In Europe, they are grown outdoors in some regions, and bees are excluded from these areas.
Most cucumber cultivars, however, are seeded and require pollination.
The vine has large leaves that form a canopy over the fruits.
Slicers in other countries are smaller and have a thinner, more delicate skin. Although any cucumber can be pickled, commercial pickles are made from cucumbers specially bred for uniformity of length-to-diameter ratio and lack of voids in the flesh.Color can vary from creamy yellow to pale or dark green.The process of pickling led to the use of paraffin wax as a seal for jars used to preserve pickled and other preserved foods, and to the Mason jar made from thick glass able to tolerate high temperatures used in processing pickles and other foods for long-term shelf-life.It is a creeping vine that bears cucumiform fruits that are used as vegetables.There are three main varieties of cucumber: slicing, pickling, and seedless.
