You may have noticed that PDF uses an image of a tulip throughout our website, our publications and other materials. This is because the tulip is the official symbol within the Parkinson's community.
The tulip was first recognized as a symbol for Parkinson’s in 1980. At that time, a Dutch horticulturalist named J.W.S. Van der Wereld decided to honor Dr. James Parkinson, the first person to describe Parkinson's in 1817, by naming a tulip after him. It thus became a symbol for Parkinson’s.
PDF specifically uses a yellow tulip to denote optimism and hope. The three petals are used to denote our three-pronged mission: Hope through research, education and advocacy.
