Cornus amomum is a deciduous shrub growing to 5 m (16 + 1 ⁄ 2 ft) tall. The leaves are opposite, up to 10 cm (4 in) long and 7 cm ( 2 + 3 ⁄ 4 in) broad, oval with an acute apex. The flowers are produced in cymes .
Cornus obliqua, the blue-fruited dogwood, silky dogwood, or pale dogwood, is a flowering shrub of eastern North America in the dogwood family, Cornaceae. [1] [2] [3] It is sometimes considered a subspecies of Cornus amomum, which is also known as silky dogwood. [4] [5] It was first described in 1820 by Constantine Samuel Rafinesque. [6]
The leaves are 4–8 cm (1 + 1 ⁄ 2 – 3 + 1 ⁄ 4 in) long and 1–4 cm (1 ⁄ 2 – 1 + 1 ⁄ 2 in) wide, and typically have 3 or 4 pairs of lateral veins, fewer than other dogwood species. [4] The plant grows upright with a rounded habit, oppositely arranged leaves, and terminally born flowers.

Cornus rugosa is a shrub or small tree, 1–4 m (3–13 ft) tall, with yellowish-green twigs that may have red or purple blotches. Pith is white. Leaves are oppositely arranged, round orbicularly shaped with an acuminate tip, have an entire margin, and are woolly to hairless below. [4]
Like the related Cornus florida, it is very susceptible to dogwood anthracnose, a disease caused by the fungus Discula destructiva. Fungal activity is greatest from May to July, although it can be active any time conditions are moist and the plant is growing. Infected leaves become blotched and drop, and defoliation can be extreme.
