This is a sun-loving hydrangea and is one of the few hydrangeas that flower on the current season's growth. It can be severely pruned in late winter or spring since it blooms on new growth and not on the woody stems formed during the previous year. Showy terminal, conical to pyramidal, large panicles of creamy white flowers bloom during the summer and into fall and measure 6 to 8 inches long. The bloom changes color as autumn nears, from pink to brown.
