- Zucchini: A green-skinned, summer squash, typically elongated and mild in flavor .

| Color | Yellow, white, green (depending on type) | Dark green, sometimes yellow or striped |

Types of Squash: Beyond Zucchini
Squash comes in two broad categories: summer squash and winter squash. Zucchini and yellow squash are the stars of summer, harvested when still tender and eaten with the skin on.
