Hydrangea macrophylla 'PIIHM-II'
BloomStruck, is another breeding breakthrough. After 50 days below 0 degrees F, and a low of -28 degrees F, BloomStruck flowered heavily the following spring on old growth and put out loads of blooms on new growth. In addition to being cold tolerant, BloomStruck's glossy dark green leaves are more heat resistant, which prevents wilting in mid-day heat. This reblooming mophead has rounded flowers averaging, 3.5-5" across in intense rose-pink, violet or blue, depending on pH levels. Flower heads are help upright on striking ruby red stems, adding to this plant's retail presence.
