The female parent was the Hydrangea paniculata variety 'Pink Diamond' and the male parent was an unnamed variety. The resultant seed from the cross was treated with colchicine and the progeny from the treated seed were grown. The new variety was selected based on its attractive flowers, plant habit and resistance to disease. The new variety was first propagated by softwood cuttings in 2002, in Melle, Belgium.

Tests & Trials: The tests and trials for 'DVPPinky' were conducted in an outdoor trial at BioFlora in St. Thomas, Ontario in the summer of 2006. The trials included 10 plants of each variety. All plants were grown from 5 inch liners, planted into 2 gallon containers in May 2004 and transplanted into 3 gallon containers on July 2, 2004. Observations and measurements were taken from 10 plants of each variety. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour chart.
