Cucumber

Cucumis sativus

Cucumbers are a refreshing and versatile vegetable, enjoyed fresh in salads, sandwiches, and pickles. They are typically categorized into outdoor (ridge) varieties, ideal for cooler climates, and greenhouse varieties, which prefer warmer conditions. Modern varieties often thrive in both environments. Gherkins are small, immature cucumbers, perfect for pickling.
