Cornus obliqua Raf.

Narrowleaf dogwood, silky dogwood, swamp dogwood

Narrowleaf dogwood is native to eastern and central North America.

Plants: These dogwoods are multiply branched shrubs up to 12′ (3.7 m) high. Branch bark is highly variable in color: gray, brown, reddish brown, red, or yellow-brown. Young twigs have fine hairs; mature branches have vertical lenticels.

Leaves: opposite, on stems up to ½″ (1.5 cm) long. Leaves are deeply veined on the back, up to 4 ⨉ 1¼″ (10 ⨉ 3.5 cm) in size, oval with pointed tips, somewhat narrower than other dogwood leaves. They turn deep red or maroon in the fall.

Flowers: Yellowish-white, blooming in May to June.

Fruits: The berries are, well, if you ask me, awesome. First, they’re colorful: they go from green to white to light blue to deep blue. It is the light blue phase that I like best—they have a sheen that actually looks metallic.

Habitats: Moist, rich, slightly acidic soils such as swamps.
