These have a ring of large petals (sepals) around the outside of each floral cluster, with smaller flowers on the inside. The colour varies with soil acidity as with Ball head hydranges.

Acid Soils will produce blue flowers (you may need to add Hydrangea Blueing tonic – Aluminium sulphate – to maintain the colour in Canberra). Alkaline soils will produce pink, purple and red-coloured blooms. White flowers will always be white. All flowers mature and age to green. In winter prune each stem back to two plump buds. These Hydrangeas prefer morning sun to full shade and well composted, moist soil.
