Hydrangea macrophylla ‘Mariesii Perfecta’
blue wave lacecap hydrangea
An outstanding seedling of the well known and popular cultivar 'Mariesii' this old French selection is truly the perfect and classic lacecap hydrangea. A profusion of flowers are well-spaced over the shrub starting in early summer. Each flower is pale lilac-blue to light pink depending on the acidity of the soil with the small central fertile flowers of a deeper corresponding color. It is an excellent variety for drying, retaining color well and often drying to a silvery blue. The light, bright green foliage frames the flowers showing them to their best advantage. The bold foliage is a great textural contrast to rhododendrons and azaleas. The lovely pale hues look great with variegated foliage or silver and gray leaves. Shade loving perennials like hostas and epimedium make a great foil around this proven summer bloomer. Hydrangea macrophylla 'Mariesii Perfecta' is often sold under the invalid name of 'Blue Wave'.

Culture NotesThis hydrangea grows best in light to open shade. A location protected from hot sun will keep the foliage and flowers from prematurely fading or scorching. A rich moist to well-drained soil produces the best growth and flowering. Hydrangeas are not drought tolerant and will grow and flower more prolifically with regular summer watering. The typically acidic soils of the Pacific Northwest will cause the variable flowers to bloom in pale purple and blue tones. For light pink flowers, add lime to raise the pH and sweeten the soil. Have a soil test done to determine the amount of lime. Changing the color can often take a few years to accomplish with more than one application of lime. Remove a few old twiggy branches to the ground yearly or prune lightly to improve the overall shape. Heavy pruning can ruin the flowering for the following year. Consult an experienced pruner or take local classes before attempting substantial pruning.
