A variegated cultivar:  Heronswood say: “A sport from Hydrangea macrophylla var. normalis ‘Tricolor’ shared with us by Marco Stufano, with silvery margined and blotched foliage and large, striking lace caps of blue centers surrounded by white sepals. A very pretty Hydrangea form for which we thank Marco and the fine folks at Wave Hill. 4.5 ft.”
