Acer palmatum ‘Twombly’s Red Sentinel’ (Japanese Maple)

Perfect for small gardens, Acer palmatum ‘Twombly’s Red Sentinel’ (Japanese Maple) is a dense, upright, columnar shrub or small tree with changing foliage, season after season. Emerging bright red in spring, the delicate foliage of palmate, 5-7 slender tipped lobed leaves gradually changes to purple-red or reddish green as the season progresses before turning brilliant red with orange hues in the fall. The unique narrow shape of this Japanese Maple selection makes it perfect in situations where space is limited.

• Grows up to 10-15 ft. tall (300-450 cm) and 7-8 ft. wide (210-240 cm).
• A full sun or part shade lover, this plant is easily grown in moist, organically rich, slightly acidic, well-drained soils. Mulch helps retain soil moisture and keep roots cool. Best leaf color in partial shade, although full sun can be tolerated. A lack of soil moisture or excessive exposure can cause leaf scorch.
• Perfect as a specimen plant in cottage gardens, city gardens, or Japanese gardens and containers.
• Low maintenance, this plant needs little pruning. If pruning is necessary, prune during the dormant season and avoid pruning in spring when the sap is running. Fertilize in spring before the leaves emerge.
• It may be affected by horse chestnut scale, aphids, and verticillium wilt.
• Propagate by grafting or softwood cuttings.
• Acer palmatum is native to Japan, Korea, China, eastern Mongolia, and southeast Russia.
