Acer palmatum 'Twombly's Red Sentinel'
Common Name: Twombly's Red Sentinel Japanese Maple
Acer palmatum ‘Twombly’s Red Sentinel’ is a distinctive Japanese maple valued for its narrow, upright habit and rich red foliage, making it an excellent choice where vertical emphasis is desired. Spring growth emerges deep crimson-red, holding a dark burgundy to purple-red tone through summer when grown in partial shade. Leaves are medium-sized with classic palmate lobes, giving the tree a refined yet bold appearance. In fall, ‘Twombly’s Red Sentinel’ turns brilliant scarlet to crimson, providing a vivid and reliable autumn display. The naturally columnar form sets it apart from broader red cultivars. This cultivar performs best in partial shade and well-drained, evenly moist soil, and is especially useful in tighter garden spaces without sacrificing color impact.
