It is primarily known for good tolerance against soils with a high content of lime, which can cause chlorosis in many vines of American origin. Lime is a characteristic of the soils of many classical French wine regions and highly regarded vineyard sites, and many Vitis vinifera cultivars were well suited to these growing conditions. When American vines were imported to Europe as rootstocks for grafting V. vinifera on, in the wake of the Great French wine blight, it initially proved difficult to find vine species that would grow well in lime-rich soil. V. berlandieri, which had adapted to limestone hills in central Texas, provided the lime tolerance needed to solve this problem. However, V. berlandieri itself is poorly adapted to grafting. Therefore, various rootstocks resistant against both phylloxera and lime, and suitable for viticulture, were produced by crossing V. berlandieri and Vitis riparia, Vitis rupestris or V. vinifera.
Vitis berlandieri is also known as Fall Grape.
In some classifications it is considered to be a subspecies of Vitis cinerea.
The flowers are lavender-blue or pinkish-lilac, with five to ten petals and a quite protruding yellow centre. Leaves are small, elongated and untoothed. This plant grows to a height of about 6090 cm (23 ft) at an altitude of 01,200 m (03,900 ft) above sea level. The period of flowering is from July until late autumn.
It is a perennial growing up to 50 cm tall with fleshy lanceolate leaves and purple ray florets flowering from July to September. The plants tend to be short-lived and populations need significant new recruitment each year from new seedlings. There are rayed as well as rayless varieties and only the former have long blue or white florets. The rayless form is yellow. The plant flowers well into autumn and hence provides a valuable source of nectar for late-flying butterflies such as painted lady and red admiral.
Petroselinum crispum (garden parsley) from southern Europe and northern Africa (southern Italy, Greece, Algeria, Tunisia) is an important culinary herb, widely used for flavouring and as a vegetable.
Petroselinum segetum (corn parsley) from western Europe (Great Britain and the Netherlands south through France to Italy, Spain and Portugal) is also edible with a similar flavour, but is not widely cultivated. It occurs in grassland, hedgerows, and river banks. In Great Britain it is confined to lowland regions in southern and central England and southern Wales, and is scarce and declining due to agricultural intensification. It has narrower, more lanceolate leaves than garden parsley, only single pinnate, not tripinnate.
