Contrary to popular belief, cucumber is not a nightshade vegetable. Nightshade vegetables include a vegetable group belonging to the Solanaceae family and encompass a whole family of flowering plants.
- Cucumber belongs to the squash or gourd family called Cucurbitaceae (also called cucurbits).
- The wild variants of this family are known for their unpleasant bitter taste.
- However, domestically cultivated plants of the Cucurbitaceae family, such as cucumber, melon, squash, pumpkins, and watermelon, produce non-bitter variants.
Water and high temperature are crucial for the domestic cultivation of cucumber and melons. Vegetables produced under high stress, such as drought or low temperature, can increase the bitterness of cucumber and melons.
