Cornus racemosa Lam.
Northern swamp dogwood, gray dogwood, panicle dogwood
Gray dogwood is native to eastern North America.
Plants: Usually a thickly branched shrub 3–8′ (91–243 cm) around, but with pruning, some branches become trunks, and the plant can reach 16′ (4.9 m). It spreads by suckering, rather enthusiastically, as well as by seed.
Leaves: Medium green to gray green, opposite, 2–3½ ⨉ ¾–1¾″ (5–8.9 ⨉ 1.9–4.4 cm), narrowly elliptic or somewhat acuminate (sharp tipped), attached by thin petioles (stems) up to ¾″ (1.9 cm) long. Each leaf has prominent veins that are roughly parallel to the leaf edges. Leaf edges may be wavy. The upper leaf surface is medium to dark green, while the lower is pale green, almost white, due to the presence of tiny, flattened hairs. In the fall, leaves take on attractive red or purple coloration.
Flowers: Tiny flowers form loose or tight domes up to 2½″ (6.3 cm) around. The florets are creamy white in color, about ¼″ (6.3 mm) around, with four elliptic petals forming a four-pointed star. Four tiny stamens emerge at angles from a tiny yellow center, along with a single green-tipped style in the center. Flowers appear from May to June, but flowering is only about a week long.
Habitats: Borders, neglected areas, and embankments, thriving in wet and dry conditions and sunny or shady sites.
Fruits: Fruits are creamy white (rarely a pale blue), about ¼″ (6.3 mm) around, appearing on bright red stems in August and September.
