'Mirranda' is a diminutive cultivar of  mountain hydrangea with a mature size of just around four feet.  In acidic soils the fertile and sterile flowers are a light blue while in most of the alkaline soils of the Chicago region they are pink.  As the flowers age their color changes from light blue to mauve, creamy white and finally a pale pink (in acidic soils).  The leaves are a yellowish green which provides for a nice contrast with the flowers regardless of whether they are grown in acidic or alkaline soils.
