Acer palmatum ‘Twombly’s Red Sentinel’ – A Columnar Japanese Maple with Vibrant Foliage

Acer palmatum ‘Twombly’s Red Sentinel’ is a striking, columnar variety of Japanese maple that adds height and elegance to any garden. This compact tree is perfect for smaller spaces, offering a beautiful display of seasonal colour. In spring, the leaves emerge as a deep red, maturing to a rich burgundy in summer, and then turning bright red and orange in autumn, providing a stunning visual display throughout the year.

Reaching a height of 4–5 metres with a narrow spread of 1.5–2 metres, ‘Twombly’s Red Sentinel’ is ideal for narrow gardens, patios, or as a vertical focal point in mixed borders. It thrives in a sheltered position with dappled shade or partial sun, as direct sunlight may scorch its delicate leaves. It prefers moist, well-drained, slightly acidic soil. Plant in early spring or autumn to allow the roots to establish before the growing season.

Feed with a balanced, slow-release fertiliser in early spring to encourage healthy growth and vibrant colour. Applying mulch around the base helps retain moisture and keep the roots cool.

While the flowers of ‘Twombly’s Red Sentinel’ are small and not the main feature, they provide nectar for pollinators like bees, making it an excellent choice for wildlife-friendly gardens, supporting pollinator populations while adding beauty to your space.
