About plant names...

Narrowleaf dogwood is native to eastern and central North America.

Identification: 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 are opposite, on stems up to ½" (1.5 cm) long. Leaves are deeply veined on the back, up to 4" (10 cm) × 1¼" (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 bloom from May to June, and are yellowish-white. 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—it has a sheen that actually looks metallic.
