Varieties used for comparison: 'Evipo003' (Ice Blue) and 'Elsa Spath'
Summary: 'Evipo017' differs from the reference varieties 'Evipo003' and 'Elsa Spath' in flower colour. The main colour of the upper side of the sepals of 'Evipo017' is lighter blue violet than 'Elsa Spath' and darker than 'Evipo003'. 'Evipo017' sepals have only one colour on the upper side, whereas 'Elsa Spath' has two colours on the upper side of the sepals. The undulation of the sepal margins is strong for 'Evipo017', while it is weak for 'Evipo003' and very weak for 'Elsa Spath'. 'Evipo017' has cream coloured anthers, compared with 'Elsa Spath' which has reddish purple anthers.

BASAL LEAFLET: ovate, acute to cuspidate apex, acute to obtuse base, entire margin, no lobing, medium green on upper side, no variegation, absent to weak rugosity
FLOWERS: solitary and clustered arrangement, upwards orientation, single flower type, rotate shape, flat to concave in cross section, weak fragrance
SEPALS: six to eight, overlapping, ovate, flat to concave in cross section, flat to moderately reflexed in longitudinal section, cuspidate apex, type one base, strong undulation on margin, no twisting along longitudinal axis
SEPAL UPPER SIDE: one colour, blue violet, even distribution,
SEPAL LOWER SIDE: two colours, blue violet main colour, white central bar secondary colour

Origin & Breeding History: 'Evipo017' 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 light violet flowers, good repeat flowering, compact habit, suitability for containers and good flowering as a young plant.
Tests & Trials: Trials for 'Evipo017' 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.
