Swamp Chestnut Oak is a medium-sized native deciduous tree with a tight narrow rounded crown and flaky ridged bark. The large shiny green foliage has wavy margins with a fuzzy grey underside and turns dark red in fall. The inconspicuous spring flowers are followed by edible acorns that ripen in early fal. Best grown in full sun and loamy moist well-drained acidic soils. Tolerates wet soils and occasional flooding. Swamp Chestnut Oak is popular with wildlife once it starts producing acorns, and has one of the few acorns that can be eaten directly without boiling.
