A slow-growing, deciduous hybrid tree with peeling creamy-white bark on the trunk and branches, and ovate leaves which emerge glossy-green in the spring and change to shades of yellow in the autumn. Suitable for smaller gardens, this variety has a narrower head than other varieties and in ideal conditions may reach a maximum height of around 6m. Will tolerate most types of soil, even wet, but best on acid soils to achieve the maximum height
