Ideal on its own or as an accent in a shrub border of by house foundations, plus it can be planted in hedge formation. Will grow best in eastern and central Kansas.

Interesting Notes about Bigleaf Hydrangea:

In high pH soils, flowers will be pink rather than blue. This is tied to the availability of aluminum in the soil (less availalbe in high pH soil - almost all of Kansas), which is needed to develop the blue pigment. Treatments to change flower color must be applied well before flower development.
