Which vegetable best describes the flavor of borage?

Borage, often referred to as starflower, is an herb that yields edible leaves and flowers, and its flavor profile is most closely compared to that of cucumber. The leaves have a refreshing, slightly sweet taste, which is reminiscent of the coolness of cucumbers. This makes borage a popular addition to salads and beverages, particularly in the summer.

The other vegetables listed do not share the same flavor characteristics. Carrots have a sweet and earthy flavor that's quite different from the refreshing crispness of cucumber. Kale, being a leafy green, has a robust, slightly bitter flavor that does not relate to the light and cooling essence of borage. Meanwhile, radishes have a sharp, peppery taste that contrasts sharply with the subtlety of borage's flavor. Thus, cucumber is the most suitable comparison for the flavor of borage.
