Acorns that fall with their caps on are not good to plant.
Swamp white oak is uncommon, but can be found in moist bottomlands in southwestern Ontario, in the Niagara Region and an isolated stand at the eastern edge of Ontario-Quebec.
Swamp white oak has shiny dark green leaves up to 17 cm long, with fuzzy pale green undersides. In the white oak family, the leaves are rounded lobes, not pointed tips. The acorns have a long stalk and the scales on the acorn cap are recurved and pointed.
As the name suggests, this species is closely related to our native white oak, except its preference for wetter and heavier soils. It does not like drought.
Size: Up to 22 m tall
Moisture: Prefers moist soils, tolerates seasonal flooding
Shade: Will grow in part shade or full sun
Soil: Prefers rich, slightly acidic soils
Planting Tip: It is best to transplant field-grown and bare root oaks in spring before they leaf out, but smaller container-grown trees can be moved with careful attention to watering later in the spring or fall. More tips...
