The True Virgin vigne, Virgin Virgin at five leaflets or Virginie vineyard (Parthenocissus quinquefolia) is a shrub Sarmenteux de la Family of the vitacea , originally from North America and cultivated very largely as Climbing plant Ornamental for its decorative foliage which takes A beautiful scarlet red shade in autumn.

10 seeds - stratification 2 months before sowing - sowing at 16/18 ° C

The true virgin vineyard is a shrub climbing (liana) with robust stems, very vigorous, up to 20 M high. The young shoots are reddish.

SES Leaves Caduques are composed Digitées at five (sometimes from three or seven) Leaflets Elliptics from 5 to 14 CM De Long, acuminate, with long mucroned teeth. Green-colored, they saw scarlet in autumn.

In contrast to the point of insertion of the sheet on the stem is either a Vrille or an Inflorescence. Each twist has 7 to 8 ramifications that can be used toApex to form a small hook. In contact with a surface it can then give an adhesive ball releasing adhesive substances1.

The Flowers are grouped in Rachemes of Cymes Bipares. They are made up of an entire chalice, 5 free petals, 5 stamens opposed to petals and a conical ovary. Flowering takes place in June-July.

The fruit are Bays of 6-12 MM in diameter, black in color, slightly printed. They containoxalic acid which is a toxic compound for Mammals but does not prevent birds (like starlings) from consuming them in winter.

Literature and anti -poison centers do not report serious poisoning but oral irritations and digestive disorders following the ingestion of small amounts of berries. Their consumption in large quantities (probably several dozen fruit) would cause neurological disorders and renal damage. These plants containcalcium oxalate, which seems to be the cause of their toxicity. These are therefore bays that must be considered toxic while knowing that they rarely cause serious accidents, the quantities ingested are, in fact, most often weak because of their acreté.
