Dense heads of very-double flowers, white tinged green, maturing to green.
Pan Global Plants say: “Hydrangea involucrata ‘Mihara-kokonoe’ A new form fromJapan, found on theislandofOshima. This has almost indescribable, highly complex, irregularly globose flower heads composed of fertile and sterile florets. It’s mainly the sterile florets you see as they emerge on long stalks, stacking up, one after the other, opening white, then turning pale green. A vigorous plant, this can reach 1.8m. Spectacular!”
