Sorbus decora - Showy Mountain-Ash - Dogberry
Sorbus decora, commonly known as the Showy Mountain-ash also known as Dogberry. It is native to northeastern North America. It occurs throughout the Great Lakes-St. Lawrence Mixedwood forest region, the New England-Acadian forest region, and the eastern Canadian boreal forests. It is a deciduous shrub or very small tree and the bark of an adult plant is thin and smooth
Showy Mountain-ash is very similar to the closely related American Mountain-ash. It grows up to 10 m (33 ft) in height and spread up to 8 m (26 ft). Like the American Mountain-ash (Sorbus americana), the Showy Mountain-ash has pinnately compound leaves and often large clusters of flowers and fruits. However, a useful distinguishing feature of this species is its shiny, sticky buds. The leaves are green above, paler beneath, 10–20 cm long and 6-12 board. The leaf blade is compound (made up of two or more discrete leaflets). There is one leaf per node along the stem, and the edge of the leaf blade has teeth. The color of the leaves change to red in autumn. It blooms white flowers in late spring to early summer. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects. The fruits color are red or orange. It is a pome 7–8 mm diameter, maturing in late autumn. 
It is often cultivated as an ornamental plant for its cold-hardiness, its attractive flowers, and its large clusters of small red berry-like pomes. The fruits are an important source of food for wildlife, particularly birds in the winter and early spring.

It blooms white flowers in late spring to early summer. Inflorescence a large, pubescent, flat-topped panicle, with at least 70 flowers, with the 5 lobes triangular; petals 5, oval, 5-6 mm. Fruit sub-globose, fleshy, orange to scarlet, glossy, about 1 cm broad. Fruit - raw, cooked in pies, preserves etc. or dried for later use. A bitter flavor.

Sorbus sargentiana commonly known as Sargent's Rowan. It is native to southwestern Sichuan and northern Yunnan in China.
It is a small to medium-sized deciduous tree. It is growing to 6–16 m (20–52 ft) in height. The trunk of S. sargentiana grows up to 50 cm (20 in) in diameter, and a rounded crown. The bark is dark grey, and the shoots very stout, with large (1–2 cm), dark red, sticky resinous winter buds. The leaves are the largest of any rowan, dark green with impressed veining above, glaucous beneath, 20–35 cm (8–14 in) long and 15–20 cm (6–8 in) broad, with persistent 1 cm broad stipules. The pinnate leaves conisist of 9–11 oblong-lanceolate leaflets 5–14 cm (2–6 in) cm long and 3.5–5 cm (1–2 in) broad, with an acute apex, serrated margins. The basal leaflets are slightly smaller than the apical leaflets. They change to a rich orange-pink to purple or dark red in mid-autumn. It blooms in late spring to early summer. The flowers are 5–7 mm in diameter, with five white petals and 20 yellowish-white stamens; they are produced 200–500 together in very large corymbs 12–25 cm (5–10 in) in diameter. The fruit is a pome 5–8 mm diameter, bright orange-red to red, maturing in early autumn; it is juicy, and readily eaten as soon as it is ripe by thrushes, which disperse the seeds. 
It is grown as an ornamental tree for its bold foliage, huge clusters of fruit, and bright autumn color. It is also cultivate in USA and Europe as an ornamental tree, in the park and garden.
