Outstanding Qualities

The best in pure white lacecap hydrangeas is 'Larnath White'. This reliable cultivar produces abundant flowers with a particularly lacey appearance. Virginal white sterile-florets loosely corral the tiny, baby-blue fertile flowers within a delicate disk. The display begins in early summer and lasts until autumn. The entire effect is enhanced by the light green foliage, giving a luminescent effect to the lightly shaded garden. Plant with dark evergreen foliage, such as rhododendrons and azaleas to heighten the experience. Shade loving perennials like hostas and epimedium make a great foil around this prized summer bloomer.

Culture Notes
This 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 with purple and blue tones. For 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.
