Cucumber is easy to grow. Varieties, varying in size, shape, and color, are cultivated all around the world under different climatic zones. In general, the fruit features dark-green skin, crispy, moisture rich flesh, and small edible seeds concentrated near its core.

As in other squash members, cucumbers too are best harvested young, tender and just short of reaching maturity; at the stage when they taste sweet, have a crunchy texture, and almost neutral flavor. If left uninterrupted, the fruit continues to grow, its skin becomes tougher and turns yellow, and seeds become hard and inedible. Fresh cucumbers are available throughout the season and can be eaten raw, in vegetable salads or juicing.

Armenian cucumbers (Cucumis melo var. flexuosus) are long, crispy, thin-ribbed, curvy, and possess light green color. Although grouped botanically in the melon family, they appear and taste just like cucumbers.

Miniature varieties such as gherkins, American-dills, and French cornichons are tiny in size and usually preferred in pickling.

Dosakayi is a yellow Indian curry cucumber. It has mild sweet taste and neutral flavor. It is used extensively in the preparation of stews and curries, particularly during the summer season in southern parts of India and Sri Lanka.

These compounds help act as protective scavengers against oxygen-derived free radicals and reactive oxygen species (ROS) that play a role in aging and various disease processes. Their total antioxidant strength, measured in terms of oxygen radical absorbance capacity (ORAC value), is 214 µmol TE/100 g.
