Vibrant, Color-Shifting Blue Hydrangeas for Lush, Eye-Catching Gardens
Blue Hydrangeas are a truly magical flowering shrub. Their ball-like flowers, in all shades of blue from powder blue to navy, are instantly romantic, with that signature cottage by the sea vibe. Hydrangeas have been stealing hearts for generations, thanks to their magical color-changing blooms that depend on the soil chemistry in which they grow. At TN Nursery, we've been growing hardy ornamental shrubs for over 65 years. Our plants have been used in high-profile projects at Arlington National Cemetery and The Washington Monument since 1959, and we've been the source for horticultural expertise on the Discovery and History networks. We know a thing or two, and have the authority and heritage to back it up.
The Beauty & Magic Behind Blue Hydrangeas
Blue Hydrangeas have a fascinating advantage over many other plants - their flower color can change based on the pH level in the soil. In acid soil, mophead or lacecap blossoms take on deeply saturated watercolor hues of blue. In addition to their iconic color, Blue Hydrangeas are known for their dense summer foliage, robust stems, and their rounded shape that add softness and fullness to shade or partial sun gardens. At TN Nursery, we choose varieties that have the most petal density, dependable blooming patterns, and hardiness for lasting performance.
Why Blue Hydrangeas Elevate Any Landscape
Blue Hydrangea add a touch of elegance to even the most basic of yards, creating a cottage garden feel. Blooming from early summer through fall, these flowers are a great choice for long-lasting color. They also go especially well with ferns, hosta, astilbes, iris, boxwood, and ornamental grasses. Another great feature of the Blue Hydrangea? It does well in partial shade. Their blooms and foliage can withstand the dappled sunlight of a tree canopy, as well as a shady northern exposure, or a garden bed that receives morning light. Dried Hydrangea flowers also have a rustic charm that lasts all winter long.
