Special Attributes


Bluebird Hydrangea is a lacecap that produces some of the most beautiful flowers we've ever seen on a Hydrangea. The hummingbird-blue center florets are surrounded by a ring of light lavender-blue flowers. Stunningly beautiful! The flowers will bloom a stronger blue in acid soils. Aluminum sulfate can be applied to increase the acidity of the soil. The leaves of Bluebird Hydrangea are large and bright green in color, and turn to an attractive red in fall.



Landscape & Garden Uses

Growing naturally 5-6 feet tall and 4-6 feet wide in a rounded mound, Bluebird Hydrangea can be grown in garden beds or containers. It is ideal for use as a specimen or accent in home foundation plantings, flowering shrub borders and perennial gardens. In larger landscape spaces it is especially dramatic in small to large groupings or in straight or staggered rows as a colorful hedge.

Spacing:  3-4' for solid hedges;  8' or more for space between plants




Cultural Preferences
Bluebird Hydrangea is very easy to grow in most any moist but well-drained soil with average fertility and full sun to part shade in northern zones and part shade (morning sun with afternoon shade or filtered sun) in southern zones. For best flowering, we suggest 4 hours of direct sun light per day. As with so many other ornamental plants, a constantly soggy or wet soil is problematic. Flower color is your choice. Acidic soils will make blue flowers while a neutral to slightly alkaline soil will make pink flowers.
