Oakleaf hydrangea produces showy, long-lasting, cone-shaped flower panicles starting around midsummer. The 6- to 12-inch-long panicles bear many large, sterile, white florets along with small, fertile, cream-colored florets. As the large florets age they become flushed with pink, often with deeper rose speckles, then eventually turn tan. Rounding out the seasons, oakleaf hydrangea’s peeling cinnamon brown stems are beautiful when dusted with winter snow.
