[edit] Naming
Clematis viticella was described in 1753 by Carl Linnaeus. The name is considered as validly published.
[edit] Taxonomy
Clematis viticella is a species in the genus Clematis (virgin's bower) which contains 295 species and belongs to the family of the Ranunculaceae (Buttercup Family).
[edit] Characteristics
[edit] Growth
The climbers usually grow to a height of two to four, sometimes also to five metres. They have delicate shoots and grow at a moderate rate.
[edit] Leaves
Clematis viticella is a decidious plant with imparipinnate leaves. These are arranged alternately along the stems. The proximal leaves sometimes are tri-foliate. The fresh green, somewhat leathery leaflets are broadly ovate to lanceolate or elliptic. The are entire to one- to three-lobed and have entire margins.
[edit] Flowers and Fruit
The bell-shaped flowers consist of four sepals and numerous stamens. They are blue to purplue or rose-purple. The sepals are silky-pilose on der outside wich makes the velvety to the touch. The flowers are arranged solitary and appear from June to September. They are rather small compared to other Clematis but appear abundantly.
The fruits are nutlets.
[edit] Distribution
Clematis viticella is native to Italy, the Balkan Peninsula, Turkey, Cyprus, the Caucasus and Iran, and is naturalized in France, Germany and the Czech Republic.
[edit] Cultivation
Clematis viticella prefers a sunny to half shady site and can withstand temperatures down to -23,3º C. It is important that the "foot" of the plants is in the shade. This can be achieved for example by planting low shrubs or bushy perennials. It grows best in sandy or gritty, loamy soil and sandy clay that is moderately moist. They do not tolerate stagnant moisture.
[edit] Uses
The Italian clematis needs a climbing aid. This can either be built structures such as pergolas, trellises and rose arches but also trees, shrubs or hedges. Roses generally are good companions for Clematis.
[edit] Maintenance
Cutting the plants back to within 50 centimetres of base in early spring promotes healthy growth.
[edit] Cultivars
Selection of Clematis viticella cultivars focuses mainly on flower colour, filling and form of the sepals.
[edit] Poisonousness
Clematis viticella is poisonous.
