Pistil: style white plumose, stigma short hairy, white.

General description:A hardy perennial-like plant with stems up to 1.5 m long but much shorter when pot grown. Leaves compound, ternate or pinnate, normal green coloured with purple margin. Flower 3.5 cm across, very nicely shaped campanulate, dark glossy violet including the flower buds. The flowers attract a lot of bees and are slightly fragrant.
Flowers from June into August in the Northern hemisphere when pruned in winter at 10 cm above soil level, followed by nice silvery seed heads. Zone 5.
Origin:Raised by Wim Snoeijer from deliberate crossbreeding in 1992. The seedplant used was Clematis 'Olgae' (Integrifolia Group) pollinated with Clematis fusca. These plants grew in the clematis collection of Jan Fopma, Boskoop, The Netherlands. Several plants could be raised as the seeds germinated in spring 1993 but only one plant was selected in 1996. In that same year Jan Fopma retired and Jan van Zoest, already clematis grower in Boskoop, took over the collection and trade from Jan Fopma. He propagated the plant and was named in 1998 and introduced by J. van Zoest B.V., Boskoop, The Netherlands, in 2002.
Clematis 'Fascination' was recognised by the Royal Boskoop Horticultural Society with an Award of Merit in 2002 and received a Silver Medal at Plantarium in that same year.
The cultivar has been granted European Plant Breeders Right no 11471, Japanese Plant Breeders Right no 15968 and US Plant Patent no 14,770.
Growing, trading and sale as a pot plant and/or as a cut flower is only permitted under a contract.

Seed plant:Clematis 'Olgae' (Integrifolia Group) used for this crossbreeding was grown in the clematis collection of Jan Fopma, Boskoop, The Netherlands. Jan Fopma obtained his plant from Carol & Keith Fair of Valley Clematis Nursery, United Kingdom. The origin of the cultivar is a bit uncertain but it is known that Treasures of Tenbury, Burford House, United Kingdom, offered the plant at least in 1963. This cultivar is a true Integrifolia Group cultivar (see reference Wim Snoeijer (2008) Clematis Cultivar Group Classification. Private publication.) and has nothing to do with plants or names classified under Clematis × diversifolia or with plants or names classified in the Diversifolia Group.
Pollen plant:The form used of Clematis fusca had glossy violet flowers, sometimes referred to as Clematis fusca subsp. violacea, Clematis fusca var. violacea or as Clematis ianthina. At botanical level, meaning for wild species, these latter names are not accepted (anymore) and are a synonym of Clematis fusca.
In the garden, however, these plants can be readily recognised from each other but they have, of course, nothing to do with species growing in the wild.
