Clematis orientalis Deciduous climber (1 Page of 5) The Clematis orientalis plant species is found in W. Asia - Turkey and westwards. It is a member of the Ranunculaceae family. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Clematis orientalis Family: Ranunculaceae Author: L. Known Hazards: Although no reports of toxicity have been seen for this species, some if not all members of this genus are mildly poisonous. The toxic principle is dissipated by heat or by drying[65]. Mature Height: 4 Mature Width: Habitat: Hot dry valleys, especially on rocks by rivers, and in scrub to 3000 metres[184]. River banks, riparian forests, scrub gullies, slopes and sand depressions in semi-desert and desert zones[74].
Cultivation Notes: Prefers a deep moist soil with its roots in the shade[11, 200]. Dislikes poorly-drained heavy clay soils, but grows well in clay if grit is added for drainage[11, 200]. Dislikes light sandy soils[11]. Does well on chalk[1]. Succeeds in acid as well as alkaline soils[200].
Plants are hardy to about -15°c[184].
A twining plant[182]. The leafstalks wrap themselves around twigs and branches for support. When a side of the stalk touches an object, the growth on that side slows down whilst the other side grows at its normal rate - this causes the leaf stalk to entwine the object it is touching[212].
When planting out, in order to avoid the disease 'clematis wilt', it is best to plant the rootball about 8cm deeper in the soil. This will also serve to build up a good root crown of growth buds[200].
Flowers are produced on the current season's growth, any pruning is best carried out in spring[219].
Plants in this genus are notably resistant to honey fungus[200].
Plants seem to be immune to the predations of rabbits[233].
A greedy plant, inhibiting the growth of nearby plants, especially legumes[54].
The flowers have a delicate perfume similar to cowslips[245].
