Plant Profile: Chinese Hydrangea Vine (Schizophragma integrifolium)

Chinese hydrangea vine is a woody deciduous climber native to  rocky hillsides and forest edges of western and central China. It is a member of the hydrangea family, Hydrangeaceae, that also includes mock orange and  Deutzia.  Growing up to 32′  tall,  the vine will grow up trees, walls or other structures by means of aerial roots.  Growth is slow at first but becomes more vigorous with maturity.  The  broadly ovate, deep green leaves are up to 6″ long and have toothed margins and slender  pointed tips. The showy  creamy white flowerheads are up to 10″ across and resemble  those of lacecap hydrangea. The appear in early to mid summer and are composed of small flowers surrounded by  large conspicuous, white ovate bracts  up to 3.5″ long.  A good choice for shade, woodland, and wall garden. The genus name, Schizophragma, comes from the Greek words σχίζω (schizo) meanng to split and φράγκμα (phragma) meaning a fence and refers to the inner wall of the fruit capsule.  The specific epithet, integrifolium, comes from the Latin words integer meaning whole/entire, and folia, meaning leaf, and refers to the fact that the leaves are not lobed.Type: Woody deciduous vine
