sides; fall color ranges from yellow to scarlet, depending on the <br /> individual or cultivar selected. Red maples have unfortunately been <br /> much over - planted in Eugene, so homeowners are encouraged to choose <br /> instead from a broad variety of other trees equally well- suited to our <br /> soils and climate. (1165 E 21st, 10 -yr -old trees; SW corner of Alder <br /> and 25th, 2 new trees) <br /> RED ALDER (Alnus rubra), crown spread - 30'- 40'+ <br /> A common tree in western Oregon, especially along watercourses, this <br /> hardy native has too long been ignored in cultivation. Young trees <br /> quickly become established and grow rapidly on all of our soils. The <br /> species requires supplemental water during the establishment period, but <br /> older trees are fairly tolerant of our summer drought. Leaves appear <br /> early in spring, and remain late into fall. And the alder's tiny seeds <br /> are relished in winter by chickadees, siskins, and finches. (a 4 -yr- <br /> old at 1425 Washington, in front yard) <br /> EUROPEAN HORNBEAM (Carpinus betulus), crown spread - 30' <br /> A common tree in the understory of European forests, this species is <br /> adaptable to a wide variety of soils and other growing conditions. The <br /> "type" or wild species develops a lovely, broad - spreading canopy early <br /> on. The columnar cultivar, however, has a very narrow form when young, <br /> then acquires a teardrop shape in middle age, and finally in mature <br /> trees (over 75 years of age) becomes fairly rounded. The charming <br /> foliage turns yellow in fall, and young trees may retain some of their <br /> leaves throughout the winter. (SE corner of University and E 15th, in <br /> EMU courtyard, 15 -yr -old trees; Willamette St, btw 7th and 8th, 25 -yr- <br /> old trees of the columnar cultivar) <br /> FLAME ASH (Fraxinus oxycarpa 'Flame'), crown spread - 20' <br /> This cultivar of Mediterranean ash does superbly in our climate, and is <br /> especially suited to the heavy clay soils of some neighborhoods. Its <br /> symmetrical growth habit, delicate leaflets, and stunning fall colors <br /> have made it a popular street tree throughout the Northwest. Like red <br /> maple, however, we need to avoid overplanting this species. (NW corner <br /> of Patterson and E 19th; 10 -yr -old trees) <br /> GREEN ASH (Fraxinus pennsylvanica), crown spread - 30'- 40'+ <br /> One of the hardiest of the hardy, this tree can be grown from the <br /> prairie provinces of Canada to both the east and west coasts of the <br /> U.S., and it does well on clay soils, too. The first tree here to turn <br /> color in fall, its rich green foliage begins transforming to bright <br /> yellow already by the end of September. Unlike wild green ashes, most <br /> cultivars available in the nursery trade are seedless and develop <br /> symmetrical canopies. (west side of 600 -block of Monroe, 15 -yr -olds) <br /> LACEBARK ELM (Ulmus parvifolia), crown spread - 30' <br /> This lovely, fast - growing tree from eastern Asia is quite rare in our <br /> community, yet it grows well on all of our soils. It is especially <br /> well- adapted to the clay neighborhoods. The small, toothed leaves cast <br /> a fairly light shade and turn yellowish in fall. Flowers and seeds are <br /> both produced in fall, unlike other elms. As the tree matures, it <br /> 4 <br />
