Japanese Mountain Hydrangea

Hydrangea serrata ‘Blue Deckle’
Hydrangea serrata ‘Blue Deckle’

Hydrangea

Climbing Hydrangea

The name Hydrangea, means “water vessel,” given for its cup-shaped seed capsules. A genus of diverse forms, Hydrangeas are commonly found throughout Asia, from the Hima­layas to Taiwan and Japan, with the exception of two species, Hydrangea arborescens and Hydrangea quercifolia, which are native to North America. Easily cultivated, this shrub’s lush deciduous leaves are best suited to loose, moist soil in the shade of tall trees or on the north side of the house.

<i>Hydrangea serrata</i> ‘Blue Deckle’

A sterling, highly sought after progeny of renown horticulturist and Hydrangea expert Michael Haworth-Booth’s breeding efforts, this low growing Hydrangea lulls us with cool, light blue lacecaps. The central fertile flowers are encompassed and sometimes hidden by prominent serrated sepals that later transmute sea-green and lilac-purple in sumptuous, glimmering shades. Compact and closely set, red-dashed green stems shape its attractive dwarf frame, while launching a fiery autumnal pageant of purple-rimmed, cardinal-colored leaves soon after the prolific blooms begin to fade.

Blooms July–September.

Size: 4' 0" high x 4' 0" wide.

Hardy to zone 6.
