Variety Description

Variety used for comparison: 'Niobe'

Summary: 'Evifive' is a climbing Clematis variety which has longer leaves and larger flowers than the reference variety 'Niobe'. The sepals of 'Evifive' are very long, whereas the sepals of 'Niobe' are medium in length. The sepals of 'Evifive' have 2 colours while the sepals of 'Niobe' have only 1 colour on the upper side. The margins of the sepals of 'Niobe' are strongly undulating giving them a ruffled appearance, compared with the candidate variety which has moderately weak undulation of the sepal margins.


'Evifive' is a climbing type Clematis variety which has sparse to medium pubescence on the young shoots, consisting of medium length hairs. There are both simple and ternate leaves. The blade of the leaflet is long and medium in width. The leaflets are lanceolate, with a narrowly acute apex and an acute base. The leaflet blade margins are entire. The leaflets of 'Evifive' may have lobing with two to four lobes. The leaves are medium green in colour with moderate rugosity. The lower side of the leaflets is very sparsely pubescent.

'Evifive' bears solitary, single flowers, which are large in diameter and rotate in shape. The flowers face upwards and outwards. In lateral view they are flat to convex. There are 6 to 8 sepals, which are free and not touching each other. The flowers of 'Evifive' have a weak fragrance.

'Evifive' has sepals which are very long and very broad. They are elliptic in shape. In cross-section the sepals are flat to convex. In longitudinal section they are moderately reflexed. The apex is acute with an acuminate tip and the base is type 3. Sepals of 'Evifive' have two colours on the upper side. The main colour is light purple, and the central bar is dark red-purple. The lower side of the sepal is light purple with a dark reddish purple central bar. The margin of the sepals is weakly undulating, and there is no twisting along the longitudinal axis. Flowers of 'Evifive' have no petaloid stamens. 'Evifive' has light violet filaments with yellow coloured anthers and a creamy white stigma.

'Evifive' flowers on both the previous year's and current year's growth. It begins flowering early to mid-season (about week 24 in St. Thomas, Ontario).

Origin & Breeding History: 'Evifive' originated from a cross in 1988 between two unnamed seedlings at the Guernsey Clematis Nursery in Guernsey, Channel Islands, United Kingdom. The resulting seeds were planted in a controlled environment. Selection of the seedling known as 'Evifive' occurred in 1989/90.

Tests & Trials: Tests and trials for 'Evifive' were established in the field during the spring of 2002, and observations and measurements were taken during the spring of 2003 at BioFlora, Inc., St. Thomas, Ontario. Eight rooted plants of the candidate and reference varieties were received April 20, 2002 and planted into 11.5 cm pots and grown in a polyhouse. Young plants were transplanted to the field on June 3, 2002. Plants were spaced 60cm apart and trained to grow along a trellis. Observations and measurements were taken from 10 plant parts of each variety during June 2003. All colour measurements were made using the 2001 RHS Colour Chart.
