There are two colours on the lower side of the sepals of 'Evipo003', while the sepals of 'Elsa Spath' have three colours on the lower side. The margins of the sepals of 'Evipo003' are weakly undulating, compared with the margins of the sepals of 'Evipo017' which have strong undulation.

Origin & Breeding History: 'Evipo003' originated from a controlled crossing between two unnamed seedlings in Guernsey, UK, during the spring of 1995. The resulting seeds were germinated in January of 1996 and the seedlings were evaluated under controlled conditions during the following summer. After the initial evaluation of the seedlings, the new variety was selected and assigned a breeding code, and it was reproduced by asexual propagation from vegetative cuttings. The breeding objective was to create a new variety with white flowers with a slight violet blue tone, with flowers developing on the lower portion of the plant, lower than the previous season's height.

Tests & Trials: Trials for 'Evipo003' were conducted during the spring and summer of 2008 in St. Thomas, Ontario. The trials included 6 plants of each variety. Bare-rooted plants were planted in 4.5 inch pots on December 10, 2006 and grown in a polyhouse. All plants were transplanted in the field on May 29, 2007, spaced 2 feet apart and trained to grow along a trellis. Observations and measurements were taken from 10 plant parts of each variety on June 27, 2008. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
