(기타)

Hydrangea quercifolia is a popular ornamental in the eastern United States, prized for its distinctive leaves, showy inflorescences, and fall color. It is introduced and naturalized in Connecticut and North Carolina, and in South Carolina is native only in the extreme western part and naturalized elsewhere. The brownish color often seen in the trichomes is imparted by tanninlike substances (W. L. Stern 1978). M. A. Dirr (2004) listed nearly 40 cultivars derived from the species.

Noteworthy Characteristics

Hydrangea quercifolia, commonly called oakleaf hydrangea, is an upright, broad-rounded, suckering* multi-stemmed, deciduous shrub that typically grows 4-6' (less frequently to 8') tall. It is native to bluffs(벼랑), moist woods, ravines (협곡) and stream banks from Georgia to Florida to Louisiana

It is noted for producing pyramidal panicles of white flowers in summer on exfoliating branches clad with large, 3-7 lobed, oak-like, dark green leaves.

 

어휘 sucker: a shoot arising below ground from the roots some distance from the main stem

 

The genus name Hydrangea comes from hydor meaning "water" and aggeion meaning "vessel", in reference to the cup-like capsular fruit.

 

Specific epithet is in reference to the leaves that look like those of Quercus (oak).

Description

Oakleaf Hydrangea is a deciduous shrub that may grow to 8 feet. It has 4- to 12-inch oakleaf-shaped leaves that are fuzzy(솜털이 보송보송한) when young. The leaves turn red or purple in the late fall. A pyramidal cluster of white blooms matures in the late spring and summer, turning purple with time. Tiny, dry seeds mature in the fall. This plant's common name is in reference to the leaves that look like those of Quercus (oak).
