BLOODGOOD LONDON PLANE TREE (Platanus x acerifolia ' Bloodgood'), c.s. - 40'+ <br /> A popular street tree throughout much of the temperate zone, this long - <br /> lived, sturdy species is relatively uncommon in Eugene. It does best on <br /> deeper soils, but it thrives on the heavier soils of the clay neighbor- <br /> hoods, too. Its very light - colored bark, its curious seed clusters, and <br /> its large, maple -like leaves make it an interesting addition to our <br /> urban forest. The 'Bloodgood' cultivar is resistant to anthracnose, a <br /> fungal disease that grossly disfigures other plane trees in the Wil- <br /> lamette Valley. (SW corner of Polk and W 13th, by the Faith Center <br /> parking lot; 15 -yr -old trees) <br /> PIN OAK (Quercus palustris), crown spread - 40'+ <br /> Native to swamps of eastern North America, this species does admirably <br /> in our poorly drained clay neighborhoods. Young trees have a very <br /> symmetrical, graceful habit, with slender side branches swooping down <br /> from a single trunk; they may retain some of their leaves through the <br /> winter (unless selected in the nursery for fall leaf- drop). Older trees <br /> have a more upright habit, with multiple large branches ascending from <br /> the main trunk; they all lose all of their leaves in fall. The half - <br /> inch long acorns are quite small for an oak. (Oak St btw 15th and 16th; <br /> 25 -yr -old trees) <br /> BLACK LOCUST (Robinia pseudoacacia), crown spread - 30' <br /> A very hardy tree from eastern North America, this species grows well on <br /> all of the different soils found in Eugene. In May, it produces showy, <br /> wisteria -like chains of fragrant, white flowers. Its relatively thin <br /> canopy, which casts a very light shade, and its small leaflets make for <br /> an easy job of leaf- raking in fall! The dark, deeply furrowed bark and <br /> picturesque growth habit is characteristic of older trees. (NW corner <br /> of Alder and E 27th; several 20 -yr -old trees, with two new ones planted <br /> on E side of Alder St) <br /> SILVER LINDEN (Tilia tomentosa), crown spread - 30' <br /> Lindens are beloved throughout the temperate zone for their fragrant <br /> flowers in early summer, and their yellow foliage in fall. Their habit <br /> (i.e., the direction their branches grow) makes them ideal streetside <br /> trees, as their main branches /trunks are upright, while their smaller <br /> side - branches curve back down, well out of the way of traffic. This is <br /> the best - adapted linden species for our winter - wet /summer -dry climate, <br /> but it does not do well on clay soils. Its leaves are dark green on top <br /> and silvery -gray beneath.

A native of swampy areas of eastern <br /> North America, it is admirably suited to the heavy clay soils in some <br /> neighborhoods. The relatively small leaves have silvery -white under- <br /> 3 <br />
