Raywood Ash is a deciduous ornamental Ash capable of reaching more than 80 feet in height. Mature landscape size is consistently 40 to 50 feet tall with a 25 foot spread in a landscape. You can rely on Raywood Ash to provide a full, rounded canopy, with fine textured foliage. Young trees are somewhat upright or oval, making them suited in suburban areas and large landscapes.
The lustrous, dark green leaflets make it well-suited for use as a large lawn specimen or shade tree. As an ornamental tree, the foliage has a nice sway as the wind blows and provides light shade in the summer. The leaves turn various shades of red to purple before falling in autumn.
Performance is best in full sun, Raywood is moderately drought-tolerant once established. Although trees can tolerate wet sites, they will perform much better in well-drained conditions and grow stronger limbs. As with all ornamental and shade trees, deep watering is the best practice to grow a robust and resilient root system while the tree is getting established in the landscape. Surface roots can be a problem on wet sites and on clay soil but they otherwise grow in a range of soil from sand to clay.
