Japanese maple 'Twombly’s Red Sentinel'
FamilySapindaceae
Acer palmatum ‘Twombly’s Red Sentinel’, also known as 'Twombly’s Red Sentinel' Japanese maple, is a unique variety due to its naturally columnar habit, which is rare among Japanese maples. It develops deep purple, glossy foliage in spring, which remains stable in summer before blazing bright red in autumn. Its upright and narrow form makes it perfect for restricted spaces, informal hedges, or structured compositions in formal gardens. It adds verticality, color, and elegance to the landscape, while maintaining moderate and well-balanced growth. It thrives in fresh, well-drained soil, with gentle and bright exposure, sheltered from scorching winds. 'Twombly’s Red Sentinel' is an architectural maple with a strong character, while being easy to grow in Quebec conditions.
