About plant names...

Siberian dogwood is native to eastern Russia, northeastern China, and North Korea. It is not found in the wild in North America.

Identification: Wild Siberian dogwood is about 8' (2.4 m) around, but cultivated varieties are both larger and smaller. This variety is smaller—4-6' (1.2-1.8 m) around. Deep red stems with small sparsely placed lenticels look very attractive in the winter. This variety, called both ‘Bailhalo’ and ‘Ivory Halo,’ is variegated: leaves have uneven patches of white around their edges. Leaves are 2-4½" (5-11 cm) long, and turn purple-brown in the fall. White (or yellow-white) blooms appear on growth that is at least 2-3 years old between May and June.

Common Name

Siberian Dogwood

Pagoda Dogwood

Bunchberry
Plant 4-6' (1.2-1.8 m) around. This is the tallest and most tree-like of the native dogwoods, reaching 25' (7.6 m) in height. Branches are arranged in horizontal layers with intervening gaps, leading to the common name “pagoda dogwood.” While this horizontal layering is present in most dogwoods, it is more pronounced in this one. Often only three inches high, sometimes forming nearly continuous mats on the forest floor, bunchberry rarely exceeds 8" (20 cm).
Flowers White (or yellow-white) blooms appear on growth that is at least 2-3 years old between May and June. Yellowish-white clusters of 4-petaled flowers. Four white “flower petals” are really bracts—modified leaves. They surround the real flowers, a tiny cluster of greenish flowers.
Leaves Variegated leaves have uneven patches of white around their edges. Leaves are 2-4½" (5-11 cm) long, and turn purple-brown in the fall. Deeply veined, elliptical to oval in shape, 2-5" (5-12 cm) × 1-2" (2.5-5 cm), with veins that become almost parallel with the leaf edges as they approach them. Leaf undersides are glaucous: much paler than the tops. Leaves are alternate, not opposite. Alternating pairs of oval leaves.
Stem Deep red stems with small sparsely placed lenticels are prominent in the winter. Bark on younger branches is dark reddish (or purplish) brown, turning gray on older ones.  
Fruit   In clusters, purplish-black, ¼" (8.5 mm) in diameter. A densely packed group of bright red berries above the leaves.

Common Name

Flowering Dogwood

Kousa Dogwood

Kousa Dogwood
Plant Flowering dogwood is somewhere between a large bush, at a typical 15' (4.6 m) in height, and a small tree, at up to 30' (9.1 m). It has a single trunk and rounded crown typical of a tree. Kousa dogwood is a small tree up to 20' (6.1 m) in height, rarely reaching 30' (9.1 m). More vase-shaped at first, it matures into a rounded crown. Kousa dogwood is a small tree up to 20' (6.1 m) in height, rarely reaching 30' (9.1 m). More vase-shaped at first, it matures into a rounded crown. Produces more flowers and fruit than the wild tree.
Flowers Four white “petals” (really bracts) up to 4" (10 cm) across. (The real flowers are a small green inconspicuous disc in the center.) Showy white “flowers” about 3" (7.6 cm) wide. Actually, flowers are bracts: the true flowers are an inconspicuous disc of yellow-green florets in the center. They flower from June to early July. Showy white “flowers” about 3" (7.6 cm) wide. Actually, flowers are bracts: the true flowers are an inconspicuous disc of yellow-green florets in the center. They flower from June to early July.
Leaves Opposite, 4-8" (10-20 cm) long and half as wide, with smooth edges and prominent veins, turning red to deep reddish purple in the fall. 2-4" (5-10 cm) × ¾-1" (1.9-2.5 cm), elliptic to ovate in shape, with smooth edges and leaf veins that are nearly parallel to the edges. Dark green summer leaves turn red or purple in the fall. 2-4" (5-10 cm) × ¾-1" (1.9-2.5 cm), elliptic to ovate in shape, with smooth edges and leaf veins that are nearly parallel to the edges. Dark green summer leaves turn red or purple in the fall.
Stem Trunk bark separates into square blocks or scales about 1" (2.5 cm) across as the tree ages. Trunk develops unevenly-shaped peeling scales at maturity, producing varying coloration in the trunk resembling camoflage.

Fruit Fruits are bright red, oval, ¼-½" (6.3-12 mm) long, in small tight clusters. Bumpy pink to dull red globes about ¾-1" (1.9-2.5 cm) around. Fruits reach upward on the ends of branches unless the branches bend. Bumpy pink to dull red globes about ¾-1" (1.9-2.5 cm) around.

Cornus kousa subsp. kousa ‘Lustgarten Weeping’

Cornus obliqua

Cornus sericea ‘Silver and Gold’
Common Name

Dogwood

Narrowleaf Dogwood

Silver and Gold Red Osier Dogwood
Plant This weeping variety is closely related to C. kousa ‘Elizabeth Lustgarten’, producing arching branches 12-15' (3.7-4.6 m) up, sometimes cascading to the ground, with the tree reaching a width of about 10' (3 m). The shape is more domelike and shrublike than treelike. These dogwoods are multiply branched shrubs up to 12' (3.7 m) high.  
Flowers Showy white “flowers” about 3" (7.6 cm) wide. Actually, flowers are bracts: the true flowers are an inconspicuous disc of yellow-green florets in the center. They flower from June to early July. Flowers bloom from May to June, and are yellowish-white.  
Leaves   Opposite, 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. Deep red or maroon in the fall.  
Stem   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.  
Fruit Bumpy pink to dull red globes about ¾-1" (1.9-2.5 cm) around. Green to white to light blue to deep blue. Light blue berries have a metallic sheen.
