Then, there are eggplant blossoms, which are so much more complex than the one-color tomato or squash flower. (Not that I don't love bright yellow blossoms; they're pretty in their own way.) An eggplant bloom is as attractive as any border flower, with its light-purple petals and deep yellow center. Visually, I think it's my favorite vegetable garden flower.
And, of course, eggplant fruit is gorgeous--so glossy and deep purple. When I see them on the table at the farmers' market, I always have to buy some, especially the striped Listada de Gandia variety, which I am currently growing. Sadly, I don't have any photos of eggplant growing in my garden yet. They are taking their time. But I should have some nice ones in a couple of weeks.
So, that's my little ramble about the beauty of the eggplant. Perhaps you may disagree, but eggplant is my pick for prettiest summer vegetable.
