Origin & Breeding History: 'Whip Pur' originated from a cross made in September 2000 at Gilroy, California. The female parent was 00-382-4, a proprietary line with purple flowers. The male parent was 00-381-2, a proprietary line with scarlet flowers. The resulting F1 seed was sown in a greenhouse in December 2000. In March 2001, a single plant was selected by the breeder from the F1 progeny, based on flower colour, form and plant habit.

Tests & Trials: Tests and trials for 'Whip Pur' were conducted in a polyhouse during the summer of 2004, in St. Thomas, Ontario. The trial included a total of 15 plants of each variety. All plants were grown from rooted cuttings, planted into 15cm pots on April 21, 2004. Observations and measurements were taken from 10 plants of each variety on June 1, 2004. All colour measurements were made using the RHS Colour Chart 2001.
