    Is this shrub is a viburnum or hydragea? Which variety? The photo was taken in Vancouver BC on June 11, 2005, so it's a June-flowering shrub in the west coast climate (zone 8).

    Thank you, Ron B. Since your reply I looked up H. macrophylla 'Madame Emile Mouillere' in Google images, finding one that shows somewhat flatter blooms that are pale pink, whereas in my picture, they are white. Are you quite sure about your identification? (The picture in Google could be mis-labelled, I suppose.)

    Lawson-Hall/Rothera, Hydrangeas (Timber Press):

    This lovely pure white hortensia flowers in July/August and then successionally until late in the season. Growing up to 180 cm (6 ft), it is very vigorous. Its large flower heads are composed of serrated or entire overlapping sepals in an overcrowded head. The florets, opening almost flat, push up against each other giving a frilly outline to the head shape. The flower heads when full of rain droop, like most mopheads, but perk up again on drying. The sepals turn blush pink or a lovely lime-green with age, and in these colours, especially the lime green, the flower heads can be dried. The flowers tend to turn brown if subjected to long drought or strong sunlight, so it prefers light shade, or a north wall, especially against a house. It is reliably identified by having unspotted stems and branches, and with red or blue eyes at the centre of the florets.
