Hydrangea macrophylla ‘Goliath’ is a vigorous, free-flowering shrub. Probably the largest mophead flowers in our collection. The name refers to the size of the flowerheads, not the overall plant size. The size of the mature shrub is 1.5m,, the usual size for the H. macrophylla species, but the flowerhead is 240mm across, very large! Fortunately, it has strong stems which support the substantial flowers.
This variety has been around since 1923 and still features strongly in hydrangea collectors’ gardens.
Inflorescence: Mophead, 240mm across, soft pink or purple-blue. The highly serrated sepals give this plant a very frilly appearance when in full bloom. We can strongly recommend this hydrangea for any collection.
