Acer palmatum 'Twombly's Red Sentinel' is a dense, slow-growing, deciduous shrub or small tree with narrowly upright columnar growth habit. Over time, it becomes more spreading and bushy. Its small, palmate, 5-lobed leaves emerge bright red in spring, become purple-red or burgundy in summer, and scarlet red in autumn. In winter, bark and branches are blood red, adding to its ornamental value. Red Sentinel Japanese maple loves rich, moist, but well-drained soils, though it can grow in any soil type. The foliage has best colour in partial shade, but it is tolerant to full sun. Needs to be watered regularly and sheltered from harsh winds. Lack of soil moisture and excessive exposure can cause leaf scorch. Acer palmatum 'Twombly's Red Sentinel', with its narrow upright habit and refined foliage, is a perfect option for small gardens and great as specimen plant. It is suitable for urban and cottage gardens, and for growing in pots and containers.

About Us

During this time, we have developed a large stock of trees, mature evergreen shrubs, conifers, Japanese maples, cedars and olives. What sets us apart from a generic garden center is solid unwavering focus on trees and some bigger shrubs. You will find thousands of trees, hundreds of varieties and lots of experts who are working on the nursery and more than willing to help you to choose a plant for you.

What you will not find is hot tubs, garden furniture and plastic garden gnomes. In a nutshell, trees is what we know and trees is what we do, and only trees (and some shrubs to go with the trees).
