Hydrangea paniculata 'LIMELIGHT®' panicle hydrangea

Hydrangea

The panicle hydrangea (Hydrangea paniculata) is a deciduous shrub or small tree native to East Asia, naturally occurring in the mountain forests and valleys of China, Korea, Japan, and Russia’s Sakhalin Island. It is distinguished by its strikingly conical panicles composed of small fertile and showy sterile florets, which shift in color over the season from white through pink to wine-red, and by its high tolerance for full sun. The species was botanically described in 1829 by the German physician and botanist Philipp Franz von Siebold (1796–1866), who encountered it during his work in Japan. It reached Europe through botanical collections and expeditions of the 19th century, with the first cultivars such as ‘Grandiflora’ and ‘Floribunda’ spreading in gardens only toward the end of that century.

A milestone in the breeding of Hydrangea paniculata came with the expedition of American dendrologist Charles Sprague Sargent to Japan in 1892. He brought back seeds from which, in the following years, the cultivar ‘Praecox’ was raised—the first documented variety with early flowering. Its beauty was already praised in 1897 in the journal Garden and Forest, and when the plant became established in cultivation, Sargent himself called it in 1922 one of the most beautiful shrubs in the Arnold Arboretum. The original specimen still grows there today as a living botanical monument more than a century old.
