Tiny leafed beautiful climbing cousin of petiolaris. Tiny leaves but bright white lacy blooms on this rare Korean climbing hydrangea. Leaves are even smaller than our Brookside Littleleaf hydrangea. Leaf size does grow with age but still a fantastic climber with fall color and winter interest with its corky bark. Like the wonderful cousins, this one grows in part sun/shade with cooler root locations. I think this would be a fun climber for a big container as it stays somewhat smaller than the other cousins.
