From the pattern:
What an adorable bunch of little fruit-and-vegetable hats viewer Julie Watson knitted and sent to us to share with you. Inspired by a single photo of a strawberry hat that she saw in a magazine, Julie knitted and could have filled an entire produce department with lemon, peach, eggplant, strawberry and pumpkin hats. All were identical except for the pumpkin, which had ridges.

You could use this pattern in a variety of color combinations for the different fruits or veggies, such as a red hat with green stem/leaf for strawberry, as is shown on the pattern.
