White Wave is a hefty white lacecap hydrangea that produces waves and waves of flowers - it's free flowering. Hefty and heavy and super stylish . . . like a chic friend who wears white garments all summer long. A natty dresser, is the term.
Oh, and look at the leaf in the picture. The dark green leaves are a cut above, literally, they have more serrations than most Hydrangea macrophylla (Madame Emile Mouillere is also a cut above this way).
The flowers are typically described as pearly white, which I'm interpreting literally too. My pearl (yes, my ONE pearl) is not pure white, it has a faint pink tint to it in certain light. The fertile florets of White Wave bigleaf hydrangea are white and mature pinkish white in alkaline soils and bluish white in acidic soils. Likewise, the fertile flowers are either pink or blue - the fertile flowers being more vividly colored than the sepals.
The flowers start out light green, open in the pearly ways described, then again age to light green.
White Wave is not one of the compact or smaller hydrangeas. It's vigorous and stems are strong - the leaf picture shows how the current year's stems are slightly mottled. This will easily become a 5-6' tall bush.

To Make It Thrive
Give White Wave rich soil plus consistent moisture in a soil that drains. It may require extra watering, but avoid standing water. Grow it in full shade or afternoon shade in the deep south (zones 8 and 9), not only for the foliage, but so the flowers don't get sun scald. Full sun is okay farther north. For flowering in cold climates, situate it in a warm sheltered location. During the ups and downs of spring temps here in Zone 8a - we cover to protect flower buds.
