictures. Japanese maples are supposed to bring a feeling of serenity. I was more relaxed after a few minutes under the leaves.
