The papery, “helicopter” seeds (samaras) of Norway maples may become weedy in certain situations (Figure 2). They are considered somewhat shallowrooted, and roots may interfere with sidewalks and other landscape plants. Norway maple is probably the most commonly planted maple in the Intermountain West. Norway maple (Acer platanoides): This group of maples is well adapted to the Intermountain West and is typically tolerant of alkaline soil and arid climate. For specific cultivar recommendations, see Table 1.įigure 2. ![]() Understanding these species’ general characteristics will help you determine if a cultivar may be a good fit for your landscape. There are several parent species from which maple hybrids and cultivars are derived. When selecting a tree for your landscape, choose a cultivar that is well adapted to your soil and conditions. If left untreated, branch death or even tree death can occur. This nutrient deficiency causes yellowing leaves (chlorosis) with green veins, and in extreme conditions, can cause death of leaf edges. A common problem associated with maples in the Intermountain West is iron chlorosis (Figure 1). In Utah, high pH is common and may cause some micronutrients, particularly iron, to be less available, making it difficult for certain trees to take up needed nutrients. Soil chemistry and characteristics are important considerations when choosing maple trees. There are many factors to consider when selecting a maple for your landscape, including tree size, leaf color, fall foliage color, leaf shape, and disease resistance.

Tree shape can vary greatly, ranging from upright, columnar, rounded, pyramidal to spreading. Trees vary in size and shape, from small, almost prostrate forms like certain Japanese maples (Acer palmatum) and shrubby bigtooth maples (Acer grandidentatum) to large and stately shade trees like the Norway maple (Acer platanoides). There are over one hundred species, each with numerous cultivars (cultivated varieties) that are native to both North America and much of Northern Europe. These 25 Japanese maples are all great options, offering foliage ranging from red and yellow to green also featuring different growth habits and tree heights.Maple trees (Acer sp.) are a common fixture and beautiful addition to Utah landscapes. While there are many ways to select a Japanese maple, leaf color is why most people plant this tree. Many popular cultivars produce the familiar red foliage, such as one of the most popular Japanese trees, 'Bloodgood.' But others provide brilliant green or gold tones-and even bicolor leaves. ![]() In zones 7–8, they can benefit from planting in partial shade or dappled sunlight to protect the leaves from leaf scorch in the summer heat. Japanese maples should be planted in full to partial sun and in well-drained soil. They are suitable for USDA hardiness zones 5a–8b, though a few can brave zone 4 if planted in protected locations. The many different kinds of Japanese maples include Acer palmatum, Acer japonicum, and Acer pictum they are all part of the Sapindaceae (soapberry) family. ‘Sango Kaku’ is prized as one of the prettiest Japanese maple trees for its changing foliage but also bright coral bark, which gives this tree its striking contrast all year round. The foliage offers striking color throughout the growing season, becoming even more beautiful with the fall color change. ![]() Several dwarf varieties stay small and can be trained as bonsai.Īlthough the tree blooms in spring, it's the palmate leaves with five-, seven-, or nine-toothed finger-like leaves that offer the real appeal. With over a thousand varieties, it is a smallish species, with mature heights of 4–30 feet, depending on the cultivar. Japanese maple tree varieties are prized for their delicate and colorful foliage throughout the growing season and autumn. The Spruce Home Improvement Review Board.
