Sourwood (Oxydendrum arboreum) is a native tree in Maryland (Deciduous). The sections below summarize where it grows, how to recognize it, and how it supports local ecosystems.

Habitat and range

Acidic woodland slopes and edges, often leaning from understory toward light gaps.

Identification

Drooping clusters of white lily-of-the-valley-like flowers; sour-tasting leaves; brilliant red fall foliage.

Soil and moisture

Moist, acidic, well-drained; intolerant of high pH and compaction. Part sun or high canopy light limits summer leaf scorch on exposed sites.
