Variety Description

Varieties used for comparison: 'Seiboldii' and 'Evirida' (Pistachio)

Summary: 'Evipo006' has smaller diameter flowers with a greater number of petaloid staminodes than 'Evirida'. 'Evipo006' has petaloid staminodes from the time its flowers open whereas 'Evirida' only develops petaloid staminodes with age. The petaloid staminodes of 'Evipo006' are purple whereas those of 'Evirida' are greenish white. 'Evipo006' has a larger overall diameter of the petaloid staminodes than 'Seiboldii' and 'Evirida'. 'Evipo006' has no stamens whereas 'Evirida' has stamens with a white filament and purple anther.


PLANT: climbing type, weak vigour
YOUNG SHOOT: moderately dense pubescence

LEAF: simple, ternate and biternate types
LEAF BLADE: ovate shape, ranging between acute and cuspidate apices, obtuse to oblique base, entire margin, two lobes per leaf blade, deep sinus between lobes, upper side is light green with reddish brown at margins, no variegation, absent or weak rugosity of upper surface

FLOWER: solitary arrangement, outward facing attitude, single anemone type, rotate shape, cross-section in lateral view is flat becoming convex with age, absent or very weak fragrance
SEPAL: only six per flower, overlapping arrangement, ovate shape, concave to flat in cross-section, curvature in longitudinal-section is absent to moderately reflexed becoming recurved with age, acute apex with mucronate tip, type two base, one even colour on upper side, gray (RHS 157C-D) to white on upper side, white with light green (RHS 145A-B) midrib on lower side, weak undulation of margin, no twisting along longitudinal axis
PETALOID STAMINODE: many, main colour on upper side is purple, inner petaloid staminodes are yellow green (RHS 150C) with violet (RHS 77A) tips, outer petaloid staminodes are white (RHS 155C) with dark violet (RHS 83B) along margins

Origin & Breeding History: 'Evipo006' originated from a cross made in the spring/summer of 1995 between the variety 'Evipure' and an unnamed seedling. The resulting seed was planted in December 1995 and in the spring of 1996, the seedlings were selected at Domarie Vineries Les Sauvagees, in St. Sampsons, Guernsey, Channel Islands, United Kingdom. The objective of this hybridization was to create a new and distinct variety for commercial glasshouse and nursery culture with a very long flowering season, evergreen foliage when protected from frost, good flower longevity, continuous flowering from May to October and attractive, domed flowers with a purple center.

Tests & Trials: Trials for 'Evipo006' were conducted in a polyhouse during the winter and spring of 2009 at BioFlora Inc. in St. Thomas, Ontario. It included 10 plants of the candidate variety and 6 plants of each of the reference varieties. All plants were grown from bare-rooted plants which were transplanted into 4.4 litre containers on December 16, 2008. Observations and measurements were taken from 10 plants or parts of plants of the candidate variety and 6 plants or 10 parts of 6 plants of the reference varieties on May 11, 2009. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
