Saw-leaf Zelkova (Zelkova serrata), also called Japanese Elm, is a deciduous tree from Asia that is among the trees most commonly planted by the City of Woodland. It usually grows to about 100 feet tall and has a lifespan of over 1,000 years. It typically has a short single trunk that branches out in a vase shape and forms a broad, round-topped head. It is fast-growing, especially when young. It prefers full sun or partial shade and good drainage.  It is highly resistant to Dutch elm disease. Male and female flowers are borne on the same tree, with the female flowers located closer to the tips of the branches. Saw-leaf Zelkova is ranked 10 out of 10 on the Ogren Plant Allergy Scale, indicating the most severe allergenicity. If you have hay fever from about December through May and there is a Saw-leaf Zelkova planted near your home—which there almost certainly is, if you live in Woodland—then that Saw-leaf Zelkova should be considered a prime suspect for inflicting all that misery and long-term lung damage on you. The City of Woodland has planted Saw-leaf Zelkova at Beamer ParkChristiansen Park, City HallDave Douglass Park, Dick Klenhard Ballfield ComplexEverman Park, Grace Hiddleson Park, Jack Slaven ParkJeff Roddy Memorial Park, John Ferns Park, Ralph Harris Park, Spring Lake ParkWoodland City CemeteryWoodland West Park, and Woodside Park.
