Growth form can be affected by regional and site conditions. Oregon white oak may be 30 to 100 feet (8-30 m) tall with a solitary trunk or up to 20 feet (5 m) tall with many trunks. In tree form, Oregon white oak's DBH is typically 24 to 40 inches (61-100 cm), although a DBH of 97 inches (250 cm) was reported in a review. Oregon white oak trunks have thick, furrowed, scaly bark. A short, crooked, and sometimes creeping form is described in rocky habitats with shallow soils. At high-elevation sites in eastern Oregon and Washington, a "shrubby" growth form is typical. A shrub form is also noted from the southernmost populations. Thilenius described "forest-form" and "savannah-form" trees in Willamette Valley. Forest-form trees were fairly tall with ascending branches near the crown and a DBH often less than 24 inches (60 cm). These trees grew in closed-canopy woodlands with nearly 1,045 trees/ha. Savannah-form trees had DBH measurements often exceeding 3 feet (1 m), massive branches, and spreading crowns. These trees grew in open woodlands with 17 trees/ha. Leaves are moderately to deeply lobed and measure up to 6 inches (15 cm) long. Generally there are 3 to 7 pinnate lobes. Margins are entire or with 2 to 3 teeth. Occasionally, trees produce a second set of summer leaves. Male flowers are catkins that are produced on the current year's growth. Female flowers are solitary or in clusters and appear in the leaf axils of new twigs. Oregon white oak produces large acorns that measure 0.8 to 1.2 inches (2-3 cm) long and mature in a single growing season. Five hundred years is the estimated Oregon white oak lifespan. Growth rates evaluated in an 80-year-old Oregon white oak-Douglas-fir stand in Oregon State's McDonald-Dunn Forest decreased by over half after the first 20 years of life. Overtopping by Douglas-fir may have affected growth." About Jonsteen's Seedlings All of our trees are seed-grown at our nursery on California's Redwood Coast, which is inspected monthly and licensed by the California Department of Agriculture. Trees can provide a natural barrier against high winds, temperatures, noise pollution and soil erosion, all while benefiting local air quality, wildlife and property values — a Jonsteen seedling will only grow in value and beauty! About Jonsteen's 100% Guarantee All of our trees are guaranteed to arrive healthy and in good condition. If your tree perishes despite your honest efforts, we will be happy to replace it with a small-sized seedling for just the cost of shipping/handling. You can learn more about our guarantee and tree replacement policy here. Size Chart Seedling Size Chart: Medium Due to the dynamic nature of actively growing trees, as well as the tremendous variation between species’ growth rates, we rely on the cubic volume of a seedling’s root mass to determine its “size” (Small / Medium / Large / XL). Within each size there is minor variance — the dimensions provided here represent the category minimum. If exact measurements are essential, please contact us about current stock.
