Gutter, an employee of Syngenta Seeds B.V. in Enkhuizen, The Netherlands. 'Audelpur' was selected in March 1999 based on its early flowering and compact plant growth habit. Asexual reproduction by cuttings was first conducted in August 1999 in Enkhuizen, The Netherlands.

Tests & Trials: Trials for 'Audelpur' were conducted during the winter of 2008 at BioFlora Inc. in St. Thomas, Ontario. There were 15 plants of each variety. All plants were grown from rooted cuttings and transplanted into 16 cm pots on May 8, 2007. Observations and measurements were taken from 10 plants or parts of plants of each variety on February 29, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
