Great Trees Great Trees Image Image One of the most admired features of the Morris Arboretum & Gardens is its collection of large and beautiful trees. When John and Lydia Morris first purchased the property in 1887, it was virtually devoid of trees. They soon launched into an intense tree-planting program and under careful nurturing, these trees have grown into the beautiful specimens for which the Morris is well known today. Great Trees Highlights Image Dawn-redwood Metasequoia glyptostroboides A fast-growing tree with a majestic  habit, golden fall color, reddish brown  bark – fissured and exfoliating in long narrow strips – and a spectacular buttressing fluted trunk.

A male specimen is near the Edith Bogue magnolia Image Weeping European beech Fagus sylvatica f. pendula Native to Europe, planted before 1909 by the Morrises.

Small holes in trunk are made by sap sucking birds. Image Blue Atlas cedar Cedrus atlantica ‘Glauca’ The straight species is native to the Atlas Mountains of North Africa. Layered branches with blue-green needles create a picturesque landscape tree. Small finger-shaped male cones on lower branches pollinate attractive large …
