The Canadian vine (Parthenocissus Tricuspidata) is a plant belonging to the Vitaceae family, like the most common American vine (Parthenocissus Quinquefolia L.) and European vine (Vitis Vinifera); while the first two are ornamental vines, only the European vine is cultivated for the production of wine. Ornamental vines are considered "sterile", that is, not suitable for winemaking: in fact, the name parthenocissus itself derives from the Greek and means "virgin ivy". The name "tricuspidata" refers to the characteristic shape of the leaf which, as for other vine species, has three ends also known as "cusps".
Its origins are recognized in areas of North America, although some varieties would appear to originate in Asia. The term Canadian vine, therefore, means a family that includes about fifty different varieties, all characterized by the climbing habit of the shrub, which can reach up to 15 meters in height and by the typical deciduous leaves. The fruits are berries that reach full maturity in late autumn, assuming an intense blue-violet color. As an ornamental vine it is widely used to cover pergolas, walls and natural or artificial structures, thanks to its dense foliage which assumes a characteristic and intense reddish color just before autumn. The growth is luxuriant and fast although it does not require, as we will see, particular care or attention; all these characteristics make it a plant of choice as regards the choice of ornamental creepers both for outdoor and, in some cases, for indoor.
Exposure and characteristics of the soil
There Canadian lives it is well suited to sunny exposures, although it can very well find its habitat in less sunny situations, up to full shade, conditions which however make the production of flowers and fruits unfavorable, even if, given the ornamental function characteristic of the leaves , does not appear to be significant damage.
It adapts well to any type of soil, as long as it is rich in organic substances, of which it is particularly greedy; good drainage then helps the plant to grow more luxuriantly.
