The Nikko Blue Hydrangea (Hydrangea macrophylla) is a stunning, compact shrub that produces vibrant, round clusters of flowers. Typically, a calming, bright blue, these blossoms can shift to purple or pink depending on the soil's pH, allowing you to control their hue. Acidic soil will keep the flowers blue, neutral soil turns them purple, and alkaline soil brings out pink shades. Blooming begins in late spring, with continuous flowering throughout summer. With proper care, you can prolong the bloom season by regularly removing spent flowers. The deep green leaves offer a striking contrast to the colorful blooms, creating a beautiful visual in any garden. This hydrangea thrives in hardiness zones 6-9 and prefers partial sun, with morning sun and afternoon shade being ideal. While it can tolerate full sun, regular watering is crucial, especially during hot summer days. Ensure the soil is moist but well-draining, avoiding soggy conditions. Reaching a height and width of 4-6 ft., Nikko Blue Hydrangeas are perfect as standalone plants, foundation plantings, or in containers. They grow well in various soil types, from clay to loam, as long as it's nutrient-rich. Adding compost or fertilizer annually is recommended. Their unique ability to change color based on soil acidity makes them a versatile and enchanting addition to any garden.
