10 Graines Vigne vierge japonaise, Parthenocissus tricuspidata
Japanese vineyard, Parthenocissus tricuspidata |
Parthenocissus tricuspidata is a flower plant of the family of grapes ( vitaceae ) from Asia Orientale in Korea , In Japan and in the North and East of China . Although it is not related to the true ivy , it is commonly called the ivy of Boston , Grape ivy and Japanese ivy , as well as Japanese Liane , and under the name of Woodbine (although the latter can refer to a certain number of different vine species).
It is a vine Local with deciduous leaves reaching 30 m high or more with an appropriate support, fixing by means of many small ramified tendrils ended by sticky discs. The Leaves are simple, palmate lobes with three lobes, sometimes not lobed or five lobes, or sufficiently deep lobed to be webbed to (generally) three leaflets; The leaves are 5 to 22 cm in diameter. The Flowers are discreet, greenish, in clusters; The Fruit is a small Raisin Dark blue of 5–10 mm in diameter.
The specific epithet Tricuspidata means three points, referring to the shape of the sheet. 
Like the virgin vine related, this plant is largely cultivated as ornamental plant climbing to cover the facades of masonry buildings. This use is in fact economically important because, in shading walls during the summer, it can considerably reduce cooling costs.
Boston's ivy is easily distinguished from virgin vine by its simple leaves with pointed lobes (the leaves of the virgin vine are divided into five leaflets distinct).
The plant secretes calcium carbonate,  which serves as an adhesive buffer and gives it the ability to fix a wall without requiring additional support. Although it does not enter the surface of the building but simply get attached to it, damage can nevertheless occur by trying to tear the plant from the wall. However, if the plant is killed first, for example by separating the vine from the root, the adhesive pads will eventually deteriorate to the point that the plant can be easily removed without damaging the wall.
It is used on external brick walls of Wrigley Field of Cubs de Chicago with Japanese Sweet Brewers.
