ivy's autumn leaves; scarlet-tinged ivy
Refers specifically to the red or scarlet autumn foliage of ivy (蔦). Not a general term for maple, despite the gloss 'maple'; the word literally combines 蔦 (ivy) and 紅葉 (autumn leaves/red leaves).
In autumn, the ivy's scarlet leaves covering the wall are beautiful.
The scarlet-tinged ivy is coloring the stone wall.
Compound of 蔦 (つた, ivy) and 紅葉 (もみじ, autumn leaves/red leaves). The reading もみじ for 紅葉 is the native Japanese reading.
