Magnolia grandiflora 'TMGH'

Alta™ Southern Magnolia

Evergreen Tree

Slow growing, evergreen magnolia with a strongly upright form. Its shape and persistent foliage makes it suitable as a screen or hedge. Its narrow form is suitable for smaller gardens. This is a relatively new selection of Southern magnolia that hasn't been widely available. Since there aren't that many planted out and about, its long-term size and performance is somewhat untested in our area (the Pacific Northwest). The growers' info indicates that this very slow grower will achieve an ultimate width of 9 feet wide and 20 feet tall. Evergreen magnolia cast dense shade and are somewhat shallow-rooted, so it can be tricky to find the right planting partners for around its base.
